What This Standard Means
What Students Need to Do
- Students line up equal-sized objects along a length, with no spaces or overlaps. They count the objects, up to 20, and state the measurement using the unit name.
What Mastery Looks Like
- A student places equal-sized units in a straight line from one endpoint to the other, with each unit touching. They count accurately and report, for example, “The pencil is 9 cubes long.”
Common Misconceptions
- Students may leave gaps, overlap units, or mix different-sized units. They may start past the object's endpoint, miscount the units, or omit the unit name.
How to Assess It
- Give each student a crayon and 20 linking cubes. Say, “Measure the crayon and write how many cubes long it is.”

Ways to Teach It
Give each pair 20 linking cubes and three classroom objects; students build a touching cube train beside each object, count, and record.
Show two cube measurements, one with gaps and one without; ask, “Which measurement is fair, and how do you know?”
Play Measure and Match: students measure picture strips with tiles, then match each strip to a numeral card from 1 to 20.
Students measure pencils with cubes and decide which pencil will fit inside a 12-cube-long supply box.
