Today we went over 10 review problems in class where students used white boards to do their work. 3rd hour also went over a couple homework questions from book 4.8.

Quiz over 4.8 is tomorrow. We completed our note sheet from yesterday where we used the for operations of add, subtract, multiply and divide with the complex numbers. Then we solved 2 quadratics equations that had complex numbers as solutions. We showed how to store the value in the graphing calculator to check our answer.
Homework: Page 253 - 254 20 - 34 even, 35, 38 - 43, 48, 50, 52, 68, 73 - 76, 78, 80 We did a review of adding, subtracting and multiplying complex numbers, as well as determining the absolute value of a complex number. We completed 2 examples on dividing complex numbers (used the conjugate of the denominator to multiply by a fancy #1). Then we looked at factoring the sum of squares using complex numbers. x^2 + a^2 = (x + ai) (x - ai). We completed 15 - 20 on WS 4.8.

Bring your book to class tomorrow. Students completed the WS 4.8 vocabulary support in class. We also went through examples of how to add, subtract and multiply complex numbers. Students were given the last 15 minutes to complete their test from Friday.
HW: Complete 1 - 11 on WS 4.8. Bring your book tomorrow to class. Students worked on their test 4.1 - 4.7. Study guides were collected.
Enjoy your weekend! We went over the study guide in class. We also completed 2 more level 4 type problems.
Test on 4.1 - 4.7 is tomorrow. Any missing work from chapter 4 is due then. Know your study guide. 10 Review problems are on www.tenmarks.com We went over any questions from book assignment 4.7. This was collected. Students completed an exit slip (4 questions) on 4.7. Students also received a study guide for the test on 4.1 - 4.7.
HW: Study Guide should be completed by tomorrow. Test 4.1 - 4.7 is Thursday. Students were given 6 equations and asked to solve them using the most efficient methods. We went over the factoring method, completing the square and quadratic formula. We also showed how to use the memory on the calculator so we could check our solutions. Students also received back their quizzes from last Friday.
Then we quickly explained how the discriminant can tell us how many and what type of solutions we will get from a quadratic equation. HW: Complete book assignment 4.7 if not already done. Test will be this Thursday, October 22nd over 4.1 - 4.7. We completed our class notes on using the quadratic formula (section 4.7). Then students were able to work with a partner and had 25 minutes to complete the quiz 4.6 (square root method and completing the square).
