-At home or in the classroom, challenge the child to find something that is smaller in size than the orange but weighs more (ie. a paperweight). Encourage him or her to find something that is bigger in size but weighs less (ie. a paper plate). Talk about the difference between weight and size.
-Read "The Napping House" by Audrey Wood. Talk with your child about the people and animals on the bed. Which ones are heavy? Which ones are light?
Adjust for an older child
Weigh the fruits in the scales while you are at the grocery store. Find the difference between the weights.
Adjust for a younger child
