Using Rulers in Math

In just a few weeks, many students will begin testing.  One of the greatest challenges students have is lining up the ruler to an object properly.  I have a strategy that works well.  Use two cups.  Write numbers on one cup to look like a ruler.  Draw an arrow on the second cup. Stack the cups as shown.

Students practice aligning the cup with the arrow.  This makes them more aware of how they align their rulers.  It works like a charm.
