Identify & Sort Key Problem Solving Words

I have used this resource to good effect with my Lower Key Stage 2 class. This resource is differentiated - I gave my lower ability children just the addition and subtraction 'mat&' (with the appropriate words at the bottom of the doc) whereas my higher ability tried to identify words for all 4 operations. The PDF is printable and ready to go (and then be guillotined/cut!) and the MSWord is editable, if you want to add or adjust the words or mats.
