Finding the difference.

This week in maths we have been doing some really tricky number work.  We have been learning to find the difference between two numbers by counting on, and also finding how many fewer one number is than another, by counting back.

We know it is important to learn this skill so that we can tell the difference between the values of our Skylander Giant's powers, so that we can tell how many fewer seats need putting out for school dinners than for sandwiches, and to help us play games like dominoes.
