HW: Complete the complex number maze, back side 1 - 6 (test prep 4.8) & Person Puzzle - Yuri Gagarin.

Students completed a 3 question warm-up and we went over this in class. We also reviewed the Complex Number Maze from yesterday. We also completed the last couple of questions from our notes on complex numbers. Students had about 15 minutes to complete the Quiz #5.

Students received back their quiz on square root method and completing the square. We went over #2 and #9 from the quiz. Students also played 1 or 2 Kahoot games to review discriminant, completing the square, factoring, and quadratic formula. Then we started our notes on complex numbers. We looked at the definition of i, and addition, subtraction, and multiplication with complex numbers.

Quiz on Quadratic Formula & Discriminant is tomorrow, 10/16. Students completed a 5 question review on completing the square. We checked this in class. We also went over the 3 application problems from WS 4.7. This was collected. Students then completed their short quiz (#4).
HW: Complete the back side of the Discovery Education Check for Understanding (#6) We used the TechBook (Algebra II) section 3.2 to complete the Investigation #4, using the discriminant. Students had time to complete the Check Your Understanding worksheet 1 - 5.
Students also turned in WS 4.7. Students also we reminded to complete the Quiz: Factoring in google classroom. HW: Complete Check Your Understanding worksheet 1 - 5 and be ready for Quiz: Completing the Square and Square Root Methods. Please turn in WS 4.7 if you have not done so. We looked at the type of solutions we get from the quadratic formula based on the value of the discriminant, b^2 -4ac. 4th hour watched the short video below.
https://virtualnerd.com/algebra-2/quadratics/formula-discriminant/discriminant/discriminant-definition We also went over problems 6 & 7 on the Person Puzzle - Grace Hopper. This was collected. HW: Complete both sides of WS 4.7. Working through 5 examples, we completed our notes on using the quadratic formula. Students in 4th hour had about 10 minutes to work on the Person Puzzle - Grace Hopper.
HW: Complete Person Puzzle - Grace Hopper. If you are doing a retake, please complete the additional review that was given. Students started by completing the 6 MC questions on WS 4.6 Test Prep. We checked these together in class. Then we talked about different methods that could be used to solve quadratic equations. Lastly, we started our 4.7 notes which showed how we can use the completing the square method on a standard form quadratic equation (ax^2 + bx + c = 0) and this is how we derive the quadratic formula.
Use the video link below for a quick summary https://www.youtube.com/watch?v=ccQjkBQ44aY HW: Complete WS 4.6 and turn it in tomorrow. As a class we completed the last 2 problems from yesterday's person puzzle. We collected both puzzles (from Monday & Tuesday). Students had about 25 - 30 minutes to work on WS 4.6 which reviewed completing the square method.
HW: Complete WS 4.6 (1 - 15) We finished our 4.6 notes which gave us a technique for solving a quadratic that will always work. Factoring method only works some of the time. We saw that if the solutions were rational numbers (written as a fraction) then the equation could have been solved by factoring. We looked at various problem and found that if we could create a perfect square with the variable side we could use the square root property to solve the equation. We needed to have a 1x^2 and then get the proper c value by taking half of b and then squaring it.

We went over errors and what needs to be done to retake the test. Retakes must be done by 10/18. Then we completed 7 examples of how to solve a quadratic by using the square root method.
