It is quite easy to form comparatives and superlatives in English. However, without much practice students will make a lot of mistakes.
To provide enough practice for my students I have created the following exercises. There are three gap-fill exercises where students will practise the grammar in context.

Show it to your students and explain that students first have to decide if the adjective is long or short. If the adjective is just 1 syllable, it is short. If it ends with -y, it is short. Otherwise, it is long.
Once they know whether the adjective is long or short, they can form the superlatives and comparatives correctly. With short adjectives, they add the suffixes -er or -est. With long adjectives, they add more or most in front of the adjective.
