Lesson objective: Fluently compare integers using inequalities in real life situations.

This lesson helps to build fluency with integer comparison. A number line is used here because it highlights an integer's distance and direction from other integers and zero. This work develops students' understanding that there are three possible relationships between any two numbers, a and b (namely, a < b, a > b and a = b.

Students engage in Mathematical Practice 4 (Model with Mathematics) as they plot points on a number line to make comparisons between integers.
