Multiple Representations: Number Line
Overview
Easy access to seeing the relationships between numbers promotes Number Sense as students see these connections repeatedly. Students can also use number lines to practice and demonstrate their approaches for solving problems involving Proportional Reasoning, such as fractions and ratios, and exploring Operations with positive and negative integers.
