This set is amazing! My students love using these Math Mats to help them practice strategies with manipulatives. This set includes over 800 flashcards, all you need to do is print and you are ready to go. They can be interchanged and used for so many centers. The 6 different Math strategies posters can be used in guided Math lessons or for independent practice in Math centers. Place the math Posters in a page protector and they are ready for the students to write on with a dry erase marker.
