The K"NEX® Education Elementary Math & Geometry set allows students to build, investigate and explore geometry concepts, vocabulary, and structures in a 2-D and 3-D world. The students live in a 3-D world, so it makes sense for them to connect with geometry on a 3-D level. K"NEX® allows them do just that! The teacher"s guide, designed as a resource, provides a glossary of key terms and definitions and includes Vocabulary Card masters to support instruction and understanding. The activities are standards based and designed around best practices in mathematics instruction. They build upon one another as they lead students towards a greater understanding of mathematics and geometric concepts. Set includes 142 K"NEX® parts - enough to build 38 K"NEX® Math models. Support 3-4 students working as a team. Grades 1 - 3. Building instructions and teacher"s guide aligned to national standards and Common Core Mathematics included. Packaged in a strong storage tray with Snap-on lid. Also see K"NEX® Education"s Intermediate Math & Geometry (Grades 4 - 6) and Middle School Math & Geometry (Grades 5 - 9)
