Directions for the students:

1. Make a list of science and mathematical concepts identified in the chapter, such as size, shape, cardinality, one-to-one correspondence, length, and sorting.
2. Gather three sets of the materials from the list above. 
3. Explore the materials to determine which science and mathematical concepts could be taught using these materials.
4. Make a checkmark on the list for each concept that could be taught.
5. After exploring all three sets of materials, post your list on the discussion board and reflect on what you learned through this activity.
