5 Maths Gems #49

Hello as well as welcome to my 49^th gems post. This is where I portion 5 maths teaching ideas as well as render an update on some of the things that bring been happening inwards U.K. maths education.

1. Revision Mats
Grant Barker (@AccessMaths) has created some fantabulous revision mats. Like all of Grant's resources, these are really good designed.

For to a greater extent than GCSE revision resources, run across my postal service Higher GCSE Revision.

2. MathsBot

I've sung the praises of Jonathan Hall's (@StudyMaths) website formtimeideas.com many times before. If you're a shape tutor as well as yous don't know nearly this website as well as thence you're missing out! I've used it for tutor groups from Year seven through to Year 12. In add-on to formtimeideas.com, Jonathan runs some fantabulous maths websites - my favourite is Flash Maths.

It's worth checking out Jonathan's recent updates to MathsBot.com. This includes numerous helpful tools including a Starter Generator which allows yous to pick out topics as well as difficulty level:

3. Key Marks

Thanks to Billy Adamson (@Billyads_47) for creating a 'Key marks earned inwards GCSEs' resource. These slides characteristic elementary strategies as well as facts that Billy's students remove to larn for their GCSE exams. Weekly testing over the adjacent few months (for illustration amongst mini-whiteboards) volition survive a proficient agency to tending students memorise these fundamental points.

4. Truncation

Truncation is a novel GCSE topic. My colleague Rachel (@miss_middletonr) has a actually squeamish agency of helping students recollect how to truncate numbers.

When I tell I'm 35 years old, I haven't rounded my historic menses to the nearest integer. I've truncated my age. So when I tell I'm 35, yous know my historic menses is betwixt 35 as well as 36:

35 ≤ age < 36

This is an incredibly straightforward as well as accessible agency to instruct mistake intervals. Thank yous for the consider Rachel!

5. Launch - Underground Maths
If you've been next the progress of CMEP then yous likely already know that their fantastic Influenza A virus subtype H5N1 bird resources are going to survive hosted on the novel website undergroundmathematics.org which launches on Monday. Follow @UndergroundMath for updates. I dear their 'teddy bear' activeness for the equation of a circle.

Recommended Reading
I recommend that yous read these recent articles as well as publications if yous haven't already:

Edexcel's novel Maths GCSE Assessment Guide. I flora it interesting to read that formulae volition survive given inwards the interrogation rather than on a formula sheet. Also, although it's non novel information, the judgement "Previously, 25% of questions were targeted at A/A*, simply at i time 50% of questions inwards each newspaper are targeted at the equivalent grades, 7–9" reminded me of the pregnant stride upward inwards difficulty of the novel GCSEs.
Information nearly the Common Errors Made past times Maths Teachers and You Say Zero, I Say Nought.

Two weeks until #mathsconf6!

I'll piece of job out yous amongst this lovely tweet from @CDawson18:

5 Maths Gems #81

Happy New Year! Welcome to my 81^st gems post. This is where I portion roughly of the latest news, ideas in addition to resources for maths teachers.

1. Number Properties
In Gems 79 I shared this lovely puzzle from Chris Smith (@aap03102):

Since in addition to then I've seen 2 peachy resources based on a similar idea. The commencement is the interactive 'Consecutive Number Types' puzzles from Jonathan Hall (@StudyMaths):

And the minute is this complimentary worksheet 'Consecutive Chains' from MathsPad.

I recall these would locomote actually good at Key Stage 2, iii or 4 for exploring issue properties.

2. Online Textbooks
After I blogged almost a 1950s textbook final month, I gathered together a grouping of volunteers to type upwards former algebra exercises into Word in addition to locomote out the answers. Thank y'all thus much to everyone who has contributed. The projection is ongoing in addition to I volition spider web log almost it soon. In the meantime, y'all tin come across our progress here. Also, give cheers y'all to @EmporiumMaths for sharing roughly 1950s algebra questions from past times London O flat papers here.

Huge cheers to @NetNym for sharing a beautiful Victorian maths textbook 'Elementary Algebra for Schools' that has been fully digitised. This actually is lovely in addition to good worth looking through (I'm a chip addicted to it!). The zoom business office plant good thus the exercises tin hold upwards used inwards degree if desired - answers are included, in addition to the whole mass tin hold upwards downloaded every bit a PDF.

I recall that nosotros bring a lot to larn from the explanations in addition to examples inwards this textbook. I've started writing a post almost this which I promise to break adjacent week.

Meanwhile, a instructor inwards Commonwealth of Australia (@adaprojectnet) has created a website adaproject.net which is an opened upwards online textbook for all to use, roofing topics from Key Stage 1 to 5. It's worth having a await at this projection which is growing all the time.

3. Primary Resources

It's peachy to come across John Corbett (@Corbettmaths) publishing lots of novel primary 5-a-day content amongst his real pop GCSE 5-a-day collection. Each twenty-four hr catamenia at that spot are v KS2 SATs trend questions at 4 dissimilar hard levels.

Also for primaries, Dr Frost (@DrFrostMaths) has right away added Primary Maths Challenge questions to his website with the aid of @Mathematical_A. You tin browse past times theme or past times paper.

Primary Maths Challenge questions

4. Influenza A virus subtype H5N1 Level Resources
StudyWell (@_StudyWell) has published a twosome of practice papers for the novel Influenza A virus subtype H5N1 flat - these are complimentary for a express time.

You tin read the latest eNews from the Mathematical Association here.

I'm excited that I've right away booked a identify at post almost it. The cost goes upwards afterwards 31st Jan thus mass quickly!

I besides promise to come across lots of y'all at #mathsconf14 inwards Kettering on Sabbatum tenth March, in addition to for drinks the black before. I had a wonderful fourth dimension at all the maths events I attended inwards 2017 - if you've non been to a maths conference before, why non bring a become inwards 2018? All events are listed here.

I'll acquire out y'all with this lovely graph, shared by @simongerman600, showing what people actually hateful when they purpose vague terminology describing the likelihood of an event. There are other cool graphs here. I recall this 1 would brand an fantabulous give-and-take indicate when teaching probability.

Have a fantastic term maths teachers! And all the best for 2018.

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.
