Resulting Sum

Worksheet Description

This worksheet consists of a series of arithmetic problems designed to be solved by applying the associative property of addition. Each question is structured with three numbers, two of which are grouped in parentheses, and a third which is to be added after the initial sum. The students are prompted to re-group the numbers to simplify the addition process, by associating different numbers together. The layout includes blank lines for students to write the results of their calculations after using the associative property to rearrange and combine the numbers effectively.

The objective of this worksheet is to teach students the associative property of addition, which states that the way in which numbers are grouped in an addition problem does not change the sum. By practicing with these problems, students learn to manipulate and combine numbers for easier mental addition. The worksheet encourages the development of flexible thinking about numbers, an essential skill for more advanced mathematics. It aims to build confidence in students’ ability to solve addition problems by finding the most straightforward sums first.
