Reflection: Quizzes Show what you know about rates - Section 3: Quiz

 

For this quiz, I wanted to assess how students could set up and manipulate rates, rather than whether they could multiply and divide with decimals.  For this reason, I allowed students to use calculators.  I required them to show all of their work, even the work completed on the calculator. Once I graded the quiz, I passed them back to students to look over and correct.

Some students struggled with problem 3 including the graph about Tom’s driving.  I found that these students had difficulty finding a rate on the graph that could help them calculate the amount of time it would take to drive 120 miles.

Many students struggled with problem 5 about the increasing temperature.  The most common mistake involved students creating a rate of 82 degrees/20 minutes and then simplifying it to 4.1 degrees/minute.

Many students did well with problem 6 comparing Paul and Jackson’s gas mileage.  Some students found unit rates for both cars and then compared them. Other students multiplied Jackson’s gas mileage by 6/6 to create a rate comparing the amount of miles traveled using 12 gallons of gas.  In order to get full credit, I expected students to have a clear explanation explaining that Jackson’s car has the better gas mileage because he can travel a longer distance with the same amount of gas.
