Math PK-2

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 Counting, Estimation, and Operations.

Use It in the Classroom

Watch how this elementary teacher explores a 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.

  • As a visual tool, number lines reinforce Counting sequences and Linearity, which are critical for addition and subtraction problems. Teachers can also display a large number line in the classroom to serve as a reference for students, alleviating some of the cognitive load on Working Memory.
  • Design It into Your Product

    Videos are chosen as examples of strategies in action. These choices are not endorsements of the products or evidence of use of research to develop the feature.

    Learn how Motion Math Zoom uses an interactive number line to teach 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 Counting and Place Value, in a visual, 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.
