How to play
A nature park needs its gardens fenced (perimeter) and its plots measured (area). Each round draws a shape on the ranger's map — a rectangle at first, then L, T and U shapes — and asks for either its perimeter or its area. Tap one of the four wooden tiles to answer. Get it right and the fence traces itself in gold around the edge, or the plot fills in square by square, so your child sees exactly what was counted. Every third correct answer brings a new animal into the park, and twelve correct answers complete the patrol. Three wrong answers end the round.
What your child will learn
- Identify and classify 2D shapes
- Measure perimeter and area
Skills practiced
- Spatial reasoning
- Measurement
Why this age range
Tuned for grades 3–4. Younger children find the unit-tile counting tedious; older children breeze through and want algebraic shortcuts the game doesn't offer. The grade-3 and grade-4 standards specifically call out perimeter and area as distinct concepts, and the game tracks that distinction.

Notes for parents
The classic mistake on this topic — confusing perimeter with area — happens because both are taught the same week with the same rectangles. Perimeter Patrol separates them clearly. Perimeter is fences (a length); area is tiles (a coverage). Once your child has felt the difference in this game, they're far less likely to mix them up on a test.
