Students had the first 15 minutes to complete the Desmos activity on end behavior. We checked the first 3 problems on the back of yesterday's summary sheet as well as slides 23 - 26 together. We also worked through the back side of the summary sheet. We generated a graph that met given conditions. Students had 2 to complete on their own.

Students worked through the Desmos activity: end behavior which lead students through various polynomial graphs and conclusions about the end behavior of those graphs and corresponding equations. Together we shared students' rules for categorizing the graphs.
Then on slides 16 & 22 we summarized our conclusions as a large group. We came up with this generalization: For polynomials with even degrees, if a> 0 then the end behavior is up, up. For polynomials with even degrees, if a< 0 then the end behavior is down, down. For polynomials with ODD degrees, if a> 0 then the end behavior is down, up. For polynomials with ODD degrees, if a< 0 then the end behavior is up, down.

Retake of Test 3 (factoring methods) must be done by March 19th. HW: Complete the Desmos activity: end behavior. Students completed Test 3 (DMA 21) on factoring methods. 3rd hour will have up to 15 minutes to complete it due to the fire drill today.
Students completed the week 2 SAT math question & filled out the form in the Resources of their google classroom. Then students worked on completing their DE Quiz on Factoring (go to discoveryeducation.com & log in with your school google account). This should be completed before your test tomorrow.
Students were also able to check their work on the Study Guide with answer key posted in the Stream of their google classroom. HW: Complete the DE Quiz on Factoring & any missing work. Test 3 is tomorrow, March 5th. During the first 20 - 25 minutes, students worked with a partner on 6 factoring questions. Then students used the rest of class to complete their review, and start their DE Quiz Factoring Polynomials.
HW: Complete your study guide & any missing work. Test #3 is Thursday March 5th. Students were given the whole class period to work on classifying which factoring method to use and then practiced GCF, trinomials, and difference of squares.
We also went over questions from Thursday's worksheet: Factoring Polynomials over the Real Numbers. HW: Complete the first page of the review. Test #3 is this week, on Thursday, 3/5. We played 2 Kahoot games that reviewed 5 factoring methods: sum & difference of cubes, GCF, trinomials (both with a = 1 and a not = 1) and difference of squares. Then students had time to complete the rest of the WS Factoring Polynomials over the Real Numbers (1 - 16).
HW: Complete WS Factoring Polynomials over the Real Numbers (1 - 16). Students were given an SAT warm-up question to complete and filled out the corresponding google form.
Students completed 5 - 7 on the factors and zeros worksheet. Then we completed a couple problems from the front side (Kuta Analyzing & Solving Polynomial Equations). We worked out x^3 - 1 = 0 by first factoring it with the difference of cubes formula. Then we found the zeros by using the quadratic formula on the remaining trinomial. Lastly, we reviewed factoring trinomials where a is not 1 and not a GCF. This used the box method and we completed about 6 problems together. HW: Complete 1 - 8 on the front side and finish 1 - 10 on the back of WS Factoring Polynomials Over Real Numbers. Students named the zeros given a function in factored form. We did 4 of these in class and checked them. Students were reminded that the square root of -1 is i. We went over questions from WS 5-3 and completed #14 together. We also started the sum/difference of cubes pun worksheet, completing the first couple of rows together.
HW: Complete the front side of the worksheet Kuta Analyzing & Solving Polynomial Equations & complete the sum/differnce of cubes pun worksheet. Students used desmos.com to graph y = x^4 - x^2 - 12. Then we looked at a factored form and saw that the graphs were identical. We noticed that without all the factors in place, the graphs will not be the same. Then we complete our notes on factoring the sum & difference of cubes. We did 5 examples together.
