描述

Number Rack facilitates the natural development of children’s number sense. The movable, 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.

FEATURES

• Display 1 to 10 rows of beads, 10 beads per row.

• Hide beads with resizable covers, which allows teachers or learners to model subtraction or difference problems.

• Reverse the colors of rows 6 to 10 to distinguish (or not) groupings of 25 beads.

• Use the drawing tools to annotate work and show understanding.

• Add equations, expressions, and descriptions with the math text and writing tools.

• Share work by saving an image or providing a share code to others. Great for creating the initial setup of an activity, then sharing it with students so they can explore it further.
