HW: Complete the desmos activity, WS 4.4 Test Prep 1 - 6, and the first 2 problems on Graphing Quadratics in Intercept Form WS #2.

Students were given the first 15 - 20 minutes of class to work on the desmos activity: roots of quadratic functions. If this was completed students did WS 4.4 Test Prep 1 - 6. We also went over a couple of the factoring by grouping problems & collected the circuit training. We also discussed the quiz results & questions.

Students reviewed completely factoring trinomials by working out problems on the board. Students had feedback from their peers as well as the teacher. Students worked on completing the Circuit Training - factoring by grouping. Students also completed their quiz.
HW: Complete & turn in the Circuit Training - factoring by grouping & do Desmos: Roots of Quadratic Functions. The we saw how the grouping method (given 4 terms) is just a variation of the box method. If students do not wish to use the box method, we used the idea of grouping the first 2 terms together & then the last 2 together and taking out the GCF of each group. This should give a common group to factor out.

Students completed WS 4.4 in class as we did 19 - 22 & 35 - 39 together. We also went over questions from 23 - 34. 5th hour had time to go over the graphing in intercept form exit slip. Then students had about 20 minutes for their quiz #2. Most students did not finish the quiz and will get 5 - 10 minutes to complete the quiz on Monday.
HW: Complete Circuit Training - factoring when a is not 1, turn in any missing work! We started by playing Kahoot to review using standard form of a quadratic. Then we collected the circuit training factoring worksheet and went over questions on WS 4-4 1 - 18. Students have their notes in google classroom, where we did 3 examples using the box method. Students had 2 more problems for additional practice.

You may start working on the second Circuit Training Worksheet (due on Monday). We went over factoring methods of GCF, difference of squares, perfect square, simple trinomials where a = 1. Students have their notes in google classroom. We also completed the first 5 - 6 problems on the Circuit Training Worksheet.

We checked through homework on graphs 1 - 6 and the first 2 pages of the packet Graphing in Factored Form. We looked at how we could use intercept form to write the equation of a parabola given its x-intercepts and a point on the graph. We used the three given points to determine the value of "a". We did #7 & #12 together from Monday's worksheet.

We looked at how we could use each of the 3 methods to answer this question. We spent more time on intercept (or factored) form of a quadratic. Students received their notes on google classroom and we 3 problems together. We were reminded that a y-intercept can be found by letting x = 0.

Given 2 x-intercepts, we looked at how we could write the equation for a parabola though them using vertex form as well as standard form. We also saw that x-intercepts were related to the "b" and "c" values when we used x^2. b = opposite sum of the x-intercepts and c = product of the x-intercepts. We used desmos to check our work. We also started to introduce a third way we could write the equation of a parabola, intercept form (also called factored form).
Intercept form of a parabola is y = a(x - x-intercept)(x - the other x-intercept). Use the video link below for review or practice: https://www.youtube.com/watch?v=BF5VxWUg92o HW: Complete the 2 desmos activities from this week: Quadratic Transformations & Parabolas Matching Factored Form. Students completed the 6 multiple choice questions on WS 4.2 Test Prep. We went over this in class. We also went over WS 4.2 and collected it. Then students are to complete the first 4 slides of Desmos: Parabola Matching Factored Form. We discussed slide #2 together and found that we could use both vertex form and standard form to create an equation for the parabola through the 2 given x-intercepts.
