Key Concepts

  • Integers: Whole numbers and their negative counterparts (e.g., 1, -1, 2, -2).
  • Number Line: A line that shows numbers in order.
  • Positive and Negative Numbers: Numbers greater than zero (positive) and numbers less than zero (negative).

Learning Objectives

  • Students will be able to identify integers.
  • Students will be able to locate integers on a number line.
  • Students will be able to differentiate between integers and non-integers like fractions or decimals.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students what they know about numbers. Introduce the idea of a 'number line' as a path for numbers to live on. Show a basic number line with only positive whole numbers.
  • Video Viewing (7 mins)
    Play the Khan Academy video 'Locate integers on a number line'. Pause at key points to ask questions and clarify any confusion. For instance, after the definition of integers, ask 'Can someone give me an example of an integer?'
  • Guided Practice (10 mins)
    Draw a number line on the board that includes both positive and negative numbers, as well as zero. Call out numbers (integers and non-integers) and have students point to where they would go on the number line. For example, ask 'Where does 3 go?' or 'Where does -1 go?'
  • Independent Practice (8 mins)
    Give each student a worksheet with a number line and a list of numbers. Have them circle the integers and then mark their location on the number line.
  • Wrap-up (5 mins)
    Review the concept of integers and the number line. Ask students to share one thing they learned during the lesson. Briefly introduce the idea that numbers can also be in between the integers, setting the stage for future lessons on fractions and decimals.

Interactive Exercises

  • Number Line Hop
    Create a number line on the floor with tape. Call out integers, and have students hop to the correct spot on the number line.
