Key Concepts

  • Place Value: Understanding that a dime is worth 10 cents (tens place) and a penny is worth 1 cent (ones place).
  • Adding Two-Digit Numbers: Adding the ones place first, then the tens place.
  • Using Money as a Model: Using dimes and pennies as visual aids to represent and add numbers.

Learning Objectives

  • Students will be able to identify the value of dimes (10 cents) and pennies (1 cent).
  • Students will be able to add two-digit numbers using dimes and pennies as a visual aid.
  • Students will be able to apply addition skills to solve real-world problems (like buying items at a store).

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they have ever been to a store and bought something. Discuss how money is used to pay for items. Introduce the concept of a 'receipt' and what information it provides (store name, items purchased, prices, and total).
  • Video Viewing (7 mins)
    Watch the YouTube video 'Grade 1: Math Lesson # 75 AMERICAN Adding Two-Digit Numbers Using Dimes And Pennies'. Encourage students to count along with the instructor as she adds the prices of the bakery items.
  • Guided Practice (10 mins)
    After the video, review the concepts of dimes and pennies. Ask questions like: 'How much is a dime worth?' 'How much is a penny worth?' Work through a couple of examples from the video together on the board, step-by-step, using real or play dimes and pennies. Emphasize adding the pennies (ones place) first, then the dimes (tens place).
  • Independent Practice (10 mins)
    Provide students with worksheets that have similar addition problems involving prices of items (e.g., a toy car costs 22 cents and a ball costs 15 cents, what is the total cost?). Have them use dimes and pennies (real or drawn) to solve the problems. Encourage students to show their work.
  • Wrap-Up (3 mins)
    Review the main concepts of the lesson. Ask students to share what they learned and how they can use these skills in everyday life.

Interactive Exercises

  • Muffin Shop Role-Play
    Set up a pretend muffin shop in the classroom. Assign roles (cashier, customer). Create price tags for different pretend muffins and treats. Have students practice buying items and adding up the total cost using dimes and pennies. You can create a worksheet with different items and prices on it to simulate a reciept. The customer role can pay the cashier for their muffins.

Discussion Questions

  • Why is it important to know how to add the prices of items when you go shopping?
  • What is easier to carry a lot of dimes or a lot of pennies if you want to equal one dollar?
  • Can you think of other real life examples when you would need to add two digit numbers together?
