Key Concepts

  • Ounces (oz)
  • Pounds (lbs)
  • Tons
  • Conversion between units of weight

Learning Objectives

  • Students will be able to define and identify ounces, pounds, and tons as units of weight.
  • Students will be able to convert between ounces and pounds.
  • Students will be able to convert between pounds and tons.
  • Students will be able to identify real-world objects that are typically measured in ounces, pounds, or tons.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what units they use to measure how heavy things are. Introduce the terms ounces, pounds, and tons. Show a variety of objects and ask them to guess which unit would be best to measure them with.
  • Video Viewing (5 mins)
    Play the NUMBEROCK video 'Ounces, Pounds, & Tons Song ★ Customary Units of Measurement'. Encourage students to sing along and pay attention to the relationships between the units.
  • Guided Practice (10 mins)
    After the video, review the key relationships: 16 ounces = 1 pound, 2000 pounds = 1 ton. Work through example conversion problems together on the board, such as: How many ounces are in 2 pounds? How many pounds are in 3 tons? Use visual aids like scales or diagrams to help students understand the conversions.
  • Independent Practice (10 mins)
    Provide students with a worksheet containing conversion problems and real-world scenarios involving ounces, pounds, and tons. For example: A bag of apples weighs 3 pounds. How many ounces does it weigh? A truck weighs 4 tons. How many pounds does it weigh?
  • Wrap-up & Discussion (5 mins)
    Review the answers to the independent practice. Discuss any challenges students faced. Ask students to share examples of items they have encountered and what unit of measurement was used.

Interactive Exercises

  • Weight Estimation Game
    Bring in a variety of objects (e.g., a book, a pencil, a bottle of water, a small bag of flour). Have students estimate the weight of each object in ounces or pounds. Then, use a scale to measure the actual weight and compare it to their estimations.
  • Conversion Challenge
    Divide students into groups. Give each group a set of conversion problems to solve as quickly as possible. The group that correctly solves the most problems in the allotted time wins.

Discussion Questions

  • What are some things you would measure in ounces?
  • What are some things you would measure in pounds?
