1Compare and Order Rational Numbers 7th Grade MathLesson Objective:Students will compare and order fractions and decimals.
2Vocabulary Rational Number Any number that can be written as a fractionExamples: whole numbers, integers, fractions, decimals and percents
3Compare Rational Numbers Use <, >, or = to make the statement true.-5 __ 3<-4 __ -6>3-5-4-6
4Compare Rational Numbers Use <, >, or = to make the statement true.¾ __ ¼>-1 5/6 __ -1 1/6<1-11/6-1-2-15/6
5Whiteboard PracticeUse <, >, or = to make the statement true.
6Least Common MultipleIf the fractions are unlike, find a common denominator to compare them.12 x 1 = 1218 x 1 = 1812 x 2 = 2418 x 2 = 3612 x 3 = 36
7Compare Rational Numbers Use <, >, or = to make the statement true.>so>
8Whiteboard PracticeUse <, >, or = to make the statement true.
9Real World ExampleIn Mr. Huang’s math class, 6 out of 32 students own roller shoes. In Mrs. Trevino’s math class, 5 out of 29 students own roller shoes. In which class does a greater fraction of students own roller shoes?Mr. Huang6 ÷ 32 =Mrs. Trevino5 ÷ 29 =0.18750.1724
10Whiteboard PracticeThe table shows hoe much copper is in each type of coin. Which coin contains the greatest amount of copper?CoinAmount of CopperDime12/16Nickel3/4Penny1/400Quarter23/25
11Whiteboard PracticeGracia and Jim were shooting free throws. Gracia made 4 out of 15 free throws. Jim missed 6 out of 16 free throws. Who made the free throw a greater fraction of the time?
12Ordering Rational Numbers List the numbers 3.44, π, 3.14, and 3.4 in order from least to greatest.1. Write all numbers to the same place value.3.440 , 3.141, 3.140, 3.4442. Order the numbers according to directions.3.1403.1413.4403.444or3.14 , π, 3.44, 3.4
13Whiteboard Practice Order each set of numbers from least to greatest. 0.23, 0.19, 1/5-0.615, -5/8, -0.62-1.4, -11/25, -1.258/10, 0.81, 0.805
