On Friday, we took time to look at two "polynomial puzzlers" from various sources. Students were challenged to solve each of the attached. As an added bonus, we took a brief detour and discussed synthetic division of polynomials by binomials.

To support our understanding of multiplying polynomials, and to get some enrichment material, we looked at the binomial theorem and studied Pascal's Triangle, looking at applications to algebra and combinatorics.
This lesson explored multiplying polynomials using both distribution and visual (array) models.
Another video lesson (due to illness) had students adding and subtracting polynomials. We did this both vertically and horizontally.
This video lesson asked students to classify polynomials by degree and number of terms. Students were asked to simplify expressions first and then classify.
This first message for Algebra 1 content focused on reviewing and extending our understanding of some basic properties of mathematics.
Here is the Study Guide and Answer Key for Module 7 material. Please note that while there might be some differences between the references to lessons and Khan in the SG Key, the answers are indeed for the questions you received. Let me know if you have any questions.
Our final lesson of Grade 8 math looked at applications of the Pythagorean Theorem--some involving geometry, other involving cutting corners.
Another application of the Pythagorean Theorem is the distance formula used to determine the length of lines on a coordinate plane. In this lesson, we practiced finding diagonal lengths on a coordinate plane.
We used our understanding of the Pythagorean Theorem in this lesson to prove that triangles either were or were not right triangles.
