Math Puzzle with Musical Instruments — Grade 2

Two-digit math, one picture: this Grade 2 worksheet builds addition and subtraction within 100 into a puzzle of instruments. Each piece is an equation; solving the within-100 problems shows where the pieces go. Practising numbers to 100 — the two-digit sums and differences second graders need — becomes the work of completing a picture. It is 2.NBT.B.5 add-and-subtract-within-100 skill in a puzzle a child enjoys.

By second grade, a child works with two-digit numbers — adding and subtracting within 100, sometimes regrouping tens and ones. This puzzle of instruments builds exactly that: each piece is a within-100 problem, and solving it advances the picture. Practising numbers to 100 this way keeps the two-digit arithmetic concrete, with a visible reward for every correct answer.

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 community helpers, or try math puzzle with space. 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.
