Fragments and Run-Ons Worksheets

About this resource

A sentence stops too soon, or three of them run together with no break at all, and a child who has only ever practiced "find the fragment" has never had to tell a run-on from a perfectly good compound sentence. This is a full fragments-and-run-ons kit for second grade: a three-way sort — complete sentence, fragment, or run-on — practiced six different ways, with room to work on every writing page.

EVERYTHING INSIDE (35 pages)

• 16 student pages in 7 page types (below), each with a big "My name" line and one short instruction
• 90 sentences, every one invented, real English, read back before it was used
• The three answers, defined in kid words on the Helper page: complete (one idea, correctly punctuated), fragment (missing a who or a verb), run-on (two or three ideas with no correct break)
• 18 cut-and-glue sentences, nine a page, in a block that takes 4 straight cuts
• 1 rules page for the teacher (with a blank line for your program's own wording), 5 answer keys generated from the same data as the pages
• 1 tracker (14 rows), 1 class progress grid, 1 team note, 1 home page, 1 filled example (an invented student), 1 phrase bank (17 starters)
• 1 binder cover and 6 divider tabs with a spine label to cut out
• Start Here, a how-to-read-a-page page, and a back page

THE SIX PRACTICE FORMATS, PLUS A HELPER (dots show the level, never color)

1. What's the Difference? (1 dot) — what complete, fragment and run-on look like, in kid words, one example of each.

2. Circle It! (1 dot, 3 pages) — read a sentence, circle complete, fragment, or run-on.

3. Sort It! (2 dots, 2 pages) — cut nine already-complete sentences from a 3 by 3 block (four straight cuts) and glue each under complete, fragment, or run-on.

4. Fix the Fragment (2 dots, 3 pages) — a fragment is missing a who or a verb; the child adds the missing part and writes the complete sentence.

5. Fix the Run-on (2 dots, 3 pages) — two or three ideas run together; the child adds a stop, or a comma and a joining word, and writes it right.

6. Write the Word (3 dots, 3 pages) — read a sentence with no options printed, write complete, fragment, or run-on.

7. My Three Sentences (3 dots, 1 page) — write one complete sentence, then write a fragment and a run-on on purpose and fix both.

Sentences are grouped in sets (A, B, C) so a child never meets the same sentence twice on one page type.

Built For The Child Holding The Page

A big "My name" line, one short instruction, large rounded letters, and writing boxes on primary lines at least 0.62 inch tall. Nothing on a student page is written for an adult. Cutting is limited to Sort It!: nine pieces a page, touching edge to edge, each at least 2.3 inch wide and 1.35 inch tall.

Type In, Or Print

The name and date lines, the tracker, the class grid, the team note, the home page and the rules-page note box are type-in fields in any PDF reader. The letters a student writes in the boxes are pencil work. This is a fillable PDF; it is not a Google Slides or PowerPoint file.

Who This Is For

Second grade classrooms, self-contained and resource rooms, and any teacher working with an older student who still mixes up a fragment, a run-on and a correct compound sentence. The home page sends the same job to a family; the team note hands off what changed since the last meeting.

What This Is, And What It Is Not

Complete-sentence, fragment and run-on classification practice with the record-keeping around it. It is not a probe, a goal bank or a score sheet, not a writing assessment, and not a claim about any student's age or rate of progress. Complex sentences and subordinating words (because, when, although, since, while, if...), the other coordinating conjunctions (nor, yet), and semicolons are not practiced; the rules page says so and leaves a line for your program's own wording. A comma splice (two complete ideas joined by only a comma, no joining word) is scored run-on throughout this pack, a stated grading convention, not a disputed grammar claim.
