Counting DAILY  Present the 100 square splat grid http://www.primarygames.co.uk/pg2/splat/splatsq100.html Counting in 2s 5’s and 10’s to  Forwards  Backwards  Starting from different numbers, including 0  One more one less 

For the next 3 days children build on the language of subtraction, recognising and using the subtraction symbol within 20. The use of zero is important so children know that when nothing is taken away, the start number remains the same or when the whole group is taken away, there will be nothing left. They will also use the part-whole model alongside practical equipment to reinforce number bonds within 20. Remind children that subtraction can not be done in any order (not commutative), the largest number comes first. It is important that you discuss the symbol for subtraction.
