Secret Code Addition Worksheet
Secret Code Addition with Faces (Black & White) — Grade 1
This is addition as code-breaking. The smiling faces, winking faces and a yawning face each carry a hidden value from the legend, and each row strings three or more of them into a sum. The child looks up every picture, writes its number, and adds — practising the several-addend addition that is new at Grade 1. Because the totals never pass twenty, the puzzle stays within reach: a child can always count to confirm the decoded answer.
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 faces (black & white) 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 forest creatures, or try secret code addition with kitchen tools.
