# Simpson Math

## FYI - M-Step Testing begins this week for 8th graders!

Tuesday, April 12th - ELA Adaptive Test (during 2nd & 3rd Hour)

Wednesday, April 13th - ELA Performance Task (during 2nd, 3rd, & 4th Hour)

FYI - 2nd Hour classes will be held during 1st hour period.

8th grade students are starting a new unit this week: TCS - Transformations: Congruence and Similarity. In this unit students will be exploring...

3 Types of Symmetry

• Reflection Symmetry
• Rotation Symmetry
• Translation Symmetry (and Tessellations)

4 Types of Transformations

• Reflections (flips)
• Rotations (turns)
• Translations (slides)
• Dilations (enlargements/reductions)

Transformation Rules - Using rules to transform shapes on a coordinate grid

In the second part of Investigation 2 (INV 2b), 7th grade students will be exploring exponential growth as it relates to the financial world.

• Relating Growth Factors with Growth Rates (% Increases)
• Understanding Interest Rates for loans (credit cards) and investments
• Understanding yield based on compound terms (i.e. monthly, daily, etc.)

Students will wrap up INV 2b with several "Performance Task" activities.

Task 1 - Students will explore how mortgages work

Task 2 - Students will compare several credit card offers

Task 3 - Students will consider 2 offers for purchasing a vehicle (Cash back vs lower interest rate)

## Transformations - Resource Links and Videos

Parents and Students -

These are the same links and videos from the previous newsletter. I wanted to keep these resources accessible since 8th grade is now starting the Unit on Transformations.
