Way cool set features 100 happy little penguins that love to be placed atop the 10 projections on each of their 10 ice bars. Ice bars connect horizontally to make a 100 peg grid or end to end to make a number line. Penguins come in 10 brilliant colors and lend themselves perfectly to tool use and all sorts of in-hand manipulative practice, as well as sorting, patterning, and many other math concepts. Very versatile set for individual or group work. Enough materials to split set between 2 therapists or classrooms. Comes with Activity Guide, correlates to NCTM Standards.
