2nd Grade Grammar Worksheets for Grades 2, 3, and 5

These 2nd grade grammar worksheets, 3rd grade grammar worksheets, and 5th grade grammar worksheets increase in difficulty by changing the kind of thinking required. Second graders practice complete sentences and basic conventions. Third graders apply agreement and expand ideas. Fifth graders edit independently, combine sentences, and control sentence variety.

Exercise 2: Combine each pair. Use the word in parentheses and create one well-punctuated sentence.

Answer Key and Teaching Notes: Explanations by Grade

Second Grade Answers

1. Exercise 1: 1. My dog likes sticks. 2. Can we feed the ducks? 3. Watch out for that puddle! The first sentence makes a statement, the second asks a question, and the third gives a warning.
2. Exercise 2: 1. sings 2. walk 3. run. A singular subject such as bird uses sings. The plural subjects we and Sam and Lee use the base verbs.
3. Exercise 3: 1. The sun came out, and the snow began to melt. 2. I can read a book, or I can draw a picture. But would also fit the first pair if the intended meaning is contrast rather than sequence.

Third Grade Answers

1. Exercise 1: 1. were 2. play 3. needs. Each refers to one puppy, so it takes the singular verb needs.
2. Exercise 2: 1. On Saturday, we visited the library. 2. Jalen packed pencils, paper, and a ruler. The commas separate an introductory phrase and items in a series.
3. Exercise 3: Answers may vary. Examples include “The rabbit hopped quickly across the yard” and “The class worked quietly in the science room.” Added details should make the original ideas more specific.

Fifth Grade Answers

1. Exercise 1: Last Saturday, our class visited the city museum. We saw fossils, maps, and a model of a volcano. It was the most exciting exhibit. The past-tense verb visited matches last Saturday, and the run-on is divided into two sentences.
2. Exercise 2: 1. After the storm ended, the players returned to the field. 2. Although Nora finished her research, she presented it to the class. The subordinating conjunctions connect the ideas; the introductory clauses require commas.
3. Exercise 3: 1. Fragment: Because the bell rang, the students packed their books. 2. Run-on: The trail was steep, so we slowed down. A fragment lacks a complete thought, while a run-on needs punctuation or a joining word.
