Engage younger students with jumbo wooden Cuisenaire rods. The introduction set comes with 56 jumbo rods. These easy-to-handle, large wood pieces are perfectly sized for younger kids and range in size from a 2cm cube to a 2cmx2cmx20cm rod. The rods come in 10 different sizes and each size is represented by a different color: white, red, green, purple, yellow, black, blue, brown, orange, and dark green. Set also includes an activity poster. Educational products, manipulatives, and kits incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use educational kits, products, and manipulatives alongside math, science, literacy, and STEM curriculum to demonstrate concepts and real-world applications through hands-on activities.
