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

11/30/09 Compare Decimals #1 Today’s Plan: -New Trimester -Lesson -Assignment Learning Target: -I will learn to compare and order decimals. 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.) A) 0.01 B) 0.1 C) 0.33 D) 0.25 E) 0.66 F) 0.4

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. Course 2 3-10 Comparing and Ordering Rational Numbers

Compare the decimals. Write. Additional Example 2: Comparing Decimals 0.4270.425 0.427 0.425 0.427 > 0.425 Line up the decimal points. The tenths and hundredths are the same. Compare the thousandths: 7 5 7 > 5. Course 2 3-10 Comparing and Ordering Rational Numbers

Compare the decimals. Write. 0.5350.538 0.535 0.538 0.535 < 0.538 Line up the decimal points. The tenths and hundredths are the same. Compare the thousandths: 5 8 5 < 8. Try This: Example 2 Course 2 3-10 Comparing and Ordering Rational Numbers

Order the numbers from least to greatest. Additional Example 3: Ordering Fractions and Decimals 4545 0.93, and 0.9, 4545 = 0.80 Graph the numbers on a number line. 0 0.2 0.4 0.6 0.8 1 0.93 Write as decimals with the same number of places. 0.93 = 0.93 0.9 = 0.90 Course 2 3-10 Comparing and Ordering Rational Numbers

Additional Example 3 Continued The values on a number line increase as we move from left to right. 0.80 < 0.90 < 0.93 4545, 0.9, 0.93 Place the decimals in order. Order the numbers from least to greatest. 4545 0.93, and 0.9, 0 0.2 0.4 0.6 0.8 1 0.93 Course 2 3-10 Comparing and Ordering Rational Numbers

Order the numbers from least to greatest. Try This: Example 3 3535 0.84, and 0.7, 3535 = 0.60 Graph the numbers on a number line. 0 0.2 0.4 0.6 0.8 1 0.84 Write as decimals with the same number of places. 0.84 = 0.84 0.7 = 0.70 Course 2 3-10 Comparing and Ordering Rational Numbers

Try This: Example 3 Continued The values on a number line increase as we move from left to right. 0.60 < 0.70 < 0.84 3535, 0.7, 0.84 Place the decimals in order. Order the numbers from least to greatest. 3535 0.84, and 0.7, 0 0.2 0.4 0.6 0.8 1 0.84 Course 2 3-10 Comparing and Ordering Rational Numbers
