# 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 5_OA_EstimationDivision_Problem_Critique_TedAndJP

Ted and JP is a task designed for fifth graders in working on division and estimation. A problem is presented in which students must estimate a quotient, and students must critique two estimations and decide which is better. This requires students to critically think about how to make a good estimation. Students must state which estimation is better and explain the answer.

# Gr 5_OA_DivisionRemainders_Problem_Critique_JakesIdea

Jake’s Idea is a problem for fifth graders on division with remainders. Students are given a statement that a four-digit number will have a remainder when being divided by 4 and must take a stance. Through argumentation language, students must critique the statement and give evidence to support their claim.

# Gr 5_NF_FractionsMultiplicationDivision_Problem_Construct_MakingHotCocoa

Making Hot Cocoa is a task on fraction multiplication and division for a fifth-grade classroom. Students are given a certain amount of cocoa powder and the fraction amount needed for each cup. Through a series of questions containing argumentative language, students are asked to construct a response to how many cups of cocoa they can make. Students are to construct a solution through a variety of methods, including pictures, mental thought, multiplication, and division. Sample solutions and commentary are provided.
