What you’ll learn

Putting TogetherUnderstand addition as combining two groups to find the total.Adding means putting two groups together to see how many you have in all. The smaller groups are parts and the big group is the whole. After combining, you count everything. Adding always makes a group the same size or bigger, like 2 and 3 making 5.
More Join InRecognize 'add to' situations where more things join a group.Adding also happens when more things come along and join a group. If 3 children are playing and 2 more join, the group grows to 5. You can act out these stories to see the group get bigger, then count to find the total. Adding is all around us.
Saying the TotalFind and say the total (sum) when two groups are combined.The answer to an adding problem is called the total, or sum. Questions like 'how many in all?' or 'altogether?' are clues to add. By putting two groups together and counting, you can find totals like 2 and 3 making 5.
