Sample Activities:
· Given a jar with straight sides and half filled with water, students drop marbles in five at a time. After each group of five, they measure the height of the water and record in a table the number of marbles in the jar and the height of the water. The students then represent their data in a scatterplot on an x-y plane and find that the points lie almost exactly in a straight line. They draw a line through the data and use it to determine answers to questions like: How high will the water be after 25 marbles have been added? and How many marbles will it take to have the water reach the top? Activities like this one form the foundation for understanding graphs in algebra.
