When I need some practice material for pupils then
@draustinmaths.com is so useful. Easy to find the appropriate resource as it is well-labelled/grouped - answers/solutions are given. Load it all up into a Zoom whiteboard and off we go. Huge 'Thank You' to Amanda @draustinmaths.com

Jemma @jemmaths.bsky.social did such a great thread on Twitter in 2022 that I wanted to put it together and share it with teachers. You can pause it wherever you want for individual or group discussion. Not new but worth a repost. youtu.be/YBx1rcPjuck?...

Great to meet with OCR staff Amy Dai @miss-agd.bsky.social Sarah Gotting and Mary Fisher online yesterday to discuss the feasibility of 'maths mastery' approaches, including manipulatives and bar models, being integrated into GCSE maths examinations. Lots of issues with this and much to discuss...

1/n Thought we had done our last Jinja Educational Trust (JET) trip, but they persuaded me and Karen to go again. We have spent the week travelling into JET schools, some 'off road' a long way from Jinja. Lots to share: children are stunning - so calm, focussed and well-behaved.

This is still one of my favourite videos I have made. A presentation I did for @lasalleed.bsky.social in 2023. Using @mathspadjames.bsky.social Decimals Blocks app. Fractals in action. I love apps that enable users to zoom in and out and to appreciate scale and connections.

Huge shout out to @draustinmaths.com for her resources free online. These were so useful for Y10 consolidation and practice this week. They are so well constructed 😍

Great question from a Singapore Maths competition for Primary 6. Requires a careful and systematic approach and also has triangular numbers within that analysis.😍

Great problem solving for Y3 and Y4 pupils. I also use some of these questions for my Y2 Maths Enrichment Club.

‘Learning that does not last was never really learning, it was mere exposure’. Another cracker from @markmccourt.bsky.social. In my role as an intervention teacher and as a tutor preparing pupils for GCSE I see this issue day in, day out.

It has been interesting helping some of our Y3 and Y4 pupils look at ways of solving these sorts of problems - this one is taken from a Grade 3 international maths competition.

Very excited to be asked to go out to Uganda this summer holiday to help the Jinja Educational Trust jinjaedtrust.com once again. They have recently taken on several new schools, so there is an increased need for support and training. Just booked flights 😁

The disastrous periodic 'revolution' so beloved of snake oil salesmen i.e. politicians et al desperate to leave a legacy - which they do, but mostly not in a good way 😱 - as opposed to the careful 'evolution' model of other successful jurisdictions. As always, Mark hits the nail bang on the head!

(1) When we first introduced the Singapore maths pedagogy into our school in 2006, we realised very quickly how we needed to concretise the 'groups' in 'groups and items' as bits of paper. This made the groups something distinct from the items and they could be manipulated.

The words of a wise man who knows a LOT about teaching and learning.Too often I see an overcrowded maths programme being gone through at a ridiculous pace leaving many pupils trailing in its wake.

Working with Y3 and Y4 Maths Clubs this week: as well as some UK First Maths Challenge questions, I will also share some Grade 2 and 3 problems from Singapore Maths competitions such as these: Grade 2 then Grade 3 - medium difficulty from the middle section of the papers. #UKMathsChat #MathsToday

Working with some of our Y2 pupils this week on problem solving. Used some questions from the
@mathematicala.bsky.social First Maths Challenge. We could have used the answers given, or trial and improvement, but instead we built on their knowledge of bar models, and number rods. Polypad app.
