Students received their Friday quizzes back and we went over the application problem (#6) together. Students had the rest of class to work on the study guide for test #3.

Students went over questions from the Quadratic Equations Worksheet (1 - 19 MC) and this was collected. We also went over #13 & #15 on WS 4.7 as well as the front side of the Quadratic Applications Worksheet.
Students had the last 15 - 20 minutes to complete Quiz #7. HW: Complete Quadratic Applications Worksheet and complete through #7 of the Fastball Lab. Test #3 will be next Friday, 10/18. Students had the first 7 minutes to solve equations that used factoring and the square root method. This was part of tonight's homework. We discussed when the discriminant was negative, there was no real solutions (no x-intercepts). With the use of complex numbers, we are able to get complex numbers for our solutions. We showed how to check our answers by using the store feature on the TI-Nspire. We completed 7 equations together in our notes.

Quiz #7 is tomorrow over the quadratic formula and discriminant. Our test will be next Friday, 10/18. Students completed a 3 question warm-up on discriminant and quadratic formula. Then we went over any questions from the front side of WS 4-7. Then we collected data for our How Fast is Your Fastball Lab. This is a summative grade and is due October 22nd. Students worked together to measure their initial heights. We went outside where student threw a baseball upward and another student measured its hang time. Students recorded their best (highest) hand time.

Students worked on completing the discriminant & quadratic formula packet from yesterday. Most of this was checked in class. We also showed how to get decimal estimates of our answers by using the TI-Nspire calculators. Students had 20 - 25 minutes to work on WS 4-7.
We also showed how the axis of symmetry (or the x-value of the vertex) of a standard form quadratic is x = -b/(2a). This comes from the quadratic formula as being in the middle of the x-intercepts. HW: Complete the front side of WS 4-7. You'll have 10 minutes to complete the back side tomorrow in class. Tomorrow wear your favorite baseball gear. Students watched a short video about fixed versus growth mindset. We discussed how a growth mindset is useful in putting forth effort into our learning, whether it is current material or retaking test #2 (due by 10/17).
https://www.youtube.com/watch?v=Xv2ar6AKvGc Students used about 30 minutes to work on the Desmos activity: discriminant and the quadratic formula. Students were able to see what happened with the graph as they adjusted the standard form values of a, b, and c. Students were encouraged to make connections and conjectures about the relationship between the discriminant and the number of roots on the graph. During the last 10 minutes, we worked on a couple problems together from the Discriminant and Quadratic Formula Packet.

Students completed a 5 question entrance slip that we went over in class. This reviewed some concepts from test #2. Then we worked on 3 -4 problems on the back side of our quadratic formula notes. Students turned in any missing work and had 15 minutes to complete Quiz #6 on completing the square.

Enjoy the weekend! Students started by completing the 7 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 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 any missing work. Quiz #6 is tomorrow on completing the square. Students were given the first 5 minutes of class to work on the simplifying radical expressions (1 - 10). We checked 1 - 4 together and students had more time to complete that side. Once completed, they used remaining time to work on completing the square method with the puzzle: What is the name of the Picture?
Students had the whole class period to work on both sides of the worksheet. HW: Complete WS: What is the name of the Picture (both sides) & complete WS 4.6 front side only. We started with a review of simplifying radicals (something done in geometry with Pythagorean theorem). We did 5 examples together and students completed 12 problems on their own. We checked these in class.
Then we completed #7 and #8 together from yesterday's person puzzle. This was collected.

HW: Complete the front side of WS 4-6 (1 - 15). |
