The standard
Use rulers to measure lengths in halves and fourths (quarters) of an inch and a whole inch.
Element 3.MDR.5.4 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Measurement & Data Reasoning strand. It sits under standard 3.MDR.5: Solve real-life, mathematical problems involving length, liquid volume, mass, and time and analyze graphical displays of data to answer relevant questions.
What students practice
True-size rulers marked in wholes, halves, and fourths print at 100 percent. Students read lengths to the inch, half inch, and quarter inch, then measure lines and draw lines of a given length with their own ruler. Every printed length sits exactly on a mark.
Where to find it
Think: the end is halfway between 4 and 5, so it is 4 and one half inches.
