  1. “The Need for Speed” Rate of Speed

  2. Round Table • Starting with the 1s and continuing clockwise, discuss the following two questions: 1. What are speed boats? 2. What are the many purposes of speed boats? 3. What affects the speed of speed boats? *Instant Stars are number 4s!

  3. What are speed boats? • A speed boat is defined as a motor boat capable of traveling at high speeds. • There are many different types of speedboats, but regardless of your style or budget, the primary objective of their design is speed and boating pleasure. • How much a speed boat costs depends entirely on your need and choice of style.

  4. What affects the speed of speed boats? • The type of engine/power source • Wind Speed and Direction • Water Current/Waves • Size of the boat • How low the boat sits in the water • And more!

  5. Think-Pair-Share Starting with the As discuss the following question: What is the difference between a ratio, a rate, and a unit rate? *Instant Stars are number 2s!

  6. Find the Unit Rate The following speed boat travels 360 miles in 6 hours. What is the unit rate?

  7. Find the Unit Rate The following boat travels 144 miles on 4.5 gallons of fuel. What is the unit rate?

  8. Rate of Speed The table below shows the total distance traveled by a boat riding at a constant rate of speed. How far will the boat have traveled after 10 hours?

  9. Find the Unit Rate The following speed boat travels 45.5 meters in 13 seconds. What is the unit rate?

  10. Which boat is faster? The following speed boats are known for their speed. The boat on the left traveled 328 miles in 4 hours, and the boat on the right traveled 498 miles in 6 hours. Which boat is faster?

  11. Make your own problem up! With your shoulder partner, write your own word problem involving comparing the unit rates of speed boats. Now trade with the pair across from you and solve it!

  12. Would the same elements that have an effect on speed boats have an effect on the speed of a car? • The type of engine/power source • Wind Speed and Direction • Water Current/Waves • Size of the boat • How low the boat sits in the water • And more!

  13. Finding the Unit Rate of a Car Students will work with your shoulder partner to race a toy car down the ramp. • Shoulder Partner A will release the car while Student B record the time it takes to reach the bottom. • Switch and record again. • Find the unit rates and compare. • Explain why the unit rates were the same or different?

  14. Exit Slip Explain how to find the unit rate, and explain why understanding how to find the unit rate is important when comparing speeds.
