Add to 20

Worksheet Description

This worksheet is designed to help students practice addition with sums up to 20, using a number line as a visual guide. The sheet includes a series of addition problems such as “12 + 5”, “8 + 9”, “11 + 7”, and “15 + 5”, with a number line ranging from 0 to 20 provided for each problem. Students are expected to use these number lines to calculate the sums and write the answers in the blank boxes adjacent to each problem. The worksheet’s format is clear and straightforward, focusing on the use of the number line to solve each addition problem.

The worksheet’s objective is to teach students how to effectively use a number line for adding numbers, especially when dealing with larger sums that may be more challenging to compute mentally. It reinforces the concept that addition is a matter of counting forward from one number to reach another. This activity helps students to visually and practically understand how different numbers combine to make larger ones. Moreover, the exercise serves to strengthen their arithmetic skills, particularly their ability to perform addition operations that result in sums beyond the basic 1-10 range.
