U5L2 Rates Activity WorksheetName: ___________________________________Standard Goal (Green Level):Students will calculate and write rates, equivalent rates, and unit rates.Advanced Goal (Blue Level):Students will carry out complicated unit conversions.Highly Advanced Goal (Black Level):Students will carry out complicated unit conversions.STANDARD LEVEL ACTIVITIES – All students need to complete the activities. Calculators may be used.Directions: You will rotate through several activities today. Please find the proper section to complete at each activity.-114300158115BUBBLE GUM BLOWINGAssign a counter, a timer, and a blower. Blow as many bubbles as you can in 30 seconds.Rotate through these roles until everyone has had a chance to blow their own bubbles.Answer the questions below based on the data that was collected when you were blowing the bubbles.Write a ratio comparing the number of bubbles and the number of seconds. _____________________________Find your rate of bubbles per second. _______________________________. Show your work pare your results with the rest of your group members. Explain how the rate indicates which person ‘won’.00BUBBLE GUM BLOWINGAssign a counter, a timer, and a blower.

The sighters find the touch spot and share the result with the jumper. Jumpers will jump two times and record both measurements to the right.Rotate through these roles until everyone has had their turn.Choose your best jump and answer the questions below based on that data.What is the ratio of height jumped to height of jumper? _________________________________Find the rate for centimeters jumped per cm of your height.

You are not allowed to push your car down the track; just let it go.Record the data below:How long, in seconds, did it take your car to go from start to finish? ____________________________What is the time to distance rate of your car? ____________________________What is the unit rate (time to distance) of your car? _________________________________. Show your math work below.If the track had the same proportions, but was 1000 meters long, what would the rate be in km/hour. How long would it take your car to get from the start to the finish? Show your math work below. Show the math steps you used to calculate your answer for #2.00RACING CARSEach member of your group will race a small Hot Wheel racecar down the same track (distance from start to finish = 465cm).When it’s your turn to race, make sure you align the front of the racecar with the starting point, and arrange someone else to time your car from start to finish.
