Quick overview

This free geometry worksheet for grades 2-4 covers shapes, perimeter, and area basics.

Lesson plan snapshot

15-20 min
  • Warm-up (3 min): identify shapes and their sides.
  • Model (5 min): solve the worked example together.
  • Guided practice (5 min): complete problems 1-3 as a group.
  • Independent practice (7 min): finish the remaining problems.

Materials: grid paper, pencil

Learning targets

  • Name and describe basic shapes.
  • Find perimeter by adding side lengths.
  • Understand area as covering space with square units.

Step-by-step approach

  1. 1Count sides and corners to identify the shape.
  2. 2Add all side lengths to find perimeter.
  3. 3Use rows and columns of squares to find area.
  4. 4Label units for every answer.

Common mistakes

Mistake

Mixing up perimeter and area.

Try instead

Perimeter is the distance around; area is the space inside.

Mistake

Forgetting units.

Try instead

Always include units like cm or square units.

Mistake

Counting squares incorrectly.

Try instead

Count rows and columns, then multiply.

Worked example

Guided
Find the perimeter of a rectangle with sides 5 and 3.
  1. Perimeter is the sum of all sides.
  2. 5 + 3 + 5 + 3 = 16.
Answer: 16 units
