Math Puzzle with Insects and Bugs — Grade 2

A Grade 2 picture puzzle built on two-digit math: a picture of bugs comes in pieces, each holding an add-or-subtract-within-100 equation. Solving the within-100 problems reassembles the picture. Practising numbers up to 100 — the two-digit sums and differences of 2nd grade — is the work, and the puzzle turns each solved equation into a piece of a picture a child completes.

Second graders practise adding and subtracting within 100 — two-digit problems that build on earlier number facts. This puzzle turns that practice into picture-building: each piece of a bugs picture carries a within-100 equation. Solving the two-digit problems to complete the picture keeps the numbers-to-100 work concrete and motivating, the core of 2nd-grade base ten.

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 musical instruments, or try math puzzle with post office. 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.
