Adding Integers on the Number Line by Barbara Lichtenegger
Loading the math board and drawing, please wait…
This example visualizes the addition of integers on the number line using arrows and a moving bunny. It involves the core mathematical concept of integer addition and its representation on the number line. Using the Vector and Segment commands, arrows and line segments are constructed to illustrate the addition process. Suitable for high-grade elementary or junior high school students to learn the concept of integer addition.
