Math Week 11-7-16

7th: This week we continue to use proportional thinking and reasoning by applying it to similar figures. We will define the vocabulary of similar figures and then use the vocabulary and similar relationships to solve tasks. We will end this week indirectly measuring the height of the big cottonwood tree in Ray's east field!

8th: We will continue with another building block for students to learn about the language of algebra and how we use that language to understand the world through relationships and patterns. We specifically focus on the distributive property. Over the next few months we will continue to learn how these blocks and others like them come together as a mathematics literacy that helps us make meaning of our world.

7th:(Due 11-3-16) 

Find something that you can quantify in your daily life. Measure or count your chosen thing on Monday or Tuesday. Measure or count the chosen thing again on Wednesday. Determine the percent change between the first day you measure and the second day you measure. Examples of things to count:

• How many people at your lunch table brought their lunch?
• How many cars are parked on your block when you get home from school?
• How many political commercials did you see on TV?
• How cold is it when you leave for school?
• Literally, anything that can be counted or measured?

8th: (Due 11-3-16) 

Create a new foldable (definition and example please) or the math vocabulary listed below:

1. Expression

2. Equation

3. Coefficient

4. Term

5. Like terms

Math Week 10-31-16

7th grade: We continue to think about percents as a special proportional relationship. We have recently spent time talking about how people really like using percent to determine how much money will be saved or earned or charged. This week we spend looking at the idea of percent change. When people talk about increases and decreases we like to talk about them in terms of percent of increase or decrease-- in effect, telling how much a given measurable situation has proportionally changed.

8th grade: We spent last week on the concept of slope as rate of change. This is a building block for students to learn about the language of algebra and how we use that language to understand the world through relationships and patterns. This week we begin to study the symbolic language of expressions and equations as way to describe those relationships and patterns. We specifically focus on the concept of "like terms". Over the next few months we will continue to learn how these blocks and others like them come together as a mathematics literacy that helps us make meaning of our world.
