What This Standard Means
What Students Need to Do
- Students measure the length of solid objects with a ruler. They record the lengths in centimeters in a digital table or bar chart, then compare the objects using the numbers.
What Mastery Looks Like
- A student lines up one end of an object with 0 and reads the mark at the other end. They can use two recorded lengths to say which object is longer and by how many centimeters.
Common Misconceptions
- Some students start at the ruler's edge or the 1 mark instead of 0. Others count marks instead of centimeter spaces, or compare measurements made in different units.
How to Assess It
- Give each student a 9 cm and a 12 cm cardboard strip, a ruler, and a two-row digital table. Ask them to record both lengths and write which strip is longer and by how many centimeters.

Ways to Teach It
Pairs measure a glue stick, pencil, and eraser with a centimeter ruler, then enter the lengths in a shared spreadsheet to make a bar chart.
Show the class bar chart and ask, 'Which object is longest, and how many centimeters longer is it than the shortest?'
Play measurement match: partners measure four craft sticks and match each one to a card showing its length in centimeters.
Measure the inside length of a pencil box and two pencils, then record the lengths in a tablet table to decide which pencils fit.
