Articles Worksheet

Lesson Overview

About this worksheet

Articles – a, an, and the – are some of the smallest words in English, but choosing the right one trips up early elementary writers all the time. The two rules that decide between them are simple but easy to forget: a vs. an goes by the SOUND of the next word (a pencil, an orange, an hour because hour starts with a vowel sound), and a vs. the goes by whether the noun is being introduced for the first time or is already specific (a movie vs. the movie we watched last night). This worksheet gives first through third graders direct practice on both rules.

Section A on page 1 gives students 12 single nouns in a two-column grid. The student writes a or an in front of each one. The mix alternates clean consonant-sound nouns (a dog, a book, a tree) with vowel-sound nouns (an apple, an egg, an umbrella). One item – an envelope – is the kind of noun students often guess wrong because the first letter is unfamiliar; the answer key explains the vowel-sound logic.

Section B on page 2 raises the difficulty: each of 6 items is a complete sentence with one missing article. The student fills in a, an, or the based on both rules. The mix includes one specific-singular noun (the sun, the Earth) where only the makes sense, and a few first-mention nouns (an elephant, a movie) where a or an is the right choice.

Page 3 is a complete answer key. The Section A grid gives the one-word a or an answer; Section B gives the article plus a short parenthetical reason (vowel sound, first mention, only one). The reference box at the top of page 1 introduces all three articles, names the consonant-vs-vowel-SOUND rule, and shows four worked examples using generic pencil-orange-owl-moon content not reused in any assessed item.

How to Use This Lesson

Read the reference box aloud and slow down on the SOUND rule – say the words a pencil and an orange and listen for which one feels right. Show that the n in an is just there to make the words flow.

Work Section A item 1 together: apple starts with a vowel sound, so an apple is correct. Item 2 (dog) starts with a consonant sound, so a dog.

Assign the rest of Section A independently or in pairs. Item 9 (envelope) is the tricky one – say it out loud and listen for the vowel sound at the start.

Demonstrate Section B item 13 together: Maya saw ____ elephant at the zoo yesterday. Elephant starts with a vowel sound, so an elephant. Show item 15 (The sun is shining brightly today) – there is only one sun, so the is the right article.

Use the answer key on page 3 for self-check or aide spot-check; the parenthetical reasons help students see why each answer is correct.
