These PowerPoint presentations are designed to introduce the concepts and vocabulary of halving even numbers to 10 by either splitting or sharing the set. The splitting PP also looks at what happens when you try to split an odd number. The doubling PP covers doubling numbers up to 10 by combining two identical sets to find a total.
