For example
Six sweets becoming twelve is doubling, twice what you started with.
In Grade 2
Children make a matching set beside the first one and count them all, seeing doubling as adding the same amount again.
Watch out for
Children often add two rather than double. Doubling six gives twelve, not eight.
Say it at home
Say a small number and ask your child to double it, then count out the objects to check.
