Fill in the Blanks for Class 1 English: 50 Sentences with Word Boxes and Answers

Fill in the blanks for Class 1 is probably the most common question type your child will see in English worksheets, class tests and exams. A sentence has a missing word, and a word box gives the choices. It looks easy, but it tests reading, grammar and understanding all at once, which is why it is such good practice.

Below you will find 50 ready-to-use fill in the blanks sentences in five sets: a and an, is, am and are, in, on and under, has and have, and a mixed set. Each set has a word box and answers. First, a short method that helps children stop guessing and start reading the whole sentence.

How to teach fill in the blanks for Class 1 English

Most mistakes happen because children read only the words just before the gap. Teach this four-step habit:

1. Read to the end. “The fish swims blank the water.” Your child must read the whole sentence, even the part after the gap.
2. Look for clues. Is there one thing or many? Is it I, he or they? Does the next word start with a vowel?
3. Try it out loud. “The fish swims on the water? In the water?” Hearing the sentence often tells them the answer.
4. Check and write. Read the sentence once more with the chosen word, then write it.

Practise the first few sentences of each set together, then let your child do the rest alone. For more mixed practice, see our Class 1 English worksheet with answers.

Set 1: Fill in the blanks with a or an

Word box: a, an

Rule: use an before a vowel sound (a, e, i, o, u), and a before other sounds.

1. I have ___ apple.

Answers: 1 an, 2 a, 3 an, 4 a, 5 an, 6 an, 7 a, 8 an, 9 an, 10 a

Notice sentence 2: red comes after the gap, not ball, so we use a. This is a common trick question. Our a and an worksheet for Class 1 has more practice.

Set 2: Is, am, are

Word box: is, am, are

Rule: I goes with am. One person or thing goes with is. You, we, they and many things go with are.

Answers: 1 in, 2 in, 3 in, 4 in, 5 on, 6 on, 7 on, 8 under, 9 under, 10 under

Tip: act these out with a toy and a box. Put the toy in the box, on the box and under the box while your child says the word.

Set 4: Has, have

Word box: has, have

Rule: he, she, it and one name go with has. I, you, we, they and many things go with have.

1. I ___ a new pencil.

4. The cat ___ a soft tail.
5. They ___ two kites.

Answers: 1 have, 2 has, 3 have, 4 has, 5 have, 6 has, 7 have, 8 has, 9 have, 10 has

Compare sentences 8 and 9: a spider is one, so has; dogs is many, so have. See our has and have worksheet for more.

Set 5: Mixed fill in the blanks with word box

Word box: a, an, is, am, are, in, on, under, has, have (use each word once)

1. There ___ an ant on the leaf.

Tip for mixed sets: ask your child to cross out each word in the box once it is used. When only two words are left, the last answers become easier.

Fill in the blanks for kids: make your own

Once your child has finished these 50, make more in seconds:

• Use their own life. “My name ___ Arjun.” “I ___ a red bicycle.” Children love sentences about themselves.
• Use the reader. Copy a sentence from their school reader and leave out one word.
• Sight-word blanks. Leave out a common word: “I can ___ a bird.” (see)
• Swap roles. Let your child make a sentence with a blank for you to fill.

Common mistakes to watch for

• Not reading the whole sentence. Insist on reading to the full stop.
• Copying the word wrongly. Check that the word is copied exactly from the box.
• Writing in capitals. The filled word should match the sentence: small letters unless it starts the sentence.
• Leaving blanks empty. Encourage a best guess. A try is better than a gap.

Frequently asked questions

How do I teach my child fill in the blanks?

Teach them to read the whole sentence first, try each word from the box aloud in the gap, choose the one that sounds right and makes sense, then read the sentence again before writing.

What topics come in Class 1 fill in the blanks?

Common topics include a and an, is, am and are, in, on and under, has and have, this and that, and sight words. The exact topics vary between schools.

When do we use an instead of a?

Use an before a word that starts with a vowel sound, such as an apple or an owl. Use a before other sounds, such as a ball or a cat.

Why does my child get fill in the blanks wrong even when they know the rule?

Usually because they read only the words before the gap. Ask them to read to the full stop and look for clues like one or many, or I, he or they.

How many fill in the blanks should a Class 1 child do at a time?

About 5 to 10 sentences at a time is enough. One short set a day works better than a long sheet once a week.
