The National Library of Virtual Manipulatives (NLVM) is a collection of virtual manipulatives for teachers. This is a fantastic to engage students in math and contains collections of manipulatives for each math strand with categories for Pre K-2, 3-5, 6-8, 9-12. This NLVM, if you haven't used it before, is a resource from which teachers can freely collect resources to enrich our math programs. You can find manipulatives for whatever you are teaching and incorporate these into lessons, use it as an exit card, or use it to differentiate for IEP students.
If you have used this before, check it out! It's a great resource!
