Number Lines

Number lines are a specific type of visual representation. They can be used to enhance students' visual reasoning with numbers and investigate a variety of numerical relationships. In addition to comparing rational numbers, students in the middle grades can also use the number line to understand the value of and density of numbers between various units.
