1. Comprehension & Application

SMP.6: Attend to precision.

 

In part b, the student writes an equal addend equation with an incorrect sum, indicating a lack of precision in calculating. The student wrote the incorrect total in both the equation and the verbal expression, which demonstrates that the student knows the total should be the same for both representations. It is unclear how the student came up with a total of 12, but the student does demonstrate an understanding of the idea of repeated addition in this and the other parts.
