always and never

these resources are adapted from an idea from mathspad.co.uk
which has a helpful collection of resources (some free)
for example, the substitution game seems a very good idea



place each of the 20 expressions in an appropriate column



students could be given 9 expressions to place in correct places
or (maybe better)
they can be asked to think about appropriate expressions themselves
