Scrambler Size Sort Activity

As part of B's pre-maths skills we have been using these kinds of activities to work on size discrimination.  One problem is explaining what he has to do - after big little and middle sized I kind of run out of vocabulary! Bob the Builder being one of his favourite characters I found and printed this Scrambler size sort from Tired Need Sleep.  B was not into having photos taken of these and kept scooping them up to take them away so here is part of one very dodgy photo just in case you don't know who Scrambler is (Bob the Builder would be horrified ;) ) there are actually 8 shapes.
