Homework- Direct and Inverse Variation

We need to practice more on direct and inverse variation so our homework today was a worksheet that I handed out. Some of the answers are shown to help you with any questions you might have.

P.S. We might (will) have a small quiz over this on Thursday!

Constructions!!!

We will be working with constructions all week. You will turn in a Construction book at the end of the week. The rubric that you will be graded on is attached. I have also attached some videos to demonstrate the constructions being made to help you if you are working on the project at home. 

 

Here is the only powerpoint that we will be using for notes. The rest will be taken in class as we construct on Tuesday. Notes

Here are the standards we are covering: 

M7G1. Students will construct plane figures that meet given conditions. 

a. Perform basic constructions using both compass and straight edge, and appropriate technology. Constructions should include copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line. 

b. Recognize that many constructions are based on the creation of congruent triangles.

Test information!!!

We will have two quizzes on Friday 11/11/11!
The quizzes are on:

• Monthly Skills Quiz- Fractions, decimals, percents, and integers.
• Linear Functions and Direct and Inverse Variation

STUDY!!!

Standards Link!

Here is a link to the standards which you will be tested on in the spring during the CRCT! Standards

Student work!

These are pictures of just some of the projects that we had during 1st quarter that exceeded expectations!
