Measuring length — whole and half inches

In this lesson, I show how to use a ruler to measure lines and other things in whole and half inches. Since this is for 1st grade, I use a special ruler that has a piece of paper taped on top which only shows whole and half inches. That way students don't have to be confused by all those little lines for fractional parts of an inch.

We measure the length of a marker pen, toy car, and Mathy my mascot. :)

Then I also show how to draw lines that are a specific length. it is easy — you just need to HOLD DOWN the ruler tightly while you draw.
