Add integers on a number line
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to add integers on a number line.
In this lesson, we'll explore how to add integers on a number line. Mathematical thinking develops logical reasoning and problem-solving abilities.
A number line is a line with numbers marked at equal spaces. It helps us see the order of numbers and the distance between them. We can use a number line to count forward, count backward, add (move right), or subtract (move left). For example, to add 3 + 2, start at 3 and jump 2 spaces to the right—you land on 5! Number lines help us visualize numbers and operations.
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.

Use a number line to solve: 8 - 2 = ___
Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring add integers on a number line.
