Secondary Maths Collection – Tarsia - Number

TES Secondary maths resource collections

Collection Author: Craig Barton - Maths AST and creator of (TES Name: mrbartonmaths)

I have uploaded around 450 Tarsia activities to TES that I have either created myself or which have been kindly donated to my website. It is a wonderful piece of free software that has the potential to be an incredibly powerful teaching and learning resource. Tarsia activities can consolidate understanding, unearth nasty misconceptions, be engaging and promote positive co-operative learning and group work in the classroom. They are flexible, can be edited to suit your needs, and I would argue that they could be used with all ages and abilities for most mathematics topics.

The Tarisa Introduction Collection provides information on how to download the software and offers suggestions for how the resources might be used in the classroom – including a few twists!

Below are some of my favourite Tarsia resources for aiding the teaching and learning of Number at Key Stage 3 and 4. I hope you enjoy them!
