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...

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.

In this estimating products worksheet, students practice their large number multiplication skills as well as their rounding abilities. They are also challenged with word problems and a table.

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.

For this estimating products and quotients worksheet, students estimate each product or quotient and identify the method they used to solve the problems. Students finish with two test prep questions using estimation.

Students investigate estimating products. In this multiplication lesson, students discover the rules for rounding numbers up to the ten thousands place value.  Students compare the actual product to the estimated product.

Know if the product is not correct. Pupils learn a quick check to see if a product is incorrect. The video uses the value of the units to check solutions to multi-digit multiplication problems. Two short worksheets allow learners to...

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...
