In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million. Using the thematic setting of Johnny Appleseed, learners practice their number sense and estimation skills as they progress from merely guessing the number of apples in a bushel to making a reasonable estimate based on a point of reference or benchmark. Learners use data from the Michigan Apple Growers to compute and analyze the total amount of apple yield per acre. They work at centers to gain experience in visualizing the magnitude of one million apples. Learners also gain experience in using a grid as a resource to make better estimations.
