Why not keep a variety of tools on hand to help teach concepts such as similarities, differences, merging groups and more. These generously sized see through trays fit the bill. They are big enough for group use but can also work for individual use. They work beautifully on our Educational Light Cube, light tables or desks and are deep enought to accomodate a variety of materials. Easy to clean, the set of 3 includes bar, Venn, and graph trays.
Includes: three 10 x 15 x 1″ (25 x 38 x 2 cm) trays and detailed teaching guide.
