  • Students will be able to perform long division with a 3-digit dividend and a 1-digit divisor.
  • Students will be able to interpret remainders in division problems.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about division. Discuss the terms dividend, divisor, quotient, and remainder. Explain that long division is a method for dividing larger numbers.
  • Video Viewing (5 mins)
    Play the "Long Division Song" video from NUMBEROCK. Encourage students to sing along and pay attention to the steps of long division: Divide, Multiply, Subtract, Bring Down.
  • Step-by-Step Example (10 mins)
    Work through an example problem on the board, such as 298 ÷ 5, following the steps in the song. Emphasize each step (Divide, Multiply, Subtract, Bring Down) and explain why each step is necessary. Refer back to the song as needed.
  • Practice Problems (15 mins)
    Provide students with several practice problems, such as 145 ÷ 3, 321 ÷ 4, and 456 ÷ 7. Have students work independently or in pairs to solve the problems. Circulate and provide assistance as needed.
  • Wrap-up (5 mins)
    Review the key concepts and steps of long division. Ask students to explain in their own words how to perform long division.

Interactive Exercises

  • Long Division Board Game
    Create a simple board game where students must solve long division problems to advance. Each space on the board could present a division problem. This can be done in small groups.
  • Online Long Division Practice
    Use online resources like Khan Academy or Sheppard Software for interactive long division practice.
