Reflection: Complex Tasks Area & The Distributive Property - Section 3: Working Together


My students needed constant support and help throughout this lesson. In reteaching this lesson, I would make sure to use smaller pieces of paper and larger units.  This task was too complex for my students at this time in the year, and it is something that will need to be revised and retaught over several days. 

Only two of my students were able to explain this task, and the next time I would create marks on the smaller pieces for the fold lines for the students. I would also have the students glue the strips of paper onto the larger piece.  Additionally, I think it may be helpful to students to have different colors of paper for this task.

 Another option would be to focus more on this concept using grid paper. 

The distributive property is a complex and new idea for third grade students.  Taking time to introduce this slowly is essential for their success.  Some of students clearly were not ready to take on this task, and I should have worked on this with students in small groups.
