Description
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 that use iPod Touches, iPhones, or iPads.
FEATURES
• Display 1 to 5 rows of beads, 10 beads per row. On the iPad, display up to 10 rows.
• Hide beads with the resizable shade, which allows teachers or learners to model subtraction or difference problems.
iPad only:
• 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
• Write equations and expressions with the text tool.
