Year 2 - Maths Learning - 3rd November 2017

This week we have been subtracting!  We have looked at three methods for subtracting two-digit and one digit numbers. 
1.  Counting backwards, either with objects or on a number line:

2.  Partitioning to subtract:

3. The vertical method:

The next step is to be able to use these methods when solving problems to help speed up the process.  A quick game to play at home.  Start with 20 (or more) counters each.  Take it in turn to role a dice, you take that number away from your pile.  The first to zero wins.  You have to say how many counters you have left after each turn.
