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. CUSTOMARY UNITS Lengths To solve these, you could set them up as proportions CUSTOMARY UNITS Lengths CUSTOMARY UNITS 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 = _____ c32 qt = ______ gal       240 fl oz = ______ c

 CUSTOMARY UNITS Volumes Use proportions CUSTOMARY UNITS Volumes Use proportions CUSTOMARY UNITS 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 = _____ lb48 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

 CUSTOMARY UNITS 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.
