Dates For The Diary

2015 has been the almost eventful twelvemonth of my teaching career to date. I returned to piece of job from motherhood exit inwards Jan as well as took on a Lead Practitioner move at a novel schoolhouse vi months later. I continued to last a busy blogger as well as tweeter throughout the twelvemonth as well as was chuffed that my efforts were recognised at the United Kingdom of Great Britain as well as Northern Ireland Blog Awards inwards April. During 2015 I attended numerous teaching events including maths conferences, TeachMeets, debates as well as my real ain Christmaths party. Although it's tempting to write a long as well as rambling reflection of all the events of the year, instead I've decided to await at what 2016 has to offer. There's loads going on inwards the twelvemonth ahead as well as this post lists a few highlights. Full listings tin laissez passer the sack last constitute here.

January
Back to schoolhouse as well as the chaos starts all over again. If your schoolhouse is form plenty to allow you lot out for a day, I reckon La Salle's National Maths Education Symposium on Th 21st Jan is worth a look. The programme is excellent.

I'm incredibly jealous of anyone who is able to attend the adjacent Peterborough Maths Network event. They've solely managed to describe of piece of job upwards the almost awesome mortal inwards the maths teaching - Don Steward! This lawsuit takes house after schoolhouse on 19th Jan as well as you'd last foolish to fille it.

It's also my birthday on sixth January... simply saying.

February

It's a outflow year! Did you lot run into this tweet from Matt Parker? I ♥ numbers.

Sure, 2016 is non divisible yesteryear five similar 2015, but it is divisible yesteryear EVERY OTHER SINGLE-DIGIT NUMBER. quaternary fourth dimension ever. Max possible until 2520.

March as well as April
Have you lot noticed how curt the Spring Term is? Easter falls early on inwards 2016. As a upshot there's an awful lot going on during March.

The write-up of the final conference to larn an persuasion of what goes on.

I'm also actually looking forwards to Julia Smith's (@tessmaths) Easter Maths Camp which is on 28th as well as 29th March in sunny St Osyth, Essex. There's all sorts of lovely activities lined upwards - contact Julia if you lot desire to larn involved.

As always, the ATM as well as MA are belongings their conferences over the Easter holidays. The ATM's Easter Conference 2016 is inwards Warwick from Tuesday 29th March to Fri 1st Apr as well as the MA Annual Conference 2016 takes house inwards Oxford from Fri 1st Apr to Lord's Day tertiary April. Both get got fantabulous programmes. Hopefully when my children are older I'll last able to attend i of these residential conferences.

Influenza A virus subtype H5N1 distich of weeks into the Summer Term is my write-up here) as well as therefore if you lot larn the adventure to go, I actually recommend it.

July as well as August
I'll last presenting on Influenza A virus subtype H5N1 degree resources at the annual FMSP Key Stage five Teachers Conference inwards London on eighth July - details to follow.

Tom Bennison (@DrBennison) is organising an East Midlands KS5 Mathematics Conference on ninth August at the University of Nottingham. With the upcoming implementation of new Key Stage five specifications, Influenza A virus subtype H5N1 degree CPD is going to accept centre phase over the adjacent 2 years. Tom is planning what sounds similar an fantabulous lawsuit - I volition part details when they are announced.

September to December
#mathsconf8 takes house inwards Manchester on 1st Oct - it's a fleck of a trek for me but I wouldn't fille it!

I'm certain there'll last lots to a greater extent than Autumn Term events announced closer to the time. Maybe fifty-fifty a #christmaths16... And (fingers crossed) I actually promise to organise something when the novel maths gallery opens at the Science Museum. Watch this space.

Quick - larn these dates inwards your diary now!

Throughout the twelvemonth there's loads of fantastic local events organised yesteryear bodies such equally the Further Maths Support Programme as well as the Maths Hubs. I haven't listed everything here, but there's ever plenty going on for maths teachers as well as therefore create honor out what's happening inwards your area.

I await forwards to seeing you lot at an lawsuit inwards 2016.

Happy New Year!

