My daughter needed help with adding and subtracting numbers up to ten. This is what we did, based on suggestions from her class teacher.
Ingredients
Ten chess pieces: five black, five white
Coloured felt pens
Exercise book
3 + 2 or 5 -2'Well done' stickers
Total Time: 40 minutes

1. Set out five chess pieces and put two on one side. Ask 'how many do I have' if I add 'one', 'two' then 'three'. Then set out some sums - 2+1=, 2+2=, 2+3= in the exercise book.

What next?


10 - 3 or 5 + 210 - 1 or 5 + 410 -2 or 5 + 3

2. Set out five black pieces in a row. 'Take away' one, then two, then three etc, asking each time, 'how many do I have?' Then set these out as sums, making sure to explain what the minus or subtract sign means.


3. Now, put a row of five white next to the row of black. Repeat the exercises in a similar pattern for adding up to ten or less, and subtracting from ten.
5 + 1 =        10 - 1 =
5 + 2 =        10 - 2 =
5 + 3 =        10 - 3 =
5 + 4 =        10 - 4 =
5 + 5 =        10 - 5 =
etc

4. When we'd done, her book looked like this:


We made a number spider (above right) 1+9 = 2+8 = 3+7 = 4+6 = 5+5 = 10. Then we drew the pairs of numbers that add up to ten (as shown below) and my daughter coloured it in.
