Secret Word Addition with Hospital Things — Grade 1

This Grade 1 worksheet hides a word behind a code. A legend gives each of the beds, bandages and a stethoscope a secret number; the child decodes and adds each row of three or more pictures, and every total points to a letter — solve them all and the answers spell a hidden word. The addition is the real task, but the word at the end is the reward that keeps a child decoding. Totals stay within twenty so each sum can be checked by counting.

Because each total maps to a letter, a child has a built-in check: if the word does not make sense, a sum needs another look. That self-correcting quality suits Grade 1 well, and it sits on top of genuine practice — substituting picture-values and adding several of them, all kept within twenty so the sums stay countable.

Children who like hospital things keep going just to see the hidden word appear, which makes the adding feel like a game. When this feels easy, spell a new word in secret word addition with kitchen tools, or try secret word addition with space.
