This is a great method for reviewing fractions with your students. In addition, this technique will also be great for students that are visual learners. The only disadvantage would be that the pieces may get misplaced or lost; therefore, new ones would have to be made to replace them. However, I do feel like this method will be useful in several ways.
This counting method for math will not bore the students. It will make learning to count be an enjoyable experience. However, this technique is probably best for a hands on learner and not so much a visual learner.
This is a cute idea from Mrs. Goodroe, the wonderful kindergarten teacher across the hall from me who also came up with the other ladybug math idea. It is such a blessing to work with such talented teachers!!
