Number Line: A line with numbers placed in their correct position.
Opposite Numbers: Numbers that are the same distance from 0 but in opposite directions on the number line. Example: -6 and 6.
Understand Opposite Integers
Prerequisite Skill
Materials and Preparation
- Number line (classroom display or individual student handouts)
- Graph paper
- Markers or colored pencils
- Worksheet Pack (including guided practice, independent practice, exit tickets, homework, and assessment)
Learning Objectives
- Students will be able to graph negative numbers on a number line.
- Students will understand and identify opposite numbers.
- Students will demonstrate the ability to find the opposite of a given number.
Introduction
Begin the lesson by introducing the number line. Explain that the number line is a visual representation of numbers in order, both positive and negative. Draw a number line on the board and highlight the position of 0 in the center. Show how numbers to the right of 0 are positive, and numbers to the left of 0 are negative. For example, -6 is six units to the left of 0.
Explicit Instruction/Teacher modeling
Explain that opposite numbers are numbers that are the same distance from 0, but in opposite directions. Write -6 on the number line, emphasizing that it is 6 units to the left of 0. Ask students to find the number that is 6 units to the right of 0, which is 6. Highlight that -6 and 6 are opposites because they are the same distance from 0 but in different directions.
Guided Practice
Provide a worksheet that asks the student to match each number from the "Numbers" list with its opposite from the "Opposites" list. Walk around the room to check for understanding and correct any mistakes.
Independent Practice
Provide a worksheet with several numbers for students to graph on a number line. Include both positive and negative numbers. Ask them to find and graph the opposites of each number as well. Ensure the worksheet includes varied numbers for a comprehensive practice.
Differentiation
Support
- Provide additional number line visuals and manipulatives for students who need more hands-on practice.
- Pair students with peer tutors for additional support.
Extension
- Challenge students to find the opposites of more complex numbers, including decimals and fractions.
- Introduce real-world examples where understanding opposite numbers is beneficial, such as temperatures and elevations.
Assessment
Use the assessment worksheet from the worksheet pack to evaluate students' understanding. The assessment should include tasks like graphing numbers on a number line, identifying opposite numbers, and explaining their reasoning.
Review and closing
Review the concept of opposite numbers and address any common misconceptions. Ensure clarity by allowing students to ask any final questions or share observations. Summarize the key points of the lesson, reiterating how to find and graph opposite numbers on a number line.
Misconceptions
- Misunderstanding that the opposite of a positive number is another positive number.
- Confusing the position on the number line, thinking -6 is to the right of 0.
- Believing that zero has an opposite.
