This is a great activity for learning about past and present. It can be incorporated into a lesson or put on a shelf as an activity for when students have finished their work early. Students match a picture of past and present (for example, an old car and a new car), and glue the pictures together. Then they attach 4 of these picture-matches to hang from the mobile. This file includes three pages, one page of directions for assembling the mobile, and two pages of the print-out needed for each student.
