Prime Path Math Activity

Students identify which numbers in a grid are prime versus composite.

Students apply the definition of a prime number repeatedly to trace a continuous path through a grid.

Students self-check their completed path against the included answer key.

The grid's first step is already solved as a model, so point it out before students start.

Since it is a single-page puzzle, use it as a warm-up, math-centre task, or early-finisher activity.

Use the coloured answer key to spot-check answers quickly, or project it for whole-class review.

Prime number identification — students distinguish primes from composites (such as recognizing 37 and 31 as prime while 30, 40 and 22 are not) to find the correct path.

Sequential logical reasoning — students trace an unbroken chain of adjacent prime cells, mentally backtracking when a path leads to a dead end.

Self-checking — students compare their traced path against the included answer key.