5 Maths Gems #112

Welcome to my 112^th gems post. This is where I portion some of the latest news, ideas as well as resources for maths teachers.

1. Classic Errors
I similar this activity suggested past times James Tanton (@jamestanton). James asks 'Would taking classic as well as tempting errors "head-on" endure a worthwhile classroom activity as well as discussion?'.  It's worth reading the responses inwards the thread. In it Cathy Yenca‏ (@mathycathy) recommends the classic resources 'Algebra Atrocities' which is worth a look.
2. Geogebra Percentages
Thanks to Mark Horley (@mhorley) for sharing some helpful Geogebra applets created by ⁦‪@orchiming‬⁩ .

These interactive tools assist amongst explanations of percentages. For instance the turn a profit as well as loss applet shows actually clearly how the calculation works.

3. Area Mazes
I know I've featured Area Mazes inwards my gems posts an set out of times before, only I mean value they're actually fun thus there's no impairment inwards mentioning them again. Have a learn at this ane -  it was tweeted past times @Errs5 and is taken from the Area Quiz app which looks excellent.

4. Calculator Crunch
In my post almost Year 11s lacking basic estimator skills I mentioned that MEI are running Calculator Crunch to encourage schools to learn younger pupils using calculators. Aimed at Year vi as well as 7, they are sharing a daily estimator challenge betwixt tenth as well as 20th June. You tin download all the daily challenges from the MEI website and purpose them at whatsoever time. They get got also provided a Year vi lesson excogitation as well as a Year 7 lesson excogitation that you lot tin download here.

Check out the hashtag #CalculatorCrunch to run into examples of pupils' work.

5. Place Value
Another neat thought for using calculators is inwards a lesson on house value. Tom Francome shared this 'Place Invaders' task in a conference workshop - it's taken from the ATM mass Practising Mathematics which he wrote amongst Dave Hewitt.

Grab a estimator as well as get got a learn as well as you'll run into why this is a neat chore to purpose when teaching house value. I mean value that house value is ane of the hardest things to instruct inwards Year 7 thus it's helpful to run into a expert character activity for this. Tom suggested it would also function good amongst criterion form.

Update
Exam flavor is nearly over, as well as it's been an unusually turbulent ane this year. We've had questions that appeared to endure copied from textbooks, a error inwards an Influenza A virus subtype H5N1 level, controversial contexts, a leaked bear witness as well as some surprisingly challenging Influenza A virus subtype H5N1 score papers. Never a placidity twenty-four hours inwards maths education!

I late made a GCSE revision resources page. You mightiness discovery these resources helpful if you lot get got Year 10s preparing for halt of yr exams.

I presented at ResearchED Rugby yesterday. My session focused on multiplication - kickoff nosotros looked at a hit of multiplication methods as well as and thus I presented a critique of each of the reasons the Government gave for prescribing 'formal' methods at Key Stage 2. For the residue of the twenty-four hours I attended fantabulous sessions inwards the maths strand. Rugby School has an incredible history thus was a cool venue for a conference.

Next weekend I'll endure presenting on the Evolution of Maths Vocabulary at La Salle's conference inwards Yorkshire. Read my weblog post "Whatever happened to vulgar fractions?" to learn an thought of the sort of affair I'll endure talking about, as well as if you lot discovery it interesting as well as thus produce come upwards along to my workshop. I'll also endure manning the MA bookstand for most of the twenty-four hours thus produce come upwards as well as tell howdy if you lot learn the chance.

Bookings are going good for the training course I'm running amongst Craig Barton inwards October. This course of written report is opened upwards to all maths teachers as well as nosotros get got 2 dates available - a northern leg as well as a southern leg. Ask your schoolhouse or college to book your house now if you lot desire to come upwards along.

At the halt of May Ed Southall as well as I relaunched The Mathematical Association's eNews. This monthly newsletter provides an update of what's going on amongst the MA as well as also inwards the wider footing of maths education. We similar a shot characteristic exclusive monthly puzzles for your students (written past times Ed), as well as in that place are to a greater extent than novel features coming soon. You tin subscribe here to have eNews from the halt of June.

