How to help with this skill

Third graders begin to use multiplication, division, fractions and measurement regularly. Discuss which operation fits the question.

  • Label length and width clearly.
  • Multiply length by width for a rectangle’s area.
  • Add all four sides, or calculate 2 × (length + width), for perimeter.

Try this: Trace the edge of a book for perimeter and cover its surface with squares for area.
