Key Concepts

  • Place Value (Tens and Ones)
  • Adding 10 to a number
  • Recognizing patterns in the 100s chart

Learning Objectives

  • Students will be able to add 10 to a given number using a 100s chart.
  • Students will be able to use dimes and pennies to represent numbers and add 10.
  • Students will be able to identify the pattern when adding 10 to a number.

Educator Instructions

  • Introduction (5 mins)
    Begin by welcoming students and introducing the topic of adding 10 to a number. Briefly review the concepts of tens and ones. Show the video to the students.
  • 100s Chart Exploration (10 mins)
    After watching the video, revisit the 100s chart. Ask students to find a number and then identify the number that is 10 more. Emphasize the pattern of moving down one row on the chart.
  • Dimes and Pennies Activity (10 mins)
    Use real or play dimes and pennies. Have students represent a number with the coins and then add 10 cents (one dime). Ask them to count the new total and relate it to adding 10 to the original number.
  • Whiteboard Practice (10 mins)
    Write addition problems on the board (e.g., 25 + 10, 32 + 10). Guide students to solve the problems, emphasizing adding the 'tens' place. Encourage students to explain their reasoning.
  • Wrap-up (5 mins)
    Review the key concepts learned. Ask students to share one thing they learned about adding 10. Assign practice problems or a worksheet for further reinforcement.

Interactive Exercises

  • Number Line Hop
    Create a large number line on the floor. Have students start at a number and 'hop' 10 spaces forward, identifying the new number.
  • Coin Matching Game
    Prepare cards with numbers and cards with corresponding coin amounts (using dimes and pennies). Students match the number to its coin representation plus 10.
