Jumps on a Number Line

thingiverse

Create expressions and equations using positive and negative jumps on a number line. Print out jumps in different colors, such as green for positives and red for negatives, to distinguish them easily. Combine these jumps to form an expression that starts at zero and ends at a desired point, then repeat the process with another expression to create an equation. This hands-on tool helps students understand the connection between modeling situations and symbolic representations. The Common Core standards associated with this manipulative include K.OA.2, 1.OA.1, K.OA.2, 2.MD.6, 6.NS.5, 6.NS.6, and 6.EE.2. Teachers can use provided worksheets as examples for students to follow. SketchUp source files are also included for easy access to individual jumps.
