What you’ll learn

  1. Putting Groups TogetherUnderstand that adding means putting two groups together, and count to find the total.Adding is putting two groups together to make one bigger group. We pushed 2 red apples and 3 green apples together and counted them all: 5! The number we get when we count everything is called the total. You can add apples, toys, blocks — anything you can count.
  2. More Friends Join InAct out and solve 'add to' situations where more things join a group.Adding also happens when more things join a group. Three friends were playing, 2 more joined, and we counted on: 4, 5 — five friends! One more bird landing or one more block on the tower is adding too. When more join in, the group gets bigger.
  3. Count It AllUse fingers and objects to put groups together, count the total, and say it out loud.To add, put the groups together and count every single one. Fingers make great counters: 2 fingers and 2 fingers make 4. The last step is saying the total out loud, like '3 and 2 make 5!' Now you can add groups of anything you find.
