Reflection: Developing a Conceptual Understanding Intercepts of Polynomial Functions - Section 5: Section 5: Homework


I feel good about where this lesson went and what my students learned.  After looking at the completed assignments, I think there is only one place that some of the students are struggling.  By far the majority could find write the zeros into factors but some had a hard time finding the constant factor.  I think this is a really valuable skill for several reasons.  First, it reinforces the concept that an infinite number of equations share the same solutions/zeros.  Second, it increases their conceptual understanding of the structure of polynomial functions and graphs.   Here is a sample Assignment where all of the zeros were recognized, even if they had a multiplicity of two, but the constant factors were left out.  Assignment 2 appropriately added in the factors.  I think my students require some additional practice so we will continue to look at this skill during the next lesson.
