Spanish students have a lot of problems with adjectives in English. Two important things that I usually highlight in class are:
1. Adjectives are always SINGULAR . I have two BEAUTIFUL children (not beautifuls)
2. Adjectives always go BEFORE the noun . I have a BLUE PEN (not pen blue).
Apart from these basic things, students always use the same adjectives to describe elements: small, big, beautiful, ugly... and in English there are hundreds of different adjectives you can use!!!
I am going to ask you some questions I would like you to answer using adjectives. Choose one or two, it's not necessary to answer all of them:
1. Describe the most important person for you.
2. How do you feel when you wake up in the morning?
3. Tell us about the best moment in your life and describe your feelings.
4. Who do you admire? Tell us why.
5. Tell us about the last book you read.
6. Describe the last party you went to.
