Stein - Math 8 Plus - 3.21.17

What We Did Today:

Students went over the answers from Problem 3.1 and completed Problem 3.2 Sliding on a Grid: Coordinate Rules for Translations. Students had to determine patterns between sets of ordered pairs and translated figures. Notes for 3.1 are available at http://norupstein.weebly.com/math-8-plus-blog

 

Focus Question:

What kind of coordinate rule (x,y)→(   ,   ) tells how to "move" any point to its image under a translation?

 

Homework:

None.

Stein - Individuals & Societies 8 - 3.21.17

What We Did Today:

Students completed reading Chapter 12, Section 1 and started reading Chapter 12, Section 2. Students defined the bolded words in the sections using the reading, not the glossary, to build familiarity with context.

 

Homework:

Finish reading Chapter 12, Sections 1 and 2 if not completed in class.

 

Announcements:

There will be an open-book test over Chapter 12 on Tuesday, March 28.

Spanish 2

Students practiced the new Unit 8 vocabulary.

Homework: Pg. 85-86 worksheet

Math 8 - Stone

We worked on investigation 2.2 today. This investigation continued to stress the concept of equivalent expressions. We extended this idea to combining two expressions to get a single expression that would get us a faster result.

For example, we had an expression that calculated profit for an amusement park earned based on the number of visitors. We also had an expression that gave us the number of visitors based on the probability of rain. Our challenge was to find the profit based on the probability of rain. We could work through each expression separately or combine the two.

Stein - Math 8 Plus - 3.20.17

What We Did Today:

Students started Investigation 3. Problem 3.1 - Flipping on a Grid: Coordinate Rules for Reflections. Students took a basic design element on a coordinate grid and found the rule that generalized reflections based on given lines of symmetry. Students also worked on ACE questions 1 – 3, 8, 16, 26.

 

Focus Question:

How can you describe how points "move" under a reflection with coordinate rules in the form (x,y)→(   ,   ) when the reflection line is (1) the x-axis? (2) the y-axis? (3) the line y=x?

 

Homework:

Finish 3.1 A – C if not completed in class.
