KS1 English Adjectives - Adding 'er' and 'est' Quiz

Practise adding er and est to adjectives

Learning how to change adjectives into comparative and superlative forms is an important step in KS1 English. Children already use describing words in speech from an early age, but writing them accurately is different. This quiz helps pupils notice how a simple adjective can change to compare two things or show the strongest example in a group. That small shift supports sentence building, vocabulary growth and confidence in everyday writing.

In the Department for Education National Curriculum, pupils are expected to develop grammatical understanding that helps them speak and write clearly. Work on adjectives fits naturally into that aim because it helps children be more precise. Instead of writing that one object is big, they can say another is bigger and a third is the biggest. That gives their language more control and more purpose.

Short grammar practice can be especially effective when it is paired with feedback. The Education Endowment Foundation toolkit associates feedback with around 6 additional months of progress, and metacognition and self-regulation with around 7 additional months. In practical terms, that means a child benefits most when they answer a question, check it, and think about why the word changed in that specific way.

Why comparatives and superlatives matter

Adding er and est is about more than spelling endings. It teaches children how to compare ideas clearly. These forms appear in stories, classroom talk, simple reports and descriptive sentences. A secure understanding helps pupils read with better comprehension and write with more precision.

• It develops awareness of how adjectives change meaning.


• It supports descriptive writing in KS1.


• It helps children compare size, speed, height and other qualities.


• It reinforces grammar through repeated example-based practice.

What this quiz helps children notice

Grammar grows faster when children can hear the difference, say the difference and then write the difference. Comparative language is a good example of that pattern.

How to extend practice after the quiz

Try asking a child to compare familiar objects at home or in class: a long pencil and a shorter pencil, a tall tower and the tallest tower, a loud drum and a louder one. This turns grammar into something visible and memorable. It also helps children understand that word endings are tied to meaning, not only to spelling rules.

This quiz gives young learners a clear route into comparative and superlative adjectives. Once children are comfortable with er and est, their descriptive writing usually becomes more confident and more exact.
