Lesson objective: Use percents to compare relationships based on different totals in a real-world context.

This lesson provides an opportunity for students to apply their knowledge and understanding of percents to a real-life situation. Students are asked to calculate and compare individualized percent daily values based on the consumption of certain portions of milk.

Key Concept students will use: 

  • Percent is a way to compare relationships that are not based on the same whole by standardizing each comparison to 100.

Skills students will use:

  • Proportional reasoning (Grade 7, Unit 2)
  • Using double number lines to find percent values

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they make sense of the quantities and their relationships that are involved in completing this task.

Key vocabulary: 

  • double number line
  • percent
  • ratio
