## Reflection: Connection to Prior Knowledge The Number Ten - Section 3: Number of the Day: 10

I have several students who have already mastered their ten facts and know how to find all of the combinations of ten.  So, I gave them a sheet that asked them to make 20.  This way I could see if they used their knowledge of 10 to come up with combinations of 20 (strategically).  There is an example of a student who demonstrated this understanding in this section's resource.
