This interactive PowerPoint presentation involves learning how to add fractions with unlike denominators. Modeling is used to generate rules. Students will be engaged with questions that allow them to investigate, ponder, calculate, and recall. The concept is based on 5th grade Common Core math standards MCC5.NF.1 & MCC5.NF.2 under the domain of Number & Operations - Fractions. Addition with common denominators if reviewed first before investigating how to add with unlike denominators. There is an adequate amount of animation to keep student interest as well. I estimate anywhere from 15-25 minutes of time to use the presentation dependent upon the amount of student involvement. You can also use this presentation for an individual student who may have missed the lesson or needs re-teaching of the concept.
