forming a large circle with students holding hands.

designating a student to start the process by squeezing the person's hand next in line.

when the student feels a hand squeeze, the student squeezes the next person's hand. This squeeze continues around the circle.

EXTENSION ACTIVITIES

Have the students estimate the time it takes to go in the other direction around the circle. Does it make a difference?

If we don't reach across the country, how far does our hand-in-hand link reach? Use a map to have students figure out cities that may be linked.

In May, Jeannie will send participating classrooms the data we collect during the month of April. Your students might want to create a database of the information, creating fields to compare the lengths that came in from each state. See you on the airwaves!
