WELCOME

 This lesson includes all that you need to help year 1 children to find with half of objects, shapes or half of a collection (amount). 

 In this power point, we will learn how to find half of an object or shape as well as half of a set of objects or an amount.

To find half of a group of objects, we need to divide the group into two equal parts.  For example, to find half of 12 lollies, we need to split them into two equal groups.  Each group needs to contain the same number of candies.  The groups are equal.  Each group contain 6 lollies.  So, half of twelve is six. 

Similarly, to find half of 20 balloons, we need to divide them into two equal parts.  Each group is now a half.  There are 20 balloons.  We divided them into two equal groups.  Half of 20 is 10.
