What you need:
- A calculator
What to do:
Use a calculator to challenge each other to make number pairs that add to one thousand.
- Enter a three digit number that is a multiple of 100 into the calculator. For example, 400.
- Challenge the other player to make the number into one thousand using just one other number. In the above example the child needs to enter “+ 600=” to make one thousand.
- Take turns entering numbers and completing the challenge using many different three digit numbers.
What to expect your child to do:
- Use the facts to ten that they know to help them work out facts to 1000. For example, if you know 2 + 8 = 10, you can use this to work out 200 + 800 = 1000.
