Reflection: High Expectations WP: Identify the Constant of Proportionality - Section 1: Bell Ringer


In this lesson students were confused on how to set up the rate using the ratio within the text.  One critical light bulb moment for my students was once they identified 1 inch was asking them to use their knowledge of unit rates.  Once they equated this with unit rates and using previous understanding from identifying constant of proportionality, they were off for the races.  Coherence was critical with deeper understanding in this lesson.

WP: Identify the Constant of Proportionality

Unit 4: Proportional Relationships
Lesson 8 of 10

Objective: SWBAT identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. SWBAT represent proportional relationships by equations.

Big Idea: Students will use MP1, 2, 3, 4, and 6 to solve real world problems identifying the constant of proportionality (unit rate) in tables, graphs, equations, diagrams.
