In this activity, students are challenged to determine how much larger the principal s hand is compared to the hand size of the average kindergartner.
Students guess or formulate a hypothesis, and then collect data to support their hypothesis.
The Big Hand Challenge provides an excellent opportunity for student interaction with younger kids and with the principal. Data collection is easy since the flat, adjustable computer screen allows students to use the spreadsheet as a measurement tool. Students learn to appreciate the computer as a tool in math and science, but realize that they themselves are the problem solvers. You will need this program to access materials in PDF format.
