رويلكو صواني فرز شفافة 3 قطع

The clear plastic lets kids layer graphs on worksheets—my students finally understood Venn diagrams after using these. Built sturdy enough for daily classroom use.

I grabbed these for my first grader to sort buttons and shells, and the clear plastic makes it easy to check his work without dumping everything out. The three different graph styles mean we can move from simple grouping to a Venn diagram as he gets the hang of it.

The bar and Venn graph trays finally made grouping concepts click for my kid. The clear plastic wipes clean easily and the 10 x 15 size holds a decent pile of buttons or counters.
