We ask students to measure in fourths of an inch, yet many of the rulers we have in schools divide the inch into sixteenths – very difficult for third and fourth graders to use. Here are two “transitional rulers:” one in fourths, and another in eighths.
There are three parts to these activities:
1. A blowup of the ruler from 0 to 2, sized to fit Fraction Towers, for identification of the fractions.
2. Activities involving measuring and drawing lines in fourths, eighths, and sixteenths.
3. A legal-sized page each of 1-foot paper rulers marked in fourths, and another page of rulers marked in eighths. These can be laminated and cut with only a single cut each on a paper cutter.
These are purely measurement activities with the focus on identifying fractions and mixed numbers on an inch ruler.
Common Core Standards:
3.NF.2.a & b: “Understand a fraction as a number on the number line; represent fractions on a number line diagram.”
3.MD.4.: “Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch.”
