Gr 6_NS_FractionsDivision_Problem_Critique

This problem was used by students after working visually and conceptually to explain division with fractions. They use this problem as a transition to dividing fractions using the mulitplicative inverse. Students benefitted from constructing a diagram that showed the fence sections. Constructing the diagram on graph paper, using 20 squares for the length helped students divide equally and find the fraction they needed. Explaining the connections between the diagram and the equation are very important for constructing the argument.

Gr 3_OA_DivisionSingleDigit_WordProblem_Construct

This task is used with third grade students. The task is an application of single digit division, but encourages students to draw a picture in order to construct an argument. The application asks students to distribute cookies to 5 people, given 15 cookies. Students must construct an argument by stating a claim and providing evidence. Students are then encouraged to engage in a pair-share and understand a partner’s thinking.
