  1. 11/30/09 Compare Decimals #1 LT: I will learn to compare and order decimals. New trimester! Start with lesson #1 again. Today’s Plan: -New Trimester -Lesson -Assignment Learning Target: -I will learn to compare and order decimals.

  2. 11/30/09 Compare Decimals #1 LT: I will learn to compare and order decimals. • Warm Up: • Write each decimal as a fraction in lowest terms. (You may use your fraction, decimal, percent wheel.) • 0.01 B) 0.1 C) 0.33 • D) 0.25 E) 0.66 F) 0.4 Today’s Plan: -New Trimester -Lesson -Assignment Learning Target: -I will learn to compare and order decimals.

  3. 11/30/09 Compare Decimals #1 Place Value 1,000 100 10 1 0.1 = 0.01 = 0.001 = 1 1,000 1 100 1 10 Place Value: · Place Thousands Hundreds Tens Ones Tenths Thousandths Hundredths If 1 meter = 1.00 what would .5 be? .01? .06? .56? .001? Today’s Plan: -New Trimester -Lesson -Assignment Learning Target: -I will learn to compare and order decimals.

  4. Comparing and Ordering Rational Numbers 3-10 Course 2 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.

  5. 11/30/09 Compare Decimals #1 Today’s Plan: -New Trimester -Lesson -Assignment Learning Target: -I will learn to compare and order decimals.

  6. Comparing and Ordering Rational Numbers 3-10 Course 2 Additional Example 2: Comparing Decimals Compare the decimals. Write < or >. 0.427 0.425 Line up the decimal points. 0.427 7 The tenths and hundredths are the same. 0.425 5 Compare the thousandths: 7 > 5. 0.427 > 0.425

  7. Comparing and Ordering Rational Numbers 3-10 Course 2 Try This: Example 2 Compare the decimals. Write < or >. 0.535 0.538 Line up the decimal points. 0.535 5 The tenths and hundredths are the same. 0.538 8 Compare the thousandths: 5 < 8. 0.535 < 0.538

  8. Comparing and Ordering Rational Numbers 3-10 0 0.2 0.4 0.6 0.8 1 Course 2 Additional Example 3: Ordering Fractions and Decimals Order the numbers from least to greatest. 4 5 , 0.93, and 0.9 Write as decimals with the same number of places. 4 5 = 0.80 0.93 = 0.93 0.9 = 0.90 Graph the numbers on a number line. 0.93

  9. Comparing and Ordering Rational Numbers 3-10 0 0.2 0.4 0.6 0.8 1 Course 2 Additional Example 3 Continued Order the numbers from least to greatest. 4 5 , 0.93, and 0.9 The values on a number line increase as we move from left to right. 0.80 < 0.90 < 0.93 Place the decimals in order. 4 5 , 0.9, 0.93 0.93

  10. Comparing and Ordering Rational Numbers 3-10 0 0.2 0.4 0.6 0.8 1 Course 2 Try This: Example 3 Order the numbers from least to greatest. 3 5 , 0.84, and 0.7 Write as decimals with the same number of places. 3 5 = 0.60 0.84 = 0.84 0.7 = 0.70 Graph the numbers on a number line. 0.84

  11. Comparing and Ordering Rational Numbers 3-10 0 0.2 0.4 0.6 0.8 1 Course 2 Try This: Example 3 Continued Order the numbers from least to greatest. 3 5 , 0.84, and 0.7 The values on a number line increase as we move from left to right. 0.60 < 0.70 < 0.84 Place the decimals in order. 3 5 , 0.7, 0.84 0.84
