Math for Monday, September 12 (Part 1)

  • Today’s Lesson: Chapter 2, Lesson 1 - Exploring One Million (Pages 32-34)
  • Learning Goals:
  • One thousand thousands are equivalent to one million.
  • Our number system is based on ten and the relationships among 1, 10, 100, 1000, and so on.
  • Tips for Converting Units
    • THINK:  Should your answer be bigger or smaller!
      • If your answer should be bigger, then you will multiply (i.e. How many cm in 2 m? 2 m x 100 cm/m = 200 cm)
      • If your answer should be smaller, then you will divide (i.e. How many km in 7000 m?  7000 m ÷ 1000 m/km = 7 km)
    • Units
      • 10 mm = 1 cm
      • 1000 mm = 1 m
      • 100 cm = 1 m
      • 1000 m = 1 km
  • Classwork: Practice Questions 1-7
