LEARNER OUTCOME(S)
  • Learners will compare three-digit numbers based on meanings of the hundreds, tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
/ ASSESSMENT TOOLS/METHODS
  • Formative throughout lesson
  • Comparing Numbers Quiz – students should achieve 75% accuracy

LEARNER PRIOR KNOWLEDGE
  • This lesson follows lessonComparing Two Digit Numbers
  • Learners will need mastery of comparing two digit numbers

INSTRUCTIONAL ACTIVITIES
Lesson Comparing Two Digit Numbers should have prepared students to understand numbers by looking at place value. This lesson looks at the same skill but applied to three digit numbers
  1. Warm up with examples of comparing two digit numbers. This can be done as stations, or whole group review. In previous lessons, students are encouraged to use manipulatives like money or base ten pieces. These manipulatives are welcome in this lesson as needed, including the Greater than, Less than Reference Sheet.
  1. Demonstrate to students that the same process for comparing two digit numbers is used for comparing three digit numbers, but with the addition of hundreds place, we now look first at the number in the hundreds place. If that number is the same, move down to the tens, and so on. Students should be able to master this skill relatively quickly if they have mastered comparing two digit numbers.
  1. When students are proficient in comparing numbers, introduce the symbols >, <, =.
  1. Comparing game: give each student a note card and have them write a three digit number on it. Randomly choose students to bring their card to the board and write their numbers. Then have them use the appropriate symbol to compare. Repeat as many times as necessary. Use this opportunity to conduct formative assessment.
  1. Finish with Comparing Numbers Quiz.

DIFFERENTIATION
  • For an increased challenge, introduce higher place values
  • Pair students to be peer tutors
  • Use the Greater than, Less than Reference Sheetthat is labeled where the respective numbers go.
