Jumps on a Number Line

cults3d

Model expressions and equations on a number line with positive and negative jumps. Print out positive and negative jumps, then place them standing up on the number line to build expressions. Create two expressions that start at zero and end in the same location to form an equation. This is a powerful hands-on modeling tool to help students bridge the gap between real-world situations and symbolic representations. Teachers: Two worksheets (pdf files) are included for students to use along with this manipulative. The worksheets provide examples of how to utilize the tool effectively. The following Common Core standards are associated with this manipulative: K.OA.2, 1.OA.1 2.MD.6, 6.NS.5 and 6.NS.6 6.EE.2 and 6.EE.6 SketchUp source files (in a zip archive) are included for further use.
