This unique worksheet is called "Vocabulary Sudoku" because it helps students practice their vocabulary and spelling skills in a Sudoku-like puzzle.

Each puzzle includes a word bank with directions that state, "Each row, column, and box must have all the words from the word bank. Write the missing words." Below is a grid of rectangles. There are rectangles arranged three by three. Each large rectangle has two rows of three smaller rectangles for a total of six in each square. Students fill in the words from the word bank into each small rectangle. Students must use each word a total of six times in order to complete the puzzle correctly.

Practicing vocabulary and spelling activities in different ways helps students remember words more accurately, which makes them better spellers, writers, and readers. Puzzles and brain teasers can be a fun way for them to practice.

Crosswords and word searches are always fun, but there are other types of puzzles students can try, too. Sudoku-style puzzles where students fill in spelling or vocabulary words into the boxes instead of numbers can be a refreshing way to practice. Cryptograms allow students to uncover a secret message while practicing spelling and vocabulary skills, while word ladders and word association games can help students identify synonyms and antonyms.
