Numeracy activities for form or tutor time.
Here are some sample activities to promote numeracy in registration/tutor time. They were originally designed for mixed secondary vertical tutor groups, so should be as about as accessible as possible.
If you like them I have a lot more (about two years worth!) and can upload those too.
They all start with a group of rebus (catchphrase / SWYS) puzzles to get the students thinking. This works quite well as a hook and promotes a positive outlook toward doing *maths* in tutor time.
Cheers, hope they are useful.
