Addition with Space — Kindergarten

Each problem on this sheet shows rockets, planets and a star to gather: one small group, a plus sign, another small group, and a box for how many in all. Because every one of the space things is right there to be touched and counted, even a child who is not yet reading can finish the whole sheet on their own. Counting two groups and saying how many altogether is the earliest, most concrete form of addition — the groundwork the written plus sign is built on later.

Before written sums make sense, addition has to happen with things a child can see and move. Joining a group of space things to another group and finding the total builds the part-and-whole idea — that two smaller amounts make one larger one — which is the concrete ground every later written method is built on.

Children who enjoy space take to this one quickly, and it works just as well as a quiet morning task or a count-along on the board. When the set feels easy, count a different collection in addition with thanksgiving, or try addition with vegetables.
