Explain How To Add

Worksheet Description

This worksheet is a mathematical resource designed to enhance students’ understanding of addition using number lines. It features three number lines each extending from 0 to 20, with blue arcs indicating addition steps. The students are instructed to observe the number of jumps represented by the arcs and determine the missing numbers in the addition equations provided below the number lines. It is a visual approach to solving addition problems, with spaces provided for students to fill in the missing addends and sums.

The worksheet is intended to teach students the concept of addition through visualization and to reinforce their ability to infer missing numerical values. By engaging with this worksheet, students learn to translate the visual information of arcs representing jumps on the number line into concrete numbers. This activity is critical for developing an understanding of how numbers can be combined through addition and for building the ability to solve for unknowns in mathematical equations. It also aids in improving the students’ counting skills and their familiarity with number sequencing up to 20.
