Estimating is an essential skill used in everyday life. This presentation explains how to apply prior knowledge about rounding numbers to estimating sums and differences. Example problems and assessment include large numbers, making this...

First graders practice rounding 4 digit numbers using place value concepts. In this estimating sums and differences lesson, 1st graders explore clustering, rounding, and front end estimation as methods for rounding decimals.

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate...

Students explore the concepts of estimating and rounding. In this estimating and rounding lesson, students play a game of tic-tac-toe. Students pick items and must estimate their cost by rounding. Students estimate the costs of pretend...

Second graders become familiar with need strategies for computation of money problems and estimating sums. In this computation lesson, 2nd graders solve real life problems to understand estimation and money problems.

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Help pupils explore estimation. They will make estimates and discuss when you might use an estimate. Then they discuss if their estimates are reasonable.

Reinforce estimation and the four operations—addition, subtraction, multiplication, and division—with eight page, 15 problem independent practice exercise.

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.
