50 Open-Ended Maths Challenges

We’ve all had maths lessons where we’ve planned a 20-minute activity and the class genius completes it in 2.
We’ve all desperately needed a ‘filler’ activity when that assembly gets cancelled.
We’ve all needed a straightforward task to set as cover work.

This book contains 50 open-ended maths investigations that work very well as either extension activities or for whole class lessons.
