Number Rack, by The Math Learning Center

186,155

The Number Rack facilitates the natural development of children’s number sense. Rows of moveable, colored beads encourage learners to think in groups of fives and tens, helping them to explore and discover a variety of addition and subtraction strategies.
This virtual version of the manipulative is an open-ended educational tool, ideal for elementary classrooms and other learning environments.
Visit The Math Learning Center for more information about using the Number Rack, including a free activity guide: www.mathlearningcenter.org/apps.
