MOD 1: Common Core Ratio Porportion Standards & Uiniversal Design for Learning

Big Ideas

The structure and progression of the RP domain leads students to progress from basic ratio understanding to solving real world problems and beyond

Universal Design for Learning (UDL) principles allow all students to more easily access intracacies of ratios and proportional relationships

Ratio tables, tape diagrams, and double number line diagrams aid students in understanding ratio and proportional relationships

Now Let's go to MOD 2: Understanding Ratios and Using Ratio Reasoning to Solve Problems

Big Ideas

Additive and Multiplicative Reasong: multiplicative relationships use ratio reasoning

Instead of relying on basic knowledge of algorithms, use ratio tables, unit rates, tape diagrams, and double number line graphs to represent ratios solve real-world problems.

These new visual models and incorporation of ULD principles, create a foundation to understand ratios that are intertwined the Mathematical Practices

Follow the arrow below. You're 1/2 way done!

MOD 3: Analyzing and Using Proportional Relationships

Gr 6 and Gr 7 Common Core standards complement and build on each other in their progression of RP understanding

Proportional relationships can be deteced and represented with tape diagrams, double number line diagrams, ratio tables, and equations

You've made it! That's a summary of the RP domain and Modules 1-4

MOD 3: Connecting the Ratio and Proportions Standards to Other Domains

Big Ideas

Scale factor can be used to analyze and reconstruct a proportionaldrawing

Proportional reasoning can be extended to connect to algabraic functions

Proportional reasoning can be extended to make predictions and analyze statistics
