In May 2015, seventeen ITEST projects presented videos in the 2015 National Science Foundation Teaching and Learning Video Showcase. Organized by TERC, the showcase contained 112 videos produced by NSF-funded projects associated with one of these resource centers: ARC, CADRE, CAISE, CIRCL, CS10K, MSPNet, and STELAR.
This video describes the SolveMe Mobiles app, which is designed to support algebraic reasoning in a fun and interactive format. These colorful puzzles help algebra and pre-algebra students as well as puzzle-lovers of all ages establish and strengthen the logic of solving equations for unknown values. Play SolveMe Mobiles at http://solveme.edc.org or learn more about the project.
How algebraic reasoning can be fostered within the important big idea of equivalence is demonstrated using hanging mobiles. A concrete-representational-abstract approach is used, without any formal algebraic symbolism, to elicit algebraic reasoning and higher-order thinking.
