Non Standard Units Practice Activities
Printable preschool and kindergarten activities for measuring length and height with everyday non-standard units like blocks, cubes, clips, and counters.
Practice that builds confidence
Building measurement sense before rulers
These preschool and kindergarten measurement worksheets help children explore length, height, and size using non-standard units instead of rulers. Children practise comparing objects, lining up same-sized units, counting how many units long or tall something is, and using words like longer, shorter, taller, and equal.
The printable activities include picture-based measuring tasks, object comparisons, counting units, and simple recording pages. They are designed for early learners who are still building one-to-one counting, visual comparison, and careful placement skills before moving on to inches or centimeters.
Non-standard units let young children understand what measurement means before they use numbered tools. A pencil might be 6 cubes long, a toy car might be 4 blocks long, and a crayon might be shorter than a row of counters. The focus is not on exact standard measures but on the idea that equal units can describe and compare size.
What children practise on the pages
These worksheets move from simple visual comparison to counting repeated units. Children may decide which object is longer or taller, match objects to rows of units, count blocks beside a picture, or draw and record a measurement. The pages support vocabulary such as length, height, longer, shorter, taller, smaller, same, unit, measure, compare, and estimate.
A simple parent routine
Choose one worksheet and gather one type of unit, such as linking cubes, paper clips, buttons, or small blocks. Ask your child to place the units from one end of an object to the other, touching but not overlapping. Count aloud together, then say the full measurement: “The spoon is 7 cubes long.” Repeat with a second object and ask, “Which is longer? How do you know?”
Classroom uses for teachers
Teachers can use these printables in measurement centers, small groups, morning tubs, or follow-up practice after a hands-on lesson. They work well with real classroom objects such as glue sticks, name cards, crayons, and books. Students can first measure with manipulatives, then complete the worksheet to connect the concrete activity to a picture or written response.
Common errors to watch for
Children often leave gaps between units, overlap units, mix different-sized units, or start measuring away from the object’s edge. Some count the object instead of the units beside it. Encourage them to check: same unit, straight line, no spaces, no overlaps, start at the end, count each unit once.

Helpful answers
Frequently asked questions
What are non-standard units in preschool and kindergarten measurement?
Non-standard units are everyday objects used to measure, such as cubes, blocks, paper clips, buttons, or counters. Children use them to describe how long or tall something is before learning to measure with rulers.
Why should children measure with blocks or clips before using a ruler?
Blocks and clips make measurement visible and hands-on. Children can see that measurement means repeating equal units from one end of an object to the other, which prepares them for standard units later.
What skills do these non-standard measurement worksheets practise?
Children practise comparing length and height, placing equal units in a row, counting units accurately, using measurement vocabulary, and recording simple measurements.
How can I use these worksheets at home?
Give your child one kind of unit, such as cubes or paper clips, and have them measure a real object before completing the matching worksheet. Ask them to say the measurement aloud and compare it with another object.
What mistakes should I correct during non-standard measurement?
Watch for gaps, overlaps, mixed-size units, and starting away from the object’s edge. Remind children to use the same unit each time, line units up neatly, and count each unit once.
