# 6th and 8th Grade Math

## Office Hours

Every Tuesday from 3:15-4:00 I have what I refer to as office hours. This is a time when students may come in and begin their homework, work on the script or a reassessment video, or just receive additional help. This week we had several students in for the office hours and many finished all their math homework during that time. If your child wants to attend it is open for all. Below are some expectations for all who come. The purpose of sharing these are to make it clear that this time is for understanding math.

Expectations:

1. Work on math material first.
2. Keep voices down so that everyone can focus on their own material.
3. If a student wants or needs a snack please make sure it is nut free.

## Reassessment

In the same way we do varied assessments for the standards, there will be varied reassessments based on the topics and standards that are being reassessed during the third trimester.

## 6th Grade Math

This week we learned about the volume of three-dimensional figures. Students learned that the formula for the volume of prisms and cylinders is the area of the base times the height. On Tuesday and Wednesday students applied their understanding of surface area and volume to a project. They were given the net of an angry bird (each formed either a rectangular prism or a cube) and had to measure the sides to determine the surface area and volume of their character. On those days students also had the opportunity to ask questions about topics from the chapter and collect extra problems to review for the chapter test. At the end of the class on Wednesday I talked about common mistakes from the second quiz and retaught how to estimate square roots to the nearest whole number and how to calculate the area and circumference of a circle. On Thursday students took the chapter 8 test. Friday we looked at graphing on the coordinate plane. Students came in with knowledge from previous classes and reading/taking notes. We reviewed the terminology and students worked on an activity where they graphed a shape or drawing and made directions using the coordinates of their points to have someone else create the same picture. The 8.1-8.7 quiz was given back in class. We will review it in more detail on Monday, so please make sure that the quizzes are in the folders on Monday.

## 8th Grade Math

This week was all about factoring. Monday the focus was on factoring trinomials with a leading coefficient that is not equal to 1. On Tuesday the focus was on special case trinomials. I talked about how to recognize when a trinomial is a special case and how to efficiently factor it. Wednesday we talked about factoring by grouping. This works for polynomials with 4 terms and can also be used to factor trinomials with a leading coefficient not equal to 1. On Thursday there was review. Friday there was a quiz. Next week students will be paired up (or placed in a group of 3) to complete a project. They will only work on this in class. The chapter 9 test will be on Thursday next week
