Problem 2

  1. There are 3 bunches of grapes. Each bunch has 10 grapes. How many grapes are there? Explain or show your reasoning.
  2. There are 30 people in some cars. Each car has 5 people in it. How many cars are there? Explain or show your reasoning.
Show Solution
Solution
  1. 30 grapes. Sample responses:
    • 3×10=303 \times 10 = 30
    • 10×3=3010 \times 3 = 30
    • Diagram.
  2. 6 cars. Sample response: I counted 5, 10, 15, 20, 25, 30 and that's 6 times to get to 30. So, there are 6 cars.
