Math Learning Center apps are designed for teaching elementary school mathematics lessons. With the exception of the flashcards app, all of the Math Learning Center's free apps are designed to provide you and your students with virtual manipulatives. By the way, the flashcard app is available in English and Spanish.Geoboard is one of the oldest and most popular apps offered by Math Learning Center. It is a good example of how all of the apps are intended to be used. Geoboard is a free app on which students stretch virtual rubber bands over pegboards to create lines and shapes to learn about perimeter, area, and angles.
It is important to note that except for the flashcard app all of the Math Learning Center apps are really just virtual manipulatives designed to be used as a part of lesson plan not as stand-alone practice apps. You will need to provide your students with feedback when they are using these apps.
