Grade 2 Mathematics Module 3, Topic F

Type: Lesson/Unit Plan


Module 3, Topic F will make use of number disks which make the comparison of numbers very easy. More than and less than lead to the addition and subtraction in the next module. In Lesson 16, students compare using the symbols <, >, and = on the place value chart. Next, students advance to comparing different forms (2.NBT.4), and finally, in Lesson 18, they apply their comparison and place value skills to order more than two numbers in different forms.

Content Standard(s):
MA2019 (2019)
Grade: 2
9. Compare two three-digit numbers based on the value of the hundreds, tens, and ones digits, recording the results of comparisons with the symbols >, =, and < and orally with the words "is greater than," "is equal to," and "is less than."
Unpacked Content
Evidence Of Student Attainment:
  • use place value terminology and concepts to explain and justify the placement of <, =, > to compare two 3-digit numbers and create true equalities and inequalities.
Teacher Vocabulary:
  • Equalities
  • Inequalities
Students know:
  • how to compare 3-digit numbers using the terminology "greater than," "equal to," and "less than".
Students are able to:
  • compare 3-digit numbers using place value concepts.
  • justify their reasoning as they compare numbers.
Students understand that:
  • the three digits of a 3-digit number represent groups of hundreds, tens, and ones.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.2.9.1: Define greater than, less than and equal to.
M.2.9.2: Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
M.2.9.3: Arrange two-digit numbers in order from greatest to least or least to greatest.
M.2.9.4: Identify zero as a place holder in two-digit and three-digit numbers.
M.2.9.5: Model using >, =, and < symbols to record the results of comparisons of two two-digit numbers.
M.2.9.6: Select numbers on a number line that are more than, less than or equal to a specified number.
M.2.9.7: Match the words greater than, equal to and less than to the symbols >, =, and <.
M.2.9.8: Determine the value of the digits in the ones and tens place.
M.2.9.9: Identify sets with more, less or equal objects.

Prior Knowledge Skills:
  • Understand amount words, such as more, less, and another.
  • Become more interested in the concept of some and all.
  • Be interested in who has more or less.
  • Understand the concept of "less than" "more than".
  • Mimic counting by ones.
  • Recognize numbers from one to 100.
  • Become interested in how many objects she/he has.
  • Understand the concept of size and amount.
  • Given a set number of objects one through ten, answer the question "how many?"
  • Pair the number of objects counted with "how many".
  • Understand that the last number name tells the number of objects counted.
  • Establish one-to-one correspondence between numbers and objects when given a picture, a drawing or objects.
  • Pair a group of objects with a number representing the total number of objects in the group.
  • Count objects one-by-one using only one number per object.

Alabama Alternate Achievement Standards
AAS Standard:
