6th Grade Math – Mrs. VonFeldt and Mrs. Evans
We are working in Chapter 7 in which we are learning a little about algebraic expressions. We are learning how to identify the parts of algebraic expressions, combining like terms and evaluating expressions for a given value. Here is a great video introducing algebra.

In math this week, our 7th graders will be finishing their investigations of angle relationships, triangles and scale drawings. We will start with extending what we have learned about the angles created when two lines intersect to what we get when parallel lines are intersected (transversals). On Tuesday, we will be reviewing the material in this module and then we will test on Wednesday. After that we will begin investigating circles and discover PI!
It is important for students to memorize the different angles so that they can identify them easily and correctly. Here are some of the important angle relationships that they should know:

This week we are finishing up our study (in Chapter 6) of volume of geometric shapes. On Monday and Tuesday, students will present their sculpture projects to the class. We will then move on to algebra. We will extend what we learned in 7th grade and at the start of this year.
Algebra – Mrs. VonFeldt
This week, we finish our study of exponents and exponential growth/decay with a test at the end of the week. Students should be able to simplify exponential expressions, as well as identify and write an equation for an exponential function from a graph or a table. Exponential growth and decay are important functions to understand. They help us evaluate investments, identify population growth or decline, predict bacterial growth, and study many other important scientific phenomenon.
