Improve eidetic memory
Submitted by Dave Clapham on 13 February 2006.
A simple idea that makes a great warm up exercise for any group. A series of smiley faces is portrayed in increasing numbers and grouped in different ways. Encourage students to say how many faces there are (ideally without counting – as the ability to make and interpret patterns helps with many aspects of maths) and discuss how they look at the patterns, chunk up into to 3s, 4s and 5s, etc.
