The grade 3 step: seven objects to measure to the nearest half inch with the 6 inch ruler at the top of the page. The half-inch marks are the middle-length lines between the numbers, so an answer can be a whole number of inches or a half, such as 3 and a half. Write halves as a fraction. Printed at 100% on US Letter paper the ruler shows true inches; measuring with the ruler on the sheet works on A4 too. These lengths are the kind of data that goes on a line plot. Page 2 is the answer key.
