Reading a ruler

Part of Lesson Plan: **Measurements and Mathematics (updated) By Michael Drouin

Activity Overview / Details

Continue doing this dividing the paper, drawing shorter lines, and label the fraction for the 1/8 and 1/16.  Make sure you do it on your drawing on the board. 

I then explain that to read a ruler you first determine how many complete one inch increments there are. Then count the number of tick marks past the last complete inch. Then look at the visual aid you just made. Count the number of tick marks from the left. That gives you the fraction.

I tell them that I know that most feel pretty comfortable just reading the fraction direct (most do not) but for the first few problems on the work sheet please count the tick marks.
