Expand on prior knowledge of place value to teach your class how to round whole numbers. This essential skill is explained with the help of a number line before introducing the explicit rules for rounding numbers up and down. Work...

Teach young mathematicians that sometimes just getting close to the exact answer is perfectly fine, by using this collection of estimation worksheets.

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Teach your class a thing or two about making educated mathematical guesses. Learners read a passage that explains estimation and approximate and exact answers. They then respond to five questions about and related to the text.

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes...

What is your favorite animal at the zoo? Young mathematicians answer eight multiple choice questions, based on a survey of 50 people presented in a pie graph. Additionally, the graph does not display any numbers, but rather...

Investigate the relationship between irrational roots and a number line with a resource that asks learners to put together a number line using radical intervals rather than integers. A great progression, they build on their understanding...

Come take a ride on the space bus! Scholars go on an imaginary trip to pick up their peers from the inner and outer planets while reinforcing math skills. First, learners round decimals to identify each planets' distance from Earth....

This activitiy asks students to randomly select a one-digit divisor and a three-digit dividend and estimate the quotient mentally. Students must then explain why they believe their estimate is accurate.
