Reflection: Quizzes Quiz 1 : Assessing addition and subtraction of like denominators - Section 2: Quiz 1: Administering the quiz


The quiz results were really interesting. We had spent little time drawing models in simple addition and subtraction problems because the majority of students showed me they could do that on a pretest. Somehow, in this quiz several students reverted to using two bars that would show comparison as if they were comparing equivalent fractions. Hmmm? It is interesting to see how that happens and I know when I talk about it with them they will say "Oh yah!" But for me, it says that the concept is not strong enough. In this short video clip, I show two examples and quickly talk about what I am seeing.
