English Comparatives for Children: Bigger, Smaller, Longer
Use real objects to practise bigger, smaller and longer. Try clear sentence models, an interactive activity and a small comparison game at home.
Quick answer: Begin with two familiar objects. Show the difference, then model a sentence such as “This pencil is longer than that pencil.” Choose one comparison and one pattern rather than introducing every rule at once.

- Put two familiar objects side by side.
- Choose one difference: size or length.
- Model one sentence and swap roles.
- Try the same pattern with different objects.

Choose the correct form: “The red box is ___ than the blue box.”
- biger
- bigger
- more bigger
Answer and explanation
bigger: Big becomes bigger, with double g. We do not add more to bigger.
Which word means less big?
- smaller
- longer
- bigger
Answer and explanation
smaller: Smaller compares size. Demonstrate with two boxes.
Which sentence compares length?
- I feel happy.
- Where is the pencil?
- This pencil is longer than that pencil.
Answer and explanation
This pencil is longer than that pencil.: Longer compares length. Align the pencils at one end to show the difference.
Start with a visible difference
Place a long pencil and a short pencil on the same starting line. Long describes one pencil; longer compares the two. Aligning the objects avoids turning the answer into a guess about the angle of a photograph.
Begin with objects of the same kind. A toy car and a photograph of a real car shown at different scales can be confusing. Two pencils, boxes or toys make a clearer first comparison.
Use a small set of sentence models
“The red box is bigger than the blue box” identifies the larger box. “The blue box is smaller than the red box” expresses the same relationship from the other direction. “This pencil is longer than that pencil” compares length. You can use just one model initially.
British Council’s comparatives guide explains -er forms and spelling changes. Big becomes bigger, not biger. However, not every adjective takes -er. Practising these examples is a small starting point, not completion of the whole grammar topic.
Choose an object for a purpose
Prepare a box that fits only the smaller of two toys. Say “Choose the smaller toy” and let your child try. Once they choose, model “This toy is smaller.” The language helps solve a real selection problem.
In another round, use the longer of two paper strips as a bridge across a toy road. You do not need claims about strength or weight: focus on the visible length. When ready, your child can name both objects in a full comparison.
Respond to mistakes with a short model
If the child says “more bigger”, reply with “Yes, this box is bigger.” Avoid explaining every exception at the same time. In a writing task you might point out the double g; a spoken game does not have to become a spelling lesson.
If the object names are unfamiliar, begin with this one and that one while pointing. Choosing the correct object and producing the sentence independently are separate skills. Do not treat them as a single measure of ability.
Link home practice with a Stayeng lesson
Tell the teacher which objects you used and which sentence the child could say. An object-selection or room-arranging activity can reuse the pattern in a lesson. Keeping comparisons about objects rather than people’s appearance makes the task more comfortable.
The short activity below checks sentence form and meaning. Follow it with one sentence about two real objects away from the screen. It is not a CEFR level test; it helps you choose a model to practise again.
Frequently asked questions
Does every adjective take -er?
No. This guide begins with bigger, smaller and longer. Other adjectives can use different forms.
My child chooses correctly but cannot say the sentence. What next?
Accept the choice and offer a short model. Begin with a phrase such as “This one is bigger” before naming both objects.
