To use as a traditional Montessori finger chart, print two copies of the second page and cut the number tiles from the chart. The child will place the the proper addition sum answer on the blank finger chart to fill it in. For best results, print on card stock and laminate. Alternatively, you may have the child fill in the blank number chart himself. For reuse, laminate the chart and use with a dry erase marker. For best results when laminating, print on card stock.
