Solve Problems by Estimating

Learners can use estimation in all computation activities to estimate answers in advance, or to evaluate how reasonable an answer is. See Use Estimating Skills for tips about how and when to estimate. Use the following activities in Math Skill Builders: Whole Number Arithmetic to practice using estimation skills.

In Tutor, learners can estimate the answer and then watch the demonstration to see how close the estimation was to the correct answer.

In Practice and Assignment, learners can solve the problems, then estimate the answer to make sure their answers makes sense, before they check each problem.
