Today in math we took notes on when a parabola has no roots. In the quadratic formula, if you solve the b squared minus four-a-c part and the answer is negative before you square root it, this means there are no roots for the parabola. The vertex is above the y axis. This number, under the square root is called the discriminant. If the discriminant is 0, the vertex is on the x axis. Some say that could mean there is one root but others say it is two roots in the same place. If the discriminant is positive, yay! there are two roots. The vertex is below the x axis. This makes sense for circumstances like rocket launches. Due today are the completing the square sheet, quadratic formula sheet, and the vertex form sheet. These are on google classroom, with the exception of the vertex form sheet, I think. Have a happy Halloween! Below is a Jack-o-lantern. (:

Today in math we derived the quadratic formula and learned how to use it. Here is a photo of Andrew's steps for using the formula. The quadratic formula problem set is due tomorrow. The sheet is on Google Classroom. Feel free to ask any questions in the comments below! 😀
Sorry for the delayed posts last week. Weebly has been not working.
Today in math we received our tests back. You can correct questions and receive 3/4 of the score back. We also did an activity about completing the square. We drew boxes which represented different values of x and one. And the number of boxes corresponded with the equation produced from multiplying two x values.
Here is my paper for reference.

Today in math we took notes on the different forms of a quadratic equation and how to convert from expanded form to vertex form. Then we completed a kahoot and had study time. All sheets are in the classroom. The test is this Friday.
Today we continued to review for the test. We reviewed the essentials of quadratics, how to read the equations, how to write them, and how to graph parabolas. We also continued to work on the study guide. All handouts given in class are on the Google Classroom. The test is this Friday.
We got new seats today in math, and we worked on a study guide and a problem set to review for the quiz/test. All of these sheets are on the google classroom, I believe the code is ilmim5, if you are not in the class. The quiz/test is this Friday, it will cover all quadratics we have learned. Tomorrow, we will be working on another problem sheet to prepare. The way Andrew will score the quiz/test is as followed, if you wish to re-do any missed problems you can provide a corrected written explanation and receive 3/4 of the points you could have earned back. You will not be able to retake the whole quiz/test.
We had no math today due to SLCs. We will be cooking with our ovens tomorrow. Here is a math joke, what do baby parabolas drink? Quadratic Formula!
Today in math we continued to work on our solar ovens. They were due today, we will cook with them on Thursday. Be sure to fill out your SLC paper in math. Our test is next Friday, don't forget to pick up a study guide from Andrew. We will be reviewing all of next week!
In math we worked on SLC forms. The forms had reflective questions for everyone to fill out. Be sure to have a parent sign the slip. I believe the parabolic solar ovens will be tested Wednesday, so plan accordingly. There is going to be a math test soon, be sure to grab a study guide from Andrew.
Today in math we worked on our parabolic solar ovens. The "skeleton" without mylar was expected to be done today. We will be adding mylar tomorrow, and our goal is to test the ovens on Friday. There is going to be a quadratics test next Friday, so be sure to grab a study guide from Andrew!
