mathematics teaching 10 ~ 16

Monday, 16 February 2015


these resources are based on Dave Hewitt's erudite work

there are youtube videos demonstrating uses of his software Grid Algebra:
the unplugged, 'tapping' version of this task is used here for work on expressions and simplification
it can also be used for quick number and  algebra practice and is simple enough to set up

some work needs to be done on analysing why a large expression can be reduced to a much simpler one
