Quick overview

This free area and perimeter worksheet for grades 3-4 helps students compare space inside and distance around.

Lesson plan snapshot

12-18 min
  • Warm-up (3 min): review multiplication facts.
  • Model (5 min): solve the worked example together.
  • Guided practice (4 min): complete problems 1-4 as a group.
  • Independent practice (6 min): finish the remaining problems.

Materials: grid paper, pencil

Learning targets

  • Calculate area by multiplying length and width.
  • Calculate perimeter by adding side lengths.
  • Compare area and perimeter for rectangles.

Step-by-step approach

  1. 1Identify the length and width of the shape.
  2. 2Multiply length × width for area.
  3. 3Add all side lengths for perimeter.
  4. 4Label answers with square units or units.

Common mistakes

Mistake

Mixing up area and perimeter formulas.

Try instead

Area counts square units inside; perimeter is the boundary.

Mistake

Forgetting to multiply for area.

Try instead

Count rows and columns, then multiply.

Mistake

Missing a side when adding perimeter.

Try instead

Add all four sides or use 2L + 2W.

Worked example

Guided
A rectangle has length 6 and width 4. Find the area and perimeter.
  1. Area: 6 × 4 = 24 square units.
  2. Perimeter: 6 + 4 + 6 + 4 = 20 units.
Answer: Area = 24 square units, Perimeter = 20 units
