Doubles to 20

Goal: Make doubles up to 10 + 10 with fingers and objects, and check a double by sharing it into two equal groups.

For parents: A double is a number added to itself, such as 4 + 4 = 8. Doubles are useful facts for other sums. Build each double with objects and let your child count to check. Begin with doubles to 5 + 5, and move on to doubles up to 10 + 10 when these feel easy.

Do together

  1. Same on both hands

    You need: Your hands

    Show the same number of fingers on each hand, such as three and three. Your child copies you and counts all the fingers: 'Three and three make six. Double three is six.' Try each double up to five and five. Then your child shows one for you to name.

  2. Build it twice

    You need: Twenty large paper squares torn by an adult, and two sheets of paper

    Put six squares on one sheet. Your child puts the same number on the other sheet, matching them in pairs. Count all the squares: double six is twelve. Write 6 + 6 = 12 together. Build other doubles up to ten and ten, and keep a list of the ones you make.

  3. Share it back

    You need: The paper squares and the two sheets

    Choose a double you have made, such as eight squares. Your child shares them one at a time onto the two sheets until none are left. Are both groups the same? Four and four make eight, so double four is eight. Try another double and check it by sharing.

Talk about it

  • What is double four, and how can we check?
  • Which doubles do you know without counting?
  • If we share ten into two equal groups, how many are in each?
