First graders should measure lengths using non-standard units and begin using rulers (CCSS 1.MD.A.1-2). They should compare objects by length, express the difference, and order three objects by length. They also learn to measure in inches and centimeters.

Start by aligning the object with the zero mark (not the edge of the ruler). Practice measuring objects around the house or classroom. Worksheets with pre-drawn ruler images help students practice reading measurements without handling a physical ruler.

Height is measured vertically (how tall something is) while length is measured horizontally (how long something is). Both use the same measurement skills. Worksheets that compare objects by height and length help students understand measurement vocabulary and the concept of comparing attributes (CCSS 1.MD.A.1).
