1. Understanding

In this question, the student gives a different total for the sum of the repeated addition and the total number of spoons in the group. This indicates that the student might not understand that the sum of the repeated addition equation needs to represent the total number of objects. Although the student made a mistake in finding the sum of 8 + 12, if the student understood the meaning of the repeated addition equation, the student may have caught the computation error.
