About this worksheet

This Grade 3 math worksheet gives focused practice with perimeter word problems using short, self-checking problems. The Grade 3 reference book revisits the skill through models, equations, and word problems, so this page rotates across direct calculation, reasoning, visual interpretation, and explanation prompts. Students should read what the question asks before choosing an operation or model. Each level has its own questions: support versions use friendlier numbers and three answer choices, standard versions work at grade level, and challenge versions add two-step and reasoning questions.

Encourage children to write or say the equation that matches the story, then check whether the answer fits the context. The goal is not just getting a number; it is explaining why that number answers the particular Grade 3 problem. Each item keeps the standard narrow enough for practice while still using varied situations so the page does not feel like one repeated drill.