I've been kindly sent a twosome of books past times their authors recently. Kyle D Evans sent me a re-create of 'Here Come the Numbers' which my daughters (aged 5 as well as seven) beloved every bit a bedtime story. It's both mathematical as well as lovely.

Mark Ritchings sent me a re-create of 'GCSE Maths Challenge' which contains twoscore GCSE manner questions that are aimed at pupils who are working at a Grade 8 or 9. This curt mass mightiness endure helpful for a GCSE tutor, or maybe a exceed laid instructor who needs a few extra ideas for extension questions to write on the board.

Maths instructor Richard Atkin (@RichardAtkin1) - whose uncle was a Trustee of the MA - really kindly delivered an enormous set out of former maths books to my house. This volition popular off along me busy for a while! I've already constitute lots of treasures that get got taught me novel things. I gauge that I similar a shot ain at to the lowest degree 300 unlike maths textbooks dating from 1800 to 2000. I beloved this!

Influenza A virus subtype H5N1 grouping of us are going to Matt Parker's Humble Pi comedy exhibit on 16th July inwards London (it's a preview of his Edinburgh Fringe show). If you lot desire to bring together us, mass a ticket here as well as allow me know you're coming. There are similar comedy nights inwards London listed here, including ane that features the amazing FoxDog Studios. FoxDog Studios volition also endure at Edinburgh Fringe as well as are doing gigs inwards diverse locations earlier as well as thus - dates are listed here. They are amazing.

I'll exit you lot amongst this neat activity shared past times Sarah Carter (her blog. This puzzle mightiness function good inwards a kickoff Year 7 lesson inwards September, along amongst the other tasks I listed inwards my post Year 7 Maths Activities.

I'll exit you lot amongst this neat activity shared past times Sarah Carter (her blog. This puzzle mightiness function good inwards a kickoff Year 7 lesson inwards September, along amongst the other tasks I listed inwards my post Year 7 Maths Activities.

Pythagoras' Theorem

Pythagoras' Theorem is ane of my favourite topics to teach. In my experience, students quite similar it too. At outset they may hold out intimidated past times the novel as well as seemingly complex mathematics. It's in all probability the outset fourth dimension they've seen words such equally theorem, proof as well as hypotenuse thus no wonder they're apprehensive. But they'll rapidly larn the hang of it.

When H5N1 score students receive got to discovery the distance betwixt 2 points or verify that a triangle is right-angled, their outset thought should hold out Pythagoras. By Year 12, Pythagoras' Theorem should hold out a staple inwards their mathematical toolkit, along alongside other skills such equally arithmetic, fractions, simplifying algebra, using index laws as well as factorising quadratics. In my sentiment these things are the breadstuff as well as butter of secondary schoolhouse higher mathematics.

I'm going to affect briefly on proofs at the terminate of this postal service but my master copy focus is on interesting Pythagoras questions as well as resources for Key Stage 3 as well as 4. Before nosotros start, I should number my commons caveat - there's absolutely loads of fantabulous Pythagoras resources online as well as hither I'm exactly showcasing a small-scale selection.

Interesting Questions
It's non ever necessary to strength a inquiry into a 'real world' context to larn inwards engaging. Problems don't receive got to hold out contextual to hold out interesting - sometimes the real best questions are abstract but accessible.

In this example from illustrativemathematics.org, students receive got to operate out whether the shaded triangle is right-angled.

This Spiderbox question, also from Illustrative Mathematics, appears at outset glance to hold out a 3D Pythagoras inquiry but truly the spider is walking on the exterior of the box. Students brand a net, depict the spider's path as well as operate out its length.

amusing post from Math Jokes four Mathy Folks.

I also recollect it's worthwhile spending a few minutes discussing the pregnant of the give-and-take theorem as well as how it differs from a theory. H5N1 theorem is a consequence that has been proven to hold out true, for instance using logical arguments as well as previously established mathematical statements. Theory is a give-and-take used both inwards everyday life (eg 'the detective had a theory most who committed the murder') as well as inwards scientific discipline (such equally Einstein's theory of relativity). In everyday linguistic communication it has a pregnant similar to hypothesis. In science, a theory is a contemplative as well as rational type of abstract thinking. H5N1 theory exactly attempts to explicate something whereas a theorem is established mathematical fact. There's to a greater extent than on this two diagonals' as well as exactly about other called 'amusing post from Math Jokes four Mathy Folks.

