Reflection: Connection to Prior Knowledge Area "Quest" - Section 1: Individual Assessment

 

I included problem #8 on the Area Quest to assess my students’ strategies for decomposing 2-dimensional figures, a skill we have worked on throughout the entire unit.  This problem gives students the opportunity to look for and make use of structure as they consider how to find the area of the shaded region of the octagon-square figure.  Without prompting students, the problem implicitly requires them to draw line segments (whether physically or in their minds) to make sense of how much of the figure they must consider.
