Ratio and Percent

Strand: Number
Outcomes: 5 and 6

Step 4: Assess Student Learning

Guiding Questions

• Look back at what you determined as acceptable evidence in Step 2.
• What are the most appropriate methods and activities for assessing student learning?
• How will I align my assessment strategies with my teaching strategies?

Sample Assessment Tasks

In addition to ongoing assessment throughout the lessons, consider the following sample activities to evaluate students' learning at key milestones. Suggestions are given for assessing all students as a class or in groups, individual students in need of further evaluation, and individual or groups of students in a variety of contexts.

A. Whole Class/Group Assessment

Examples of Whole Class/Group Assessment  

B. One-on-one Assessment

Examples of One-on-one Assessment  

C. Applied Learning

Provide opportunities for students to use their understanding of ratio and percent in a practical situation and notice whether or not this understanding transfers.

For example, ask the student to solve the following problem and explain the thinking done to solve this problem.

You are making a mixture of red and green candies that has three red candies for every two green candies. What percent of the mixture is made up of red candies?    

Does the student:

• explain that the three red candies and two green candies each represent a part of the ratio?
• know that the total of five candies represents the whole in the ratio?
• compare the number of red candies to the total number of candies?
• explain the part-to-whole ratio as , 3 to 5 or 3:5?
• change the part-to-whole ratio to percent by providing a ratio out of 100?
• explain that is equivalent to or 60%?
• apply ratio and percent to other real-world problems?
