Bring the String 
Find the lengths of five large objects in the classroom using string. Cut off the string to indicate each length.
In a corner of the classroom, two group members hold the string against the two adjoining walls so that there is no slack. (See the figure below.) The other group member measures the distance in meters between the corner and the point at which each of the other two group members is holding one end of the string.
Use the Pythagorean Theorem to find the length in meters of the object whose string measurement you found.
Repeat the procedure for the other objects.
