Free Small Medium Large Worksheets

Learning to distinguish between Small, Medium, and Large is a major milestone in preschool math. Our collection of Small Medium Large Worksheets goes beyond simple comparisons to teach children how to sequence objects based on their relative size. These printable PDFs are the perfect resource for mastering the concept of "Ordering by Size."


📏 Why Teach "Medium" Size?

Moving from two variables to three is a big cognitive leap. This category helps children understand:

  • Relative Size: Understanding that "Medium" is bigger than Small but smaller than Large.
  • Sorting Logic: Categorizing mixed items into three distinct groups. (See also: Sorting by Attribute).
  • Foundation for Comparisons: Before this, children learn Big vs. Small. This is the next level.
  • Sequencing Skills: Preparing them for more complex ordering tasks like Ordering by Length (Shortest to Longest).

How to Use These Worksheets

Start with "The Three Bears"

Relate the worksheets to the story of Goldilocks. Use terms like "Papa Bear size" (Large), "Mama Bear size" (Medium), and "Baby Bear size" (Small) to make it fun and memorable.

Sort Real Objects

After finishing a worksheet, try it with real life! Line up three shoes or three spoons and ask your child to point to the "Medium" one.
