Big Small Practice Activities
Printable preschool and kindergarten activities that help children compare objects and identify which one is big or small.
Practice that builds confidence
What children learn
These Big Small worksheets help preschool and kindergarten children build early comparison skills by looking closely at object size. Children practise using words such as big, small, bigger, and smaller while choosing, circling, colouring, matching, and sorting pictures.
The printable activities use familiar objects so young learners can focus on the size relationship, not on reading directions. Pages are designed for the Comparison unit and support visual discrimination, vocabulary, and early maths thinking.
Big and small are among the first comparison ideas children meet. In these worksheets, children look at two or more pictures and decide which object is large and which is little. The work strengthens size vocabulary, attention to visual details, and the idea that an object can be described by comparing it with another object.
How the practice progresses
Activities begin with clear pairs, such as a big ball and a small ball, where the size difference is easy to see. Children may circle the big object, colour the small object, draw a line to match similar sizes, or sort pictures into big and small groups. As they gain confidence, they learn to ignore shape, colour, or position and focus on size only.
A simple parent routine
At home, place two toys on the table and ask, “Which one is big? Which one is small?” Then switch the order or use two objects from the same category, such as two cups or two spoons. After one worksheet section, invite your child to find something bigger than a crayon and something smaller than a shoe. This links the printable page to real-world comparison.
Classroom uses for teachers
Teachers can use these pages during morning work, small-group maths, comparison centers, or follow-up after a hands-on sorting lesson. A worksheet can also become a quick language prompt: children can say, “The elephant is big” or “The mouse is small” before marking the answer. For extra support, pair the page with actual classroom objects.
Common errors to watch for
Some children choose the object they like best instead of comparing size. Others may be distracted by color, picture detail, or the position on the page. If a tall thin object and a short wide object appear, children may need help noticing which feature is being compared. Encourage them to look at the whole picture and use the words big and small aloud.

Helpful answers
Frequently asked questions
What skill do Big Small worksheets teach?
They teach children to compare objects by size and identify which object is big or small. This supports early maths language, observation, and visual discrimination.
Are these worksheets suitable for preschool children?
Yes. The activities use picture-based tasks such as circling, colouring, matching, and sorting, so preschool children can practise the concept without needing to read long instructions.
How can I help my child if they keep guessing?
Ask your child to point to both objects first, then say what they notice. Use a prompt such as, “Which one takes up more space?” before they choose big or small.
Should children learn big and small before bigger and smaller?
Most children begin with big and small because the contrast is simpler. Once they understand that, bigger and smaller can be introduced as comparison words between two objects.
How can teachers use these pages in a comparison lesson?
Teachers can introduce the idea with real classroom objects, then use the worksheet as independent practice, a small-group activity, or a center task focused on size vocabulary.
