Compound Sentences and Conjunctions Worksheets

About this resource

Two short sentences, one comma, one little word — and a child who has never been taught which word to reach for. This is a full compound-sentence and conjunction kit for first and second grade: telling a one-idea sentence from a two-idea sentence, choosing the right joining word, building one sentence from two, sorting finished sentences by their word, and fixing a run-on, all with room to work on every writing page.

EVERYTHING INSIDE (35 pages)

• 17 student pages in 7 page types (below), each with a big "My name" line and one short instruction
• 86 sentences and sentence-building items, all invented, real English, read back before they were used
• The words practiced: and (adds), but (contrasts), or (gives a choice), so (shows a result), always with a comma right before the word
• 16 cut-and-glue sentences, eight 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), 4 answer keys generated from the same data as the pages
• 1 tracker (15 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. Simple, Compound and the Joining Words (1 dot) — one idea vs. two, the comma rule, and what each word does, in kid words.

2. Simple or Compound? (1 dot, 3 pages) — read a sentence, circle Simple or Compound. Includes the classic trap of a sentence that uses "and" to join two names, two actions or two things but is still one idea.

3. Pick the Conjunction (2 dots, 3 pages) — read both parts, circle the word (and, but, or, so) that fits, write it on the line.

4. Combine the Sentences (2 dots, 4 pages) — two simple sentences and the word to use are given; the child writes the one compound sentence on primary lines.

5. Sort by Conjunction (2 dots, 2 pages) — cut eight already-complete sentences from a 4 by 2 block (four straight cuts) and glue each under and, but, or or so.

6. Fix the Run-on (3 dots, 3 pages) — two ideas run together with no punctuation; the child adds a comma and a joining word and writes it right.

7. My Sentences (3 dots, 1 page) — write a sentence with each of and, but, or, so and draw one.

Sentences are grouped in sets (A, B, C, and A-D for Combine the Sentences) 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 with a picture, 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 by Conjunction: eight pieces a page, touching edge to edge, each at least 1.7 inch wide and 1.3 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

First and second grade classrooms, self-contained and resource rooms, and any teacher working with an older student who still needs to join two sentences correctly. 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

Compound-sentence and conjunction 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. The other coordinating conjunctions (nor, yet), subordinating conjunctions (because, although, when), complex sentences, semicolons and comma splices are not practiced; the rules page says so and leaves a line for your program's own wording. A short teacher note also flags that "and" and "so" can sometimes both sound reasonable in the same spot, and asks for a sense check rather than treating one word as the only possible answer.
