Add integers with the same sign
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to add integers with the same sign.
In this lesson, we'll explore how to add integers with the same sign. Mathematical thinking develops logical reasoning and problem-solving abilities.
Integers are whole numbers and their opposites: ...-3, -2, -1, 0, 1, 2, 3... Negative numbers are less than zero and are used for temperatures below freezing, debts, elevations below sea level, and more. Positive numbers are greater than zero. Zero is neither positive nor negative. On a number line, negatives are to the left of zero, positives to the right. Understanding integers expands the number system beyond counting numbers!
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.

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 with the same sign.
