Through This Assessment Opportunity…
Students will demonstrate the concepts and skills that they have developed through these contexts and learning experiences related to ratios, percentages and theoretical probability.
Intentionality…
The purpose of this assessment is for students to demonstrate their understanding of the following big ideas.
- A part of a whole represented as a percentage is a part-whole ratio whose whole is 100;
- A percentage is one of infinitely many equivalent part-whole ratios in a ratio relationship;
- A percentage can be used to scale in tandem and reveal an infinite number of equivalent ratios in a ratio relationship;
- Partitive division can be used to divide a percentage by 100 percent to reveal a rate for the proportional relationship.
The independent assessment will allow students to demonstrate concepts and skills related to the following learning goals:
- I can represent a ratio as a fraction.
- I can represent a ratio as a percentage.
- I can demonstrate an understanding of equivalence.
- I can demonstrate an understanding of theoretical probability.
- I can plot the likeliness of an outcome on a 0 to 1 number line.
- I can determine an unknown quantity within a ratio when given sufficient information about the relationship between the two quantities.
Students might write and/or model their answers independently. Students can also be interviewed by their teacher.
An alternative assessment opportunity should be offered if this tool will not successfully capture what the student knows, understands or can do.
