Doubling is known as 'twice as many.' We can describe that to the children when we are talking to them about doubling. Children need to start to understand doubles as learning doubles can help us with knowing different addition facts. If we know 2+2 is four, it is easier to know 2+3 has to be 5. It is also the first steps in learning to multiply ( ie 2 lots of). Give your child lots of time to play with doubles this week with the following activities.
1. Dice doubles.
Play a game of doubles with the dice. Can they roll a double? What does that mean? If they do roll a double, how many do they have altogether? Can they say this as a number fact? double six is 12. six and six is 12. Can they write this as a number sentence?
If your child does not roll a double, can they identify this? How do they know that it is not a double?
They can still work out how many they got altoghether! How about turning into a game and seeing who can get the first double or who can get the most altogether after 4 rolls each?
If you have a set of dominoes why not have a game and talk about the doubles when they pop up? Look at what they make altogether. Can your child recall the number fact?
3. Double the items.
Ask your child to sit opposite you. Use small items ( pebbles, pasta, small toys) and place an amount in front of you. Your child needs to make the double of that amount. You might also do this with your fingers.
Your child can record the number sentence they have made after each double.
4. Double hunt.
Give your child a number ( or a tower of bricks/ amount of sweeties! if you have them). Hide the corresponding double around the house. Your child needs to go on a double hunt to find the correct amount and then work out what double the amount is . Ask them to repeat the number fact back to you. Double 3 is 6. Double 4 is 8.
5. Make ladybirds/ butterflies/ fairy wings.
A good way to explore doubling is to look at symmetry. Ladybirds have spots. By putting so many spots on one side of the ladybird, your child has to put the same amount of spots on the other side and double the amount. Talk about how many you have altogether now. You can do the same with spots on butterfly wings or also fairy/ elf wings. Explore different double amounts.
