Quickly name 15 items that could be purchased at the grocery store. Hurry them toward the door, then have them stop and name all the items you needed. Use this exercise as a lead-in to a discussion of making lists and ask for examples of other lists. Have students make a list of names and phone numbers that are frequently called or are important. Have a discussion of headings or categories that the numbers might fall under.
Students rewrite the list, using the headings to group numbers for easier reference.
Students can take the list home to be added to and to use at home.
