  1. DO NOW (5 min) True or False • 1 ≥ 1 • 2 > 3 • 5 < 6 • 3 ≥ 1 • 2 ≤ 1

  2. Imagine • You are at McDonald’s and you have $4.77. • Big Mac value meal = $4.78 • Quarter Pounder Meal = $4.80 • Chicken Nuggets Meal = $4.76 • Which meal can you buy?

  3. I can compare decimals with inequality signs

  4. Comparing Decimals Steps 1.) Make sure the decimals have the sameplace value (digits) Example: Compare 5.1 to 5.11 2.) You can add zeros to the end of decimals without changing its value! Example: Compare 5.10 to 5.11

  5. Comparing Decimals Steps 3.) To compare decimals, line up the decimal points and compare digits from left to right until you find the place where the digits are different. 4.) Once you get to a place where the digits are different, the larger digit is the larger decimal. 5.10< 5.11

  6. 0.789 ____ 0.7895

  8. 0.7890 0.7895

  9. < 0.789 ____ 0.7895

  10. Number Line Let’s look at it on a number line! Compare 0.76 and 0.32 0 1

  14. New Partners! • On the next slide I have 20 problems. “A” has 10 problems and “B” has 10 problems. • Give your partner a high five! • If you have shorter hair, you will do “A”, if you have longer hair, you will do “B.” • You will have 5 minutes to complete your problems. • After 5 minutes, you will get together and check your partners problems. Make sure you have agreed on the correct answers. • I will call on a person to answer each question. You must answer for letter A AND B. So make sure you agree with your partner’s problems!
