After reading a story about a supermarket, students examine the change in supermarket jobs due to the advances in technology. Students observe two demonstrations. One simulates the checkout process at a grocery store using a cash register, and the other uses scanners that are in stores today. Students conclude which method is faster and more accurate and why.
This lesson plan is designed for teaching grades 3 and 4.