Helpful Worksheets

horacek.com.au

This 'Investigating the sides of right-angled triangles' worksheet from Teachit Maths is a straightforward activity inwards which students travail to 'discover' Pythagoras' Theorem past times drawing right-angled triangles as well as investigating the human relationship betwixt the lengths of their sides. Teachit Maths also provides a 'Pythagoras' Theorem - consummate theme booklet' which covers the total theme from elementary exercise questions to work solving, using surds as well as 3D Pythagoras.

These Pythagoras' Theorem Student Sheets (& notes) from Nuffield Foundation comprise adept work solving questions, equally does Pythagoras Problems from The Chalk Face.

I've written a Pythagoras Pret homework - run across this page for to a greater extent than data most Pret homeworks.

Adding a Third Dimension
During my PGCE I had my students laid cuboids out of piping cleaners as well as operate out how to discovery the length of the infinite diagonal past times themselves. The piping cleaners were a faff that I won't hold out repeating but figuring out how to discovery the length of a infinite diagonal is definitely something students tin produce themselves. Perhaps the easiest prop to role is your classroom. When I learn 3D Pythagoras I ordinarily gesture at an imaginary infinite diagonal beingness drawn from the lower left corner to upper correct corner of the room. In fact it would hold out amend to attach exactly about string or wool to the walls thus you lot receive got an actual infinite diagonal going across the room, to assist students visualise the correct angled triangles.

There's 2 approaches to pedagogy 3D Pythagoras. One is to receive got the pupils derive the formula for the infinite diagonal (eg d² =  x² + y² + z²) as well as and thus memorise it. This may hold out useful afterwards on, for instance when they report vectors inwards C4, but it's non helpful when they come upwards to 3D trigonometry. My preferred approach for 3D problems is that they position as well as separately depict the 2 correct angled triangles inwards question. I encourage them to overstep on their workings inwards surd cast for accuracy.

Good 3D questions are available inwards these Trigonometry Worksheets (see exercise T7) past times Frank Tapson (from the Cleave Books website).

Also, here's a prissy 3D Pythagoras activity 'amusing post from Math Jokes four Mathy Folks.

I also recollect it's worthwhile spending a few minutes discussing the pregnant of the give-and-take theorem as well as how it differs from a theory.

H5N1 theory exactly attempts to explicate something whereas a theorem is established mathematical fact. There's to a greater extent than on this Cuboid Diagonal' from Don Steward.

Triples
Pythagorean Triples are fun to explore alongside your students. Before you lot do, receive got the chance to print them alongside your apparent super-quick mental arithmetics ("the 2 sides are five as well as 12 you lot say? Well the hypotenuse must hold out 13").

Activity 3.4 inwards this set of activities from the Mathematics Enhancement Programme is a brusque as well as accessible investigation into Pythagorean Triples. The Mathematics Assessment Programme also has a Pythagorean Triples activity and Don Steward has students looking for patterns. There are many to a greater extent than substantial investigations available online.

Pythagoras of Samos
Apparently Pythagoras was the outset individual to telephone phone the heavens a universe as well as the Blue Planet round. He also (allegedly) headed upwards a surreptitious cult of Pythagoreans who weren't allowed to consume beans. Pythagoras said that "each number has its ain personality - masculine or feminine, perfect or incomplete, beautiful or ugly". The mysterious story of Pythagoras of Samos is truly interesting as well as would brand a adept theme for inquiry or display work.

Pythagorean Proofs
I won't verbalise likewise much most proofs because I'll hold out hither all day. I must advert this vivid H2O demonstration video though.



If you lot desire your students to attempt exactly about proof activities, this line 'Proofs of the Pythagorean Theorem' from Mathematics Assessment Project is most comparison 3 unlike proofs.

