- At the Math center, have students estimate the height of a particular tree in the schoolyard.
- Working in pairs, have them find the actual height. To do this, they will need to find the information to satisfy the following equation:

( height of tree )/( length of shadow of tree ) = ( height of student )/( length of student's shadow ) - Please note that the shadow measurements must be taken at the same time (sun's angle must be the same).
- This works well using string to measure the distances and heights while outside and then measuring the string once back inside.
