I wrote a selection of PPoint slides for a range of topics last year. The slides each contain questions and often video links to news topics. They’re intended as 5 minute fillers – breaks from a main lesson task.

A cool visual application to see prime numbers and numbers as a sum of their prime factors in a different way.

A handy tool that decomposes numbers into their prime factors, and gives you a great visualisation of the process too. It makes for a great teacher demonstration, or just a quick checker for yourself! You can also use the ‘try yourself’ button to do it all on your own.

Did you know you can use prime factors to calculate square and cube roots (if they’re integers at least)? Now you do.

Here’s a handy worksheet to practise.

Today I presented at the West Yorkshire Teaching Alliance conference.

The session was about deeper understanding – specifically, the associative, distributive and commutative properties of multiplication.

Karen’s presentation is here: “deeper understanding” .

And her notes about the laws of multiplication are here

This one comes courtesy of the inspiring @HelenHindle1. It’s a great open lesson looking at patterns in the products of number factors.

Chances are, your students will surprise you, if you give them the opportunity.
