Same Different Size Practice Activities
Printable preschool and kindergarten comparison worksheets for identifying objects that are the same size or different sizes.
Practice that builds confidence
What children learn
These printable same and different size worksheets help preschool and kindergarten children notice how objects compare by size. Children look at pictures, name which items match in size, and identify the one that is bigger, smaller, taller, shorter, wider, or thinner when the picture supports it.
Activities include circle-the-match, color the different-sized object, draw lines to matching sizes, and simple sorting prompts. The pages build visual discrimination, early measurement language, and careful observation without requiring children to measure with rulers.
In the Preschool and Kindergarten > Comparison sequence, same and different size practice is an early step toward measurement. Children learn that objects can be alike in shape or type but not alike in size, such as two balls where one is larger, or three pencils where one is shorter. They also practise comparison words: same size, different size, bigger, smaller, tall, short, long, and wide.
How the worksheets progress
The activities begin with clear picture pairs so children can decide whether two objects are the same size or not. Later pages ask them to find the object that does not belong, match objects of equal size, or choose between similar pictures with a small size difference. This progression encourages children to slow down, scan the whole image, and compare more than one feature.
A simple parent routine
At home, start with real objects before the printable page. Put out two spoons, two blocks, or two shoes and ask, Are these the same size or different sizes? Then move to the worksheet and let your child point before marking an answer. After each item, ask them to explain with one comparison word, such as smaller or same size.
Classroom uses for teachers
Teachers can use these pages in morning work, small-group comparison lessons, math centers, or assessment folders. They also work well after a hands-on sorting tray with classroom objects. For extra language practice, have children answer in a complete sentence: The two cups are the same size, or This apple is bigger.
Common errors to watch for
Some children compare color, position, or cuteness instead of size. Others choose the taller picture even when the task asks for same size. Point to the top, bottom, and sides of the pictures and ask children to compare the space the object takes up, not just its color or location.

Frequently asked questions
What skill do same and different size worksheets teach?
They teach children to compare objects by size and decide whether pictures are the same size or different sizes. This supports early measurement language and careful visual observation.
