Verb "To Be" worksheet with sentences to complete using AM, ARE, IS.

Let’s go through each sentence one by one. We need to pick the correct form of “to be” — either am, are, or is — based on who or what we’re talking about.

Here’s a quick reminder:
- Use am with “I”
- Use is with he, she, it, or any single person/thing (like Jack, the dog)

Now let’s fill in the blanks:

1. I ___ happy! → “I” always goes with am → I am happy!

2. You ___ scared. → “You” takes are → You are scared.

3. He ___ small. → “He” is singular → use is → He is small.

5. It ___ brown. → “It” is singular → use is → It is brown.

6. We ___ young. → “We” is plural → use are → We are young.