Finally, Don Steward's spider web log features amusing post from Math Jokes four Mathy Folks.

There's to a greater extent than on this Herve Lehning's posters of Pythagoras past times agency of dissections which are real pleasing to the eye.

I promise this has been helpful if you're planning Pythagoras lessons. Please comment if you lot receive got whatever ideas to add.

This 'Investigating the sides of right-angled triangles' worksheet from Teachit Maths is a straightforward activity inwards which students travail to 'discover' Pythagoras' Theorem past times drawing right-angled triangles as well as investigating the human relationship betwixt the lengths of their sides. Teachit Maths also provides a 'Pythagoras' Theorem - consummate theme booklet' which covers the total theme from elementary exercise questions to work solving, using surds as well as 3D Pythagoras.

These Pythagoras' Theorem Student Sheets (& notes) from Nuffield Foundation comprise adept work solving questions, equally does Pythagoras Problems from The Chalk Face.

I've written a Pythagoras Pret homework - run across this page for to a greater extent than data most Pret homeworks.

Adding a Third Dimension
During my PGCE I had my students laid cuboids out of piping cleaners as well as operate out how to discovery the length of the infinite diagonal past times themselves. The piping cleaners were a faff that I won't hold out repeating but figuring out how to discovery the length of a infinite diagonal is definitely something students tin produce themselves. Perhaps the easiest prop to role is your classroom. When I learn 3D Pythagoras I ordinarily gesture at an imaginary infinite diagonal beingness drawn from the lower left corner to upper correct corner of the room. In fact it would hold out amend to attach exactly about string or wool to the walls thus you lot receive got an actual infinite diagonal going across the room, to assist students visualise the correct angled triangles.

There's 2 approaches to pedagogy 3D Pythagoras. One is to receive got the pupils derive the formula for the infinite diagonal (eg d² =  x² + y² + z²) as well as and thus memorise it. This may hold out useful afterwards on, for instance when they report vectors inwards C4, but it's non helpful when they come upwards to 3D trigonometry. My preferred approach for 3D problems is that they position as well as separately depict the 2 correct angled triangles inwards question. I encourage them to overstep on their workings inwards surd cast for accuracy.

Good 3D questions are available inwards these Trigonometry Worksheets (see exercise T7) past times Frank Tapson (from the Cleave Books website).

Also, here's a prissy 3D Pythagoras activity 'amusing post from Math Jokes four Mathy Folks.

I also recollect it's worthwhile spending a few minutes discussing the pregnant of the give-and-take theorem as well as how it differs from a theory.

H5N1 theory exactly attempts to explicate something whereas a theorem is established mathematical fact. There's to a greater extent than on this Cuboid Diagonal' from Don Steward.

Triples
Pythagorean Triples are fun to explore alongside your students. Before you lot do, receive got the chance to print them alongside your apparent super-quick mental arithmetics ("the 2 sides are five as well as 12 you lot say? Well the hypotenuse must hold out 13").

Activity 3.4 inwards this set of activities from the Mathematics Enhancement Programme is a brusque as well as accessible investigation into Pythagorean Triples. The Mathematics Assessment Programme also has a Pythagorean Triples activity and Don Steward has students looking for patterns. There are many to a greater extent than substantial investigations available online.

Pythagoras of Samos
Apparently Pythagoras was the outset individual to telephone phone the heavens a universe as well as the Blue Planet round. He also (allegedly) headed upwards a surreptitious cult of Pythagoreans who weren't allowed to consume beans. Pythagoras said that "each number has its ain personality - masculine or feminine, perfect or incomplete, beautiful or ugly". The mysterious story of Pythagoras of Samos is truly interesting as well as would brand a adept theme for inquiry or display work.

Pythagorean Proofs
I won't verbalise likewise much most proofs because I'll hold out hither all day. I must advert this vivid H2O demonstration video though.



If you lot desire your students to attempt exactly about proof activities, this line 'Proofs of the Pythagorean Theorem' from Mathematics Assessment Project is most comparison 3 unlike proofs.
