Math Puzzle with Hospital Things — Grade 2

This Grade 2 math puzzle turns two-digit addition and subtraction into a picture of hospital things. Every piece holds a problem within 100, and solving it places the piece. Working with numbers to 100 — two-digit sums and differences, sometimes with regrouping — is exactly the 2nd-grade base-ten practice this sheet builds, and reassembling the picture makes the arithmetic feel like play. A child solves, places, and completes.

Second grade is when children master adding and subtracting within 100, working with two-digit numbers. This puzzle of hospital things builds that mastery piece by piece — each within-100 equation solved fits another part of the picture. Practising numbers to 100 with a visible payoff keeps the two-digit arithmetic lively, the genuine 2.NBT skill behind the play.

Children enjoy watching the picture come together as they solve each problem, and a finished math puzzle is a satisfying proof of within-100 skill. When this is easy, solve the puzzle in math puzzle with insects and bugs, or try math puzzle with pets. You can also browse every Grade 2 math puzzle or the whole second-grade collection — each sheet prints cleanly or plays online for free, and the more within-100 problems a child solves, the surer their two-digit addition and subtraction grows, one solved piece at a time.
