Properties: Strategies to +/-

$0.00

The lesson introduces students to the commutative and associative properties as they relate to addition and subtraction of whole numbers.  Students will understand that when they add two numbers, the order in which the two numbers are added does not change the sum.  Remember that the sum is the answer to an addition problem or the total value.  The lesson gives students the opportunity to practice identifying which property is used, as well as using the properties to solve problems.  Interactive websites which include math games the students can play to practice these skills are included with the lesson.

Description

The lesson introduces students to the commutative and associative properties as they relate to addition and subtraction of whole numbers.  Students will understand that when they add two numbers, the order in which the two numbers are added does not change the sum.  Remember that the sum is the answer to an addition problem or the total value.  The lesson gives students the opportunity to practice identifying which property is used, as well as using the properties to solve problems.  Interactive websites which include math games the students can play to practice these skills are included with the lesson.

Classroom Procedure:

  1. Begin by explaining to students the word commute means to go back and forth. Going from home to school is the same distance as going from school to home.  Explain to students that associate means to be a partner.  A group or partners could be Amy, Blair, and Cody or Blair, Cody, and Amy, or another combination.  The order does not matter for the partners in the group.
  2. While reading the content pages, reinforce vocabulary and give students additional examples of both properties. Use the additional resources to enhance understanding.
  3. Introduce the notes on property strategies. Have students practice problems identifying and using each property.  Use the additional resources to enhance understanding.
  4. Have students practice problems as a class and have students verbally explain their thinking.
  5. Follow Activity page with students. Have students work individually rolling the dice to practice the commutative property.
  6. Distribute Practice page. Check and review the students’ responses as a class.
  7. Distribute the Homework page. Have students work a few problems at the beginning of the next class to reinforce the difference between the two properties.
  8. In closing, ask students to tell how to use the commutative property and how to use the associative property.
  9. Allow for responses and discussion.
