154 worksheets
Code-addition worksheets add a dash of mystery to early maths: a kindergartner solves small sums, and each answer maps to a letter that reveals a hidden word. For five- to seven-year-olds it pairs simple addition with the thrill of cracking a code, so number practice and letter recognition happen together. The sums stay small and picture-friendly so the puzzle is the reward, not a barrier. Each sheet is a free printable PDF with a matching play-online version that checks the sums and the revealed word, plus an answer key. The whole set is available in all 11 languages we publish in.
