Secret Code Addition with Clothes — Grade 1

Each row is a little cipher to solve by adding. The legend pairs every one of the clothes with a number; the child decodes a row of three or more pictures into numbers and totals them. Substitution plus adding several numbers is exactly the Grade 1 work here, and the code wrapper keeps a child decoding row after row. Sums stay within twenty so the answers remain something a child can check by counting.

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 clothes treat each row as a small puzzle, which keeps a code-breaker happily adding. When this feels easy, crack the code in secret code addition with desserts and sweets, or try secret code addition with fruits.
