Secret Word Addition with Musical Instruments — Grade 1

A secret word waits at the bottom of this sheet. The legend turns each of the drums, bells and a flute into a number; the child adds three or more picture-numbers per row, and each answer reveals a letter to spell the word. The decoding-and-adding is the work; the word is the reason to finish. Practising several-addend addition is what makes it Grade 1, and within-twenty totals keep every sum a child can check by counting.

The mystery word rewards persistence: a child must solve every row to read the message, which means practising multi-number addition many times over. That repetition — adding three or more values within twenty — is exactly what builds Grade 1 confidence, and the spelled word makes the repetition feel like a game rather than a drill.

Children who like musical instruments keep going just to see the hidden word appear, which makes the adding feel like a game.
