Another great resource from http://www.education.com/!
Check out: Measuring Shapes Worksheets Education.com
They have lots of these- shapes, letters, numbers...
These would make a fantastic Math Workstation activity. Just pre-cut the rulers, laminate the sheets and rulers.
You could add task cards that depict nonstandard measurement items to use in addition to the rulers.
The students could record the measurements with a dry erase marker, magnetic numbers, number tiles...
You could even add a response sheet to compare the different measurements students get using standard/nonstandard measurement items.
Differentiate by using only nonstandard measurement, rulers for inches, centimeters...
I'm excited! My first math workstation idea! :)
