Common misconception
Children may not grasp why 5 + 5 is equal to 2 × 5
Continue to use the stem sentences to help children understand doubling; 5 + 5 is the same as 2 groups of 5. This is the same as 2 × 5. Children can use a 2 times table chart to help them answer questions.
At this point, children know doubling as an additive structure. They will now be able to represent a doubles addition equation as a multiplication equation. Remind children that doubling is the same as multiplying by 2
