To determine how the toddler should sort the blocks using the GCF (greatest common factor) and the Distributive Property, we first identify the GCF of the numbers of blue and pink blocks.
The toddler has:
- 16 blue blocks
- 20 pink blocks
The GCF of 16 and 20 is 4. This means that each group can have 4 blue blocks and 5 pink blocks (since 16 divided by 4 is 4, and 20 divided by 4 is 5).
Using the distributive property, the toddler can represent the total number of blocks in a way that shows equal groups of blue and pink blocks. Therefore, they could represent it as:
4(4 + 5)
This shows that there are 4 groups, each containing 4 blue blocks and 5 pink blocks.
Thus, the best answer is: 4(4 + 5).
