How well can your child count in tens? Does your child know that rather than counting out from 1 to a hundred, they can easily count 100 boxes in stacks of tens? If your child is still a bit confused about how that works, use this easy worksheet to clear up their confusion. In the exercise, your child will have to count boxes of pineapples stacked in tens, to know which truck carries 100 pineapples. Ask them to circle the truck that carries 1 hundred pineapples.
