Learning List recently reviewed

*IM*content for middle school (i.e., grades 6-8).

*IM *content is organized by CCSSM domain (e.g., Geometry), cluster (e.g., “Solve real-world and mathematical problems involving area, surface area, and volume.”), and standard (e.g., “Find the area of right triangles, other triangles, special quadrilaterals, and polygons by…”). For each standard, the program provides a set of printable “learning tasks,” or multi-step problems. Each learning task is accompanied by a “Commentary,” a detailed narrative description of the solution, and a comments section. The Commentary explains the problem, its purpose, and different strategies students may use to solve it. The solutions narrative provides step-by-step guidance in reaching the problem’s solution. The comments section allows users to add their feedback and suggestions.

“Course Blueprints” for grades 6-8 were “Under construction!” at the time of our review (July 2016); Course Blueprints available at the high school level are curriculum modules organized in units with diagnostic pre-tests and summative assessments. Additional instructional materials and professional development modules are available for purchase on the *IM *website.
