Teaching measurement to young children can be tricky. If you hand a 5-year-old a standard ruler with tiny lines and confusing numbers, they will likely get frustrated. The abstract concepts of “inches” or “centimeters” mean nothing to them yet.
That is why, in early childhood education, we always start with non standard measurement.
By using concrete, everyday items instead of rulers, children learn the logic of measurement before worrying about the units. In this guide, we will walk you through the progression of skills needed to master this concept, using fun activities like measuring with objects found right in your classroom or home.
Start Small with Consistent Units
The first rule of measurement is that your “unit” must stay the same size. You cannot measure a table with a big rock and a small rock mixed together!
To teach this concept, we recommend starting with measuring with paper clips. Paper clips are fantastic because they are readily available and identical in size. They act as a bridge between simply comparing sizes and using a real measuring tool.
Once your students master counting loose clips, you can challenge them with the “Paper Clip Ruler” activity. Here, the question changes from “count the clips” to a more analytical how long is it? This prepares their brains for reading a number line later in school.
Mastering the “No Gap” Rule
After paper clips, it is time to move to rectangular units. This is where measuring with blocks (like Unifix cubes or Lego bricks) becomes essential.
Unlike rounded objects which might leave spaces, blocks fit snugly side-by-side. This is the perfect opportunity to teach the “No Gaps, No Overlaps” rule. Whether you are measuring a pencil or a toy robot, measuring length requires placing units in a straight, continuous line from start to finish.
Get Moving with Body Math
Math doesn’t have to happen just at a desk! Children learn best when they move their bodies. This is where “Kinesthetic Learning” comes into play.
Take the lesson to the floor and try measuring with shoes. Have students walk heel-to-toe to measure the length of a rug or the distance from the door to their desk. This activity helps them visualize larger distances and understand why a “giant step” gives a different number than a “baby step.”
Height, Length, and Estimation
Measurement isn’t just about how long something is lying down. It is also about how tall something stands up.
It is important to teach the difference between measuring height (vertical) and length (horizontal). You can practice this by comparing a ladder standing up versus a snake lying down.
Finally, before you let them measure, always ask them to guess first! Using estimation worksheets builds “number sense.” It encourages children to look at an object and make a reasonable judgment before checking their answer with blocks or clips.
Conclusion
From counting paper clips to walking out distances with shoes, these activities build a rock-solid foundation for future math success. Once a child understands how to measure with these fun tools, using a standard ruler becomes easy.
