Multiple Representations: Number Line


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.

Use It in the Classroom

Watch how this elementary teacher explores number line with her class by integrating it into her game board. Through probing questions, this teacher promotes the development of student Number Sense and linearity.

  • Teachers can display a large number line in the classroom to serve as a reference for students, alleviating some of the cognitive load on Working Memory. As a visual aid, teachers can also use number lines to reinforce proportional relationships, fractions, and ratios, which are critical to Proportional Reasoning and support understanding in pre-algebra as well.
  • Design It into Your Product

    Learn how Motion Math Zoom uses an interactive number line to teach a component of Number Sense, place value. Through this fun game, learners are able to play freely with space and quantity of concrete objects to develop their place value and magnitude understanding.

  • Products can design number lines that display abstract concepts, like plotting fractions and integers, in a visual and interactive manner to support student understanding. They can also provide the option for learners to show their work and thinking on a number line when solving problems.
