Key Concepts

  • Customary units of liquid measurement (gallon, quart, pint, cup, fluid ounce)
  • Conversion between different units of liquid measurement
  • Relationship between capacity and volume

Learning Objectives

  • Students will be able to identify and define gallons, quarts, pints, cups, and fluid ounces.
  • Students will be able to convert between gallons, quarts, pints, and cups.
  • Students will be able to differentiate between capacity and volume.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they know about measuring liquids. Show them different containers (milk carton, juice bottle, etc.) and ask them what units are used to measure the liquid inside. Introduce the idea that we will be learning about different units of liquid measurement and how they relate to each other.
  • Video Viewing (5 mins)
    Play the NUMBEROCK 'Capacity Song'. Encourage students to sing along and pay attention to the relationships between the units of measurement. Explain to them that the video may have some errors, such as the strange hair movements of the cartoon character, but the video remains educationally viable for understanding the concepts.
  • Guided Practice (10 mins)
    After the video, review the relationships between gallons, quarts, pints, and cups. Write these relationships on the board: 1 Gallon = 4 Quarts, 1 Quart = 2 Pints, 1 Pint = 2 Cups, 1 Cup = 8 Fluid Ounces. Work through a few example problems together, such as: 'If you have 2 quarts, how many pints do you have?' and 'If you have 3 gallons, how many quarts do you have?'
  • Hands-On Activity: Liquid Measurement Experiment (15 mins)
    Divide students into small groups. Provide each group with measuring cups, pints, quarts, and gallon containers (or substitute with appropriately marked containers). Have them perform the following experiments: 1. Fill a quart container with water using measuring cups. How many cups does it take? 2. Fill a gallon container with water using quart containers. How many quarts does it take? 3. Fill a pint container with water using measuring cups. How many cups does it take? Have them record their findings.
  • Discussion and Wrap-Up (5 mins)
    Bring the class back together and discuss their findings from the experiment. Review the key relationships between the units of measurement. Discuss the difference between capacity (how much a container *can* hold) and volume (how much is *actually* in the container). Ask students to provide real-world examples of when they use or see these measurements being used.

Interactive Exercises

  • Measurement Conversion Worksheet
    Provide students with a worksheet containing conversion problems. For example: * 3 gallons = ____ quarts * 8 pints = ____ cups * 2 quarts = ____ pints * 16 cups = ____ pints Have them work individually or in pairs to complete the worksheet.

Discussion Questions

  • What are some things we measure in gallons, quarts, pints, or cups?
  • Why is it important to know how to convert between different units of measurement?
  • What is the difference between capacity and volume?
  • Can you think of a time when you've had to measure liquid, like when cooking or baking?

Skills Developed

  • Measurement conversion
  • Problem-solving
  • Critical thinking
  • Collaboration
  • Application of mathematical concepts to real-world situations
