MS Math – Dec 11 – 15, 2023

6th Grade Math – Mrs. VonFeldt

This week the 6th graders learned about unit rates. A unit rate is a special rate in which we compare to ONE of a thing. The denominator in a unit rate is ALWAYS one. We can turn any rate into a unit rate by dividing the numerator by the denominator. We use unit rates so we can compare rates, such as determining which car is moving faster or which bag of marshmallows cost more per gram. On Wednesday, the 6th grade will take a test on the first half of Chapter 4. It will include ratios, equivalent rates, and unit rates. Here is an example of how we can switch from a rate to a unit rate:

The 7th graders are finishing Module 5 in which we have been learning how to use percentages in real world ways. We have learned how to describe changes as percent increases or decreases. We have learned how to calculate percents of quantities. We have learned to find discounts, tips, tax, simple interest and commission. All of these skills will be useful in our lives. We will be taking a test on this module on Wednesday and celebrating with fun math on Thursday. Students should get all their missing assignments by Wednesday.

For students who need a little extra help or practice on the skills we are working on, they should go into their IXL.COM accounts and work in the areas that have been starred.

8th Grade Math – Mrs. Evans

This week we are using rates, unit rates and proportions to solve real world problems. We will need fluency with proportions to move into some of the new studies, such as similar figures and scaling, that we begin after Christmas break. Here is a video to help students understand solving proportions using cross products:

Algebra – Mrs. VonFeldt

Last week, students finished Chapter 4 on writing linear equations. They now know how to write and evaluate slope-intercept equations, point-slope equations, and standard form equations. Each form is useful, depending on what initial information is given in the problem. Students should be able to take any linear function and put it in another form by rewriting.

This week we will go back to graphing equations with a fun project. Students will graph and color in a series of intersecting lines to create a “stained glass” poster. MERRY CHRISTMAS EVERYONE!
