A student made this mistake:
Mistake: Dividing the wrong way (number of units ÷ total).
1. What did the student do wrong?
2. Fix it. Show the correct work.
Hint for the fix: Unit rate is total ÷ number of units, so the answer is 'amount for 1'.
1. A runner goes 100 meters in 4 seconds. Find the meters per second.
2. 3 notebooks cost $15. Find the price per notebook.
Find two real prices at a store (or make them up) and decide the better buy using unit rates.
Show your work and explain your reasoning.
Keep separate from students.
