Secret Code Addition with Furniture — Grade 1

Here addition wears a disguise. A legend assigns each of the furniture a number; the child reads each row of pictures, substitutes the numbers, and adds three or more of them together. The decoding gives a reason to keep going, but the real work is the multi-number addition that defines Grade 1. Every sum is held within twenty, so a child can fall back on counting to be sure the code came out right.

Looking up each picture's value and then adding three or more of them rehearses both careful reading and multi-number addition at once. For a Grade 1 child that combination builds real confidence with small sums, and holding every total within twenty keeps the work honest — a child can always count the decoded numbers to check the answer rather than guess it, then move on to the next coded row.

Children who like furniture treat each row as a small puzzle, which keeps a code-breaker happily adding.
