Here are some more pictures of my Math materials area.
These are the shelves my husband built. I have 5-6 baskets of the most frequently used manipulatives since I have 5 tables the children sit at. This makes it very easy to pass out materials and I don't have to get them ready ahead of time. The empty shelf holds the baskets of pattern blocks that we were using when I took these pictures. After trying many ways of organizing the items, I have found that this works best for me. I do have a few other materials put away that we don't use as frequently such as Base 10 blocks.
We start using math materials the very first day of school and go over the rules and procedures for getting them out, using them and putting them away. The children are very good at taking care of the materials. They love using them and this set-up has helped me avoid many headaches concerning the mess that materials can make.
