Math Practice Topic: Independent and Dependent Variables

Description: Identify independent and dependent variables in equations or in contextual situations.

Adaptive Learning Progression: First learn the meaning through word problems, then apply to equations later.

Sample Levels (out of 6)

Do not put multiplication signs between a variable and its coefficient. (e.g., Use "5m" instead of "5 × m")

1.
You burn 5 calories every minute you exercise.

A. Which variable(s) are independent?
(Check all that apply.)

B. Which variable(s) are dependent?
(Check all that apply.)

C. Write an equation that expresses the situation.
Let c be the number of calories you burn.
Let m be the number of minutes you exercise.

Do not put multiplication signs between a variable and its coefficient. (e.g., Use "5m" instead of "5 × m")
