Description

Overview:
For many adult students, positive and negative integers are an example of when math “keeps changing the rules.” This is the fourth of six lessons guiding students in constructing the abstract concepts necessary to understand adding positive and negative integers.
This lesson will review previous knowledge about negative numbers and teach adding integers with the same sign. The previous lesson focused on “real life situations” and this will teach expressing those real life situations on a number line. The actual problems will still be adding integers of the same sign because of the prevalence of confusion with adding two negative numbers.

Opportunities for Deeper Learning: Strong (2)

1st/2 points: It is at the conclusion of the lesson where the author reveals the math rule. I have found that the rule reveal after the lesson prepares the students' brains for deeper understanding, versus, "here's the rule & how it works."
2nd/2 points: Author notes at conclusion of lesson, that using number lines are helpful, "but they would not be practical if we were adding very large numbers."
