Have students make their favorite number (between 1 and 10) with Unifix cubes. Have them assemble themselves with fellow students to form a graph. All of the "1's" should line up in a row, as should the "2's" and "3's" and so on. The rows should be parallel and should form a human bar graph when looked at from above. This is also a great way to begin a discussion on uniformity in graphs and the need to be consistent when graphing data.
