What your learner will practice
Multi-step thinking. Fourth graders practice larger numbers, fractions, decimals and multi-step reasoning. Encourage estimation as a way to check answers.
With factors & multiples in Grade 4, the goal is to build understanding and to explain the method, not just get a number. Take breaks and repeat short sessions when needed.
