Key Concepts

  • Digit: A part of a number.
  • Place Value: The value of a digit based on its position in a number.
  • Ones, Tens, Hundreds, Thousands: The different place values we use to build numbers.

Learning Objectives

  • Students will be able to define 'digit' and identify the digits in a given number.
  • Students will be able to identify the place value (ones, tens, hundreds, thousands) of a digit in a number.
  • Students will be able to determine the value of a digit based on its place value.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about numbers. Introduce the idea that numbers aren't just random, but have meaning based on where the digits are. Show the Homeschool Pop video (Place Values For Kids | Ones, Tens, Hundreds, Thousands) from the beginning (0:00) to 2:24.
  • What are Digits? (10 mins)
    Discuss the meaning of the word "digit" as a part of a number. Write several numbers on the board (e.g., 35, 128, 2023). Ask students to identify the digits in each number. Play the Homeschool Pop video from 2:24 to 2:49.
  • Exploring Place Value (15 mins)
    Introduce the place values: ones, tens, hundreds, and thousands. Use base-ten blocks (if available) to visually represent each place value. Explain how the position of a digit determines its value. Play the Homeschool Pop video from 2:49 to 7:03.
  • Practice and Quiz (15 mins)
    Work through several examples together, identifying the digit in each place value. Have students work independently or in pairs on practice problems. Have students take the multiple choice and fill in the blank quiz to assess understanding.

Interactive Exercises

  • Place Value Chart
    Provide students with a place value chart (ones, tens, hundreds, thousands). Give them a number and have them write each digit in the correct place value column.
  • Digit Value Game
    Call out a number and a place value (e.g., "In the number 3,456, what is the value of the digit in the hundreds place?"). Students respond with the value (e.g., "400").

Discussion Questions

  • How does the place value of a digit change its value?
  • Why is understanding place value important?
