This week we are going to be learning about doubling. The children will learn that double means ‘twice as many.’ They should be given lots of opportunities to build doubles using real objects and mathematical equipment if you have any e.g. dominoes. Building numbers using the pairwise patterns on 10 frames also helps children to see doubles. Mirrors are also a fun way for children to ‘double’ the quantities they build. Encourage the children to say the doubles as they make them e.g. Double 2 is 4.
Introduce the new mathematical word of the week - Doubles. Explain that doubling is when you add the same number to itself so you have ‘twice as many.’ - Provide examples using fingers e.g. Hold up 3 fingers, model doubling 3 by holding up 3 on other hand - ask children to tell you the answer. Repeat with other examples between 0-5. What would you need to do if you double 6 or higher? Do you have enough fingers?
Explore doubling visually through ‘The Story of Doubling’ PowerPoint which is attached below. Afterwards, place a range of number cards on the floor between 0-10. Can your child select a card, count out the correct number of objects and then double it? Try to represent your doubling through pictorial representations, or if able to, you could write your doubles as a number sentence!
Revise yesterday’s new maths word - Doubling. Can you explain to your adult what this means?
Provide a set of dominoes and ask the children to sort the dominoes between doubles and non-doubles. Ask the children to explain either why they are/are not a double. Work together to play dominoes and look at the doubles they make as they play.
Play Doubles! The children take turns to roll two dice and score a point each time they make a double. The first to reach 5 points wins!

Create some number dot cards and hide them outside in the garden. Choose a number e.g. 4. Can your child search the garden to find the two cards which have four dots on to make the double! Once you find one, represent your doubles either pictorially or as a number sentence too.
Provide a ladybird or butterfly template and ask the children to make doubles by adding the same number to each side. How many different doubles can you make? Can they make one which is not a double and tell you why? You could paint your doubles, use buttons or pom poms to represent, or draw you doubles. Once finished, try to represent your doubles as a number sentence too.
Double Hit! Chalk some numbers on the ground or attach the numbers to a fence. Call out a number e.g. 2. Can you find the answer to the double and hit the correct number with a ball?
Doubles Dance - Write doubling number sentences on post-it notes or on small pieces of paper e.g. 5+5=. Then write the answers on separate post-it notes.paper. Place the number sentences and the answers on the floor. Play some music and ask your child to see how many doubles number sentences they can solve before the music ends by covering the number sentences with the answer.
