What your learner will practice

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

With area & perimeter in Grade 3, the goal is to build understanding and to explain the method, not just get a number. Take breaks and repeat short sessions when needed.

How to solve area & perimeter problems

  1. 1Label length and width clearly.
  2. 2Multiply length by width for a rectangle’s area.
