Estimating Products

Multiplication on the fly becomes easy with the magic of estimating! Scholars round numbers up to four digits to complete multiplication problems without a calculator. They write in the new factors and the approximate product for the...

Class members come up with a hypothesis on the number of decimal digits in the product of two decimals. Learners work in groups to complete several decimal multiplication problems. The results help groups develop a conjecture on the...

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

In this estimating products activity, students review the two steps for estimating products using whole numbers and decimal numbers. Students first round each number and multiply the rounded numbers.

In this estimating products worksheet, students use the methods for estimating products to solve the five word problems. Students show their work.

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

Teach children that going to the circus isn't all about clowning around with this lesson on multiplication. Focusing on a series of three circus-themed word problems, students practice creating area models as a tool for finding products...

Fifth graders demonstrate how to estimate products. In this estimation lesson, 5th graders participate in an estimation drill and are introduced to the steps of estimating a product. Students practice rounding the numbers and then...

In this estimating products worksheet, students solve 13 problems in which each factor is first rounded to the greatest place. Students then estimate the each product.

Estimation is as easy as one, two, and three. Scholars use an interactive to estimate in one, two, and three dimensions. They must determine the number of smaller segments, polygons, or solids that fit into longer segments, polygons, or...
