This multi-part lesson is a great addition to any number system lesson. Students will develop a greater understanding of additive inverse and absolute value using the following resources:
*Problem of the Day: Students will begin class by taking a few minutes to answer the problem of the day. Students can write their responses in a notebook, on a loose leaf sheet of paper or on the papers provided. After a few minutes, have students check the work of another classmate, or they can check their own.
*Notes on Additive Inverse + Absolute Value: Work together as a class to fill in all of the blanks on the notes page and discuss example problems.
*Match/Switch Inequality Activity: Students will need a pencil and an activity sheet to complete this activity. Cut out the individual number cards and give one to each student in the class (I would suggest laminating these cards, if possible). When the teacher says “go” have the student walk around the room and trade papers with their classmates. They need to continuously trade papers with several different classmates until the teacher says “stop.” I like to play a song while the students are trading papers, but it isn’t a requirement. After being instructed to stop, the students need to pair up with a classmate. They need to write their values in the boxes provided on the activity sheet. Together, the students need to determine which inequality symbol should be placed between the two boxes. Once an appropriate amount of time has been given, say “go” and the students begin switching again. The activity sheet has enough spaces for 24 rounds, but you don’t have to complete the whole sheet.
*Additive Inverse + Absolute Value Practice: Students will need to complete the 5 problem worksheet on additive inverse + absolute value. This can be given as an individual assignment or students could work with a partner or in a group.
*Exit Slip: In the final minutes of class, have student complete their exit slip. This can be completed in a worksheet, on a loose leaf sheet of paper or on the papers provided. This is a great way to assess the level of understanding for each student in the class.
