Jada has a rectangular board that is 60 inches long and 48 inches wide.
To convert inches to feet, I should divide by 12.What went wrong with Jada's reasoning? Explain.
The board has an area of 48 in \( \times \) 60 in = 2,880 in 2 .
If I divide the area by 12, I can find out the area in square feet.
So the area of the board is 2,880 \( \div \) 12 = 240 ft 2 .
Commentary
Since this task asks students to critique Jada's reasoning, it provides an opportunity to work on Standard for Mathematical Practice 3 Construct Viable Arguments and Critique the Reasoning of Others.
