Grades: K‒4

Students control the jumps of a rabbit along a number line. The rabbit can make jumps of two different integer distances, and these distances can be changed by you or your students. The rabbit might, for example, be limited to jumps of 1 and 2, or it might be able to take jumps of 10 and –3. Don’t be fooled be the cuteness of the rabbit: The range of questions that can be explored with this activity run from very simple to quite challenging!

OBJECTIVES

Note: The Sketchpad model that accompanies this activity can be used in a variety of ways. The objectives below compile the learning outcomes across the suite of ideas presented in these notes. Depending on the grade you teach, you should touch upon only those objectives that are developmentally appropriate for your class.

- Students will use a number line model to explore properties of positive and negative numbers.
- Students will use a number line model to explore properties of even and odd numbers.
- Students will use a number line to explore and create number patterns.
- Students will use a number line model to explore tenths.
