This week please practise number bonds to 10. Once the children have these securely in their minds it really helps speed up addition sums. The attached shell sheet can be used. Cut out the shells and then practise each day matching the 2 halves together. If you don't have a printer you can write the number pairs on paper and match them. Once you think your child knows their number bonds check by giving them a number and getting them to tell you its partner.
I have also included an ordering numbers to 20 sheet for your child to practise this skill. They can either stick the numbers down or place them in order then reuse them during the week. Again if you don't have a printer you can write the numbers on paper.
