Sentence Building Worksheets: Unscramble the Sentences
Updated November 2026 · 10 free printables
Free unscramble-the-sentence worksheets for kindergarten to 2nd grade. The words of each sentence are mixed up on colored arrow cards; kids write 1, 2, 3 and so on in the boxes under the cards to show the right order, then write the whole sentence on the line. A small picture next to each sentence gives a clue.
Kindergarten pages have four-word sentences about pets, the farm and food. Grade 1 pages have five-word sentences about bugs, ocean animals, weather and things that go, and grade 2 pages use longer sentences about space, the seasons and school. The answer key on page 2 shows the numbers and the finished sentences.

Frequently asked questions
What clues help kids unscramble a sentence?
The word with a capital letter usually comes first, and the word with the period at the end comes last. The picture tells what the sentence is about, so kids can say it out loud before they number the cards.
Can the word cards be cut out?
Yes. For younger kids, cut the arrow cards apart and let them slide the words around on the table until the sentence sounds right, then write it down.
Why is sentence building good practice?
Putting words in order teaches how English sentences work: who or what the sentence is about, then what happens. It also reinforces capital letters, spaces between words and end punctuation.
What should my child do after finishing a page?
Read each finished sentence aloud, then try writing a brand-new sentence about the same picture. Changing one word, like cat to dog, is an easy first step.
