Id like to start some sort of maths intervention for a small group of my yr2's. They have poor short term memory, and struggle with basic number bonds, doubles/halves, one more/less, odds/evens etc. My TA will only have 10mins 3 times a week, so the activities need to be short but intense. Does anyone have any good suggestions/resources/schemes? Was looking at springboard but looks like its more aimed at ks2.
