This lesson explores how subtracting fractions can help residents understand how to make mathematical adjustments for new draws on clean energy sources.

Inquire: Students are introduced to a scenario where the energy needs of the apartment building are changing due to established families moving out and new families moving in.

Investigate: Students investigate subtracting fractions with unlike denominators and engage in guided practice with whole-group instruction.

Inspire: Students independently solve fraction subtraction word problems, and are introduced to the United Nations' commitment to clean energy goals.
