This light table resource offers a fun way to practice number recognition. Students can roll translucent dice (or dice in dice) on the light table and cover the number.
Although this activity is intended to be printed on transparency film, it can also be printed on paper and used as a regular table activity.
Suggested manipulatives: translucent shamrock shapes, translucent gems, mini erasers
* I highly recommend laminating your transparencies to protect the ink and extend their life-span.
