January concluded Unit 5: Exponential functions and February welcomes Polynomials and Factoring, Unit 6. We will begin Unit 6 on Tuesday, January 28th. The first three sections cover operations with polynomials, we will add and subtract in 9.1 and learn various multiplication methods with 9.2 and 9.3 including distributive property, table method, and one you may remember; F.O.I.L. The students will come to learn that all these methods are a form of distributing but some ways are easier for students to understand than others. Our first quiz over sections 9.1-9.3 is scheduled for February 5th. The second half of the unit is factoring polynomial expressions. We will look at factoring using greatest common factor as well as the zero product property. Once the students have mastered that concept we will investigate special products such as the square of a binomial and perfect square trinomial patterns. We will complete the unit before the end of the month. Please see Google Classroom for more specific dates as we get into the second half of the unit.
In math lab, the students will begin discovering and practicing different geometric transformations. They will use rotations and reflections to manipulate an image they have drawn and these will be displayed, upon completion, in the hallway. Another notable project that the kids have just completed is “College Trends”. Each student researched data on two college or universities and collected data from 1999-2018, creating a linear regression and exponential regression equation, graphing their data and equation lines on a scatterplot, and answering questions to predict the cost of college when they attend and beyond. This is a great real world application of so many math concepts that we have learned this year and also a valuable life skill. I hope they were able to share their findings with you which may have led to some great, interesting conversations about the value of money.
Please note the second trimester ends on February 28th. I look forward to seeing some of you at parent-teacher conferences on February 6-7th. If you have any questions or concerns, feel free to email me anytime.
