Reflection: Checks for Understanding Distributive Property - Section 4: Group Practice


For this group work I didn't have set problems.  I used the lesson's discussion to assess students' understanding of the concept.  For the board work, I chose the 6 students who I knew would benefit the most from my attention.  Depending on the student, I gave them a problem that would suit their needs.

Two of these students really struggle with word problems, so I gave them a problem they had to break down and use the relevant information to apply to the distributive property.

Example of a problem:  Emily has 50 games at home.  Yesterday Emily bought 6 games at the store.  Games cost $21 each.  She bought 7 more today.  How much money did she spend on games?

I realized that as students were at the board working out problems, that I needed additional problems for the class to work on.  With these, I also included "Challenge" problems that students are always eager to try.

Example of challenge problem:  Write the distributive property in reverse and explain or show whit it would way it would be easier to calculate the answer.       19 x 354 + 19 x 646
