7th Grade Math / Lesson 1: Customary Units

CUSTOMARY UNITS
What will we be learning in this lesson?


  • In this lesson, you will review measurements in the English system.

    Vocabulary words are found in this purple color throughout the lesson. Remember to put these in your notebook.


CUSTOMARY UNITS


  • Measurements come in many forms. You can measure lengths, volumes, even weights.
  • Each of these attributes have their own units.
  • Lengths can be measured in inches, feet, yards, or even miles.
  • Volumes can be measured in fluid ounces, cups, pints, quarts, and gallons.
  • Weights can be measured in ounces, pounds, and tons.
  • This section will review changing units within the measuring system.


CUSTOMARY UNITS
Lengths


  • Here is a table that shows the equivalent units of length. Use this table to change the following measurements.

Lengths


  • To solve these, you could set them up as proportions

Volumes


  • Here is a table that shows the equivalent units of volume. Use this table to change the following measurements.

    100 gal = _____ qt       160 pt = _____ c

    32 qt = ______ gal       240 fl oz = ______ c

Weight


  • Here is a table that shows the equivalent units of weight. Use this table to change the following measurements.


    9 lb = _____ oz           10 t = _____ lb
    48 oz = ______ lb       6,000 lb = ______ t


CUSTOMARY UNITS
Weight


 


 

                    9 lb = 144 oz                                   10 t = 20,000 lb
                    48 oz = 3 lb                                     6,000 lb = 3 t

  • Be careful when setting up the proportions. Be consistent in where you are placing your numbers.
  • Once your proportion is set up, remember to multiply on the diagonal of numbers that you know, then divide by the number that you did not use yet.
 


  • Can you set up the proportion to convert from one unit to another?

  • Be sure to go back to your classroom to get any homework assignments or other activities you need to attend to.
