Y2 - Maths Learning - Week Beginning 7th November 2016

This week we have been looking at subtraction and how we can use counting backwards and our knowledge of tens and ones.  At home, try counting back in 10s from any two digit number: 84, 74, 64, 54 and so on.
Then extend to taking 30 or 40 from a two digit number: 87-30=
By counting back 3 tens from 87 you should get to the answer.
It is only a short step from here to using a formal method for subtraction.
