Math Puzzle with Post Office — Grade 2

This Grade 2 math puzzle worksheet builds two-digit addition and subtraction within 100 into a picture of post. Each puzzle piece carries an equation, and solving it — adding or subtracting numbers up to 100 — shows where the piece belongs in the picture. That within-100 arithmetic, with the two-digit sums and differences second graders work on, turns number practice into a picture a child reassembles. It is 2.NBT.B.5 skill work in puzzle form.

Second grade is when children master adding and subtracting within 100, working with two-digit numbers. This puzzle of post 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 space, or try math puzzle with trees. 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.
