Subtracting Tens

Worksheet Description

This worksheet is designed to teach students the concept of estimation in addition by rounding numbers to the nearest ten before adding them. It contains a series of addition problems, each with two whole numbers that students are instructed to round to the nearest ten before summing. The structure of the worksheet is straightforward, with each problem clearly numbered, and space is provided for students to write the rounded numbers and the estimated sum.

The purpose of this worksheet is to help students develop their number sense and to understand that estimates can be useful for quick calculations that do not require exact answers. By rounding numbers to the nearest ten, students learn a practical approach to simplify calculations, which can be especially helpful in real-world scenarios where approximate answers are sufficient. The repetition of this process across different problems reinforces the skill and helps students become more confident in making mental calculations. The worksheet is likely targeted at elementary school students who are at the stage of learning basic arithmetic operations and the concept of rounding numbers.
