Chapter Eleven: Transformations

Hello parents and guardians,

We are currently in chapter 11 of the 16 chapters in the accelerated program. Chapter 11 is on transformations of shapes and is a visual and hands-on chapter. It requires students to visualize and perform translations, reflections, rotations, and dilations on graph paper. We will also discuss the applications of transformations in computer science. The chapter test is scheduled for Thursday, March 24 (there is no school that Friday).

Right in the middle of this chapter, we will take two periods to complete a practice PARCC math test. Students will take this practice test in paper/pencil form first. We will then practice how to input answers online at a later time. The accelerated class will take the practice test during their back-to-back math blocks this Friday, March 18. Scores will be calculated but will not be included in students' math grades. The real PARCC math test (a timed computer test) has been scheduled for May 17, 18, and 19 for our team. The ELA PARCC is scheduled two weeks earlier on May 3, 4, and 5.

What you can do at home: The rotation problems are especially difficult for many students. I encourage you to try one yourself! Where will the blue triangle fall if its rotated 90 degrees counter-clockwise around the middle of the graph? Picture it in your head or sketch it down on a piece of paper. Then, scroll all the way down for the answer.

Here is the answer to your rotation problem. When asked, "How many of you have trouble visualizing these rotations?" Almost all students raised their hands. Only a few said they found it "easy." Certainly should be an area of focus when studying for the chapter test.

Thank you for your support at home,
Ms. Vila
