Prefix Worksheets Un and Re

About this resource

Un means not or the opposite. Re means again. Unhappy, unlock, reread, rebuild: the small word at the front changes what the whole word means, and children see it best when they can build, match, split and glue the words with their own hands. This is a full un- and re- kit for first and second grade, with word tiles a child can read, primary handwriting lines, and room to work on every writing page.

EVERYTHING INSIDE (36 pages)

• 19 student pages in 8 page types (below), each with a big "My name" line and one short instruction
• 47 words (25 with un, 22 with re), each one un or re plus a base word, with the split for every word on a word-list page for the teacher; 102 practice items on the sets of six
• 18 different sentences (Use It), all invented and short
• 12 cut-and-glue words, six a page, in a block that takes 3 straight cuts
• 1 word list, 3 answer keys generated from the same word table as the pages
• 1 tracker (17 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 EIGHT PAGE TYPES (dots show the level, never color)

1. Prefix Helper (1 dot) — un + happy = unhappy, re + read = reread, and the same base, do, with each prefix: undo and redo.

2. Build It (1 dot, 3 pages) — a prefix tile, a base tile, a plus sign, and the new word in light gray on primary lines for the child to trace.

3. Match the Meaning (1 dot, 3 pages) — six clues on the left ("not lucky", "read again"), six words on the right; the child draws a line to join a clue to its word.

4. Which Prefix? (2 dots, 3 pages) — a base word with the chips un and re; the child circles the one that makes a real word and writes it on primary lines.

5. Split It (2 dots, 3 pages) — a word; the child writes the prefix and the base in two boxes on primary lines.

6. Glue It (2 dots, 2 pages) — six clues, each with a prefix and an empty glue slot; cut six base words from a 3 by 2 block (three straight cuts) and glue the one that fits each clue.

7. Use It (3 dots, 3 pages) — a word box and six sentences with an empty box; the child writes the word that fits.

8. My Words (3 dots, 1 page) — unhappy, rewrite, unplug: write a sentence with each word and draw a picture.

Words come in sets of six (A, B, C). No two pages have the same six words. On Which Prefix? and Glue It, where a child chooses between un and re, every base takes only one of the two (happy takes un, count takes re), so there is one right answer. Words that could take either prefix, such as lock, tie, pack and load, are used only where the prefix is printed for the child.

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 0.66 inch tall. On Build It, Match the Meaning, Split It and the word list the prefix is teal and the base word is coral, so a child can see which part is which. Nothing on a student page is written for an adult. Cutting is limited to Glue It and the binder tabs; Glue It has six pieces a page, touching edge to edge, each wider than 1.5 inches and taller than 1.2.

Type In, Or Print

The name and date lines, the tracker, the class grid, the team note, the home page and the word-list 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 the prefixes un and re. The home page sends the same job to a family; the team note hands off what changed since the last meeting.
