The jumbo attribute set is great for teacher demonstrations and because the pieces are larger it makes it easier for younger children to hold and manipulate. The jumbo set comes in a plastic container with a cover that can be turned to lock all the pieces in place and the cover can be used as a tracing template for the 5 different shapes and sizes. This attribute set contains 60 pieces with 3 different colors red, yellow, blue, 5 different shapes circle, square, triangle, rectangle, and hexagon, and 2 different sizes and thicknesses. Pieces range in size from 1" – 5". Educational products, manipulatives, and kits incorporate applied math and science principles into classroom and homeschoolbased projects. Teachers in preK, elementary, and secondary classrooms use educational kits, products, and manipulatives alongside math, science, literacy, and STEM curriculum to demonstrate concepts and realworld applications through handson activities.
