LESSON 2: HOMEWORK
Notes or additional instructions based on whole-class discussion of homework assignment:
Part I: Use the table below to record your notes about the comparative weights of different fruit combinations and write their unit rates. You need to go online to the balance scale in the Lesson “Rates and unit rates” in the topic Mindset, motivation, and algebraic thinking to complete the table.
Fruit on left side
=
Fruit on right side
Write as a unit rate
in two ways
Example: 3 Limes
=
2 Oranges
1 1/2 limes/orange or
2/3 of an orange/lime
4 strawberries
=
=
2 limes
4 oranges
=
=
1 lime
1 orange
=
Part II: Read the following elevator problem and answer the questions.
Elevators A and B travel at different constant rates. Elevator A takes 6 seconds to travel 4 floors. Elevator B can travel 3 floors in 5 seconds.
__MCE_ITEMMCE_ITEM__1. Each elevator starts at the ground floor. If each elevator continues moving at its current speed, which elevator will arrive at the 30th floor first? Show how you figured out the solution.
__MCE_ITEMMCE_ITEM__2. Which elevator is faster? How can you compare their speeds?
Part III: This graph represents the relationship between the number of students in your class and the total number of dogs they own.
__MCE_ITEMMCE_ITEM__1. Label the axes and write the rate. dogs/student
__MCE_ITEMMCE_ITEM__2. If this rate remained constant, how many dogs would there be if there
were 36 students in the class?
__MCE_ITEMMCE_ITEM__3. How would your answers to questions 1 and 2 differ if you had labeled
your axes differently?
