Waters’ Mission
Waters' mission is to prepare our students for lifelong success
by providing an inclusive and caring learning environment,
that emphasizes cultural, artistic and ecological connectedness.
Acceleration at Waters
Ensure all students grow over school year
Prepare Middle School students for success in High School
Depth of Knowledge
Level 1 - Recall, Knowing Stuff, Labeling
Level 2 - Execute Procedures, Summarize, Identify Patterns
Level 3 - Use Evidence, Argue, Synthesize Sources
Level 4 - Create, Design
Common Core Standard (3rd Grade)
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations.
Depth of Knowledge
Level 1 - Recall that multiplication and division are inverse operations.
Level 2 - Solve a Multiple Choice Question
Level 3 - Prove with evidence that 3*5 =15 can be used to solve 15/3
Level 4 - Create a board game using multiplication and division within 100.

Three “Legs” of Math Rigor
Acceleration Focus:
Conceptual Understanding
&
Application
(already well- developed fluency)
Example: Grade 7
Proof of Vertical Angles Theorem:
If students understand the why, they’ll figure out the what
Example: Grade 8 (Algebra)
Maria had $10,000 to invest. She decided to invest her money in bonds and mutual funds.
She invested a portion of the money in bonds (b) paying 4% interest per year and the remainder in a stock mutual fund (m) paying 6% per year.
After one year the total income she had earned from both investments was $550. How much had she invested in each type of investment?
Example: Grade 8 (Algebra)
Do you think Maria has more of her money in bonds or mutual funds?
How do you know?
Is there one equation you could write to figure out how much she invested in each type of investment?
Could you write two equations to figure it out? If so, how could you figure out the values for b and m with your two equations?
Example: Grade 8 (Algebra)
One Strategy: Create Two Equations and Solve them Together
b + m = 10,000
.04b + .06m = 550
Use elimination to solve the system of equations (multiply equation 2 by 25, then subtract to isolate m):
m = $7,500
b = $2,500
