What is learned: The students hear the numbers and whether the weight is too much or not enough. They also learn to weigh an object.
Getting the most out of the activity: Start by putting the largest weight on the scales first.
Group activities: Let the student tell which weight to put on the scales or take off. Find a real scale and let them weigh different objects in the classroom.
