  2. Volume 18-1

  3. You have already learned how to measure the area of plane (2-D) figures. Today you will learn how to measure the amount of space inside solid (3D) figures.

  4. Customary Units of Capacity 18-2

  5. You have already learned how to measure the volume of solid figures. Today you will learn how to measure how much a container holds. • This container holds about a cup. What other containers hold about one cup? • Pint? • Quart? • Gallon?

  6. Capacity • The amount of liquid a container will hold

  7. 1 cup (c)= school milk • 1 pint (pt)= small ice cream • 1 quart (qt) = orange juice carton • 1 gallon (gal)= gallon of milk

  8. 2 cups = 1 pint • 2 pints = 1 quart • 4 quarts = 1 gallon

  9. Let’s Practice!

  10. Choose the best estimate • 1 c • 1 qt

  11. Choose the best estimate • 3 pt • 3 gal

  12. Choose the best estimate • 1 pt • 1 gal

  13. Choose the best estimate • 1 c • 1 pt

  14. Choose the best estimate • 1 c • 1 pt

  15. Choose the best estimate • 2 pt • 2 qt

  26. Which measurement best describes the capacity of a juice box you might bring with your lunch? • 1 cup • 1 pint • 1 quart • 1 gallon

  27. Units of Weight 18-3

  28. You have learned how to measure the capacity of a container. Today you will learn how to measure how heavy an object is. What objects could be about as heavy as this textbook? The weight of an object is a measure of how heavy the object is or how strong gravity is pulling down on an object.

  29. Weight • a measure of how heavy the object is or how strong gravity is pulling down on an object.
