This is an animated PowerPoint presentation on using number lines to find sums, differences, products and quotients and adding equivalent fractions. I have included tangible real-life examples to illustrate concepts. Proper terminology, word problems, hands on experiments and use of everyday items are used to illustrate concepts. Interactive questions are designed to engage active participation. These slides also teach how to draw and properly label number lines. One slide can teach multiple points however the animation allows the lecturer to present one idea clearly at a time walking the students through the main concepts. The slides are grouped for each subject area (addition, subtraction, etc) to allow the presentation to be given in multiple times. Hope your kids will enjoy this presentation as much as my 3rd grader and I enjoyed creating it! Let me know what you need and I will gladly try to create it.TOU: Purchase/download of this product allows the purchaser to make copies for personal classroom use only.
