sophia park on 04 Mar 15This website contains a wide variety of virtual manipulative that can be maneuvered by all learners at all stages. Both students and teachers can use this to demonstrate understanding as well as modeling a strategy. All viewers are able to see concrete place values as well as the composition and decomposition of hundred and ten blocks. It is a great tool for the visual learner and those who are still in the concrete stage in addition/subtraction.
