This colorful set of three-letter and four-letter puzzle cards provides children with an introduction to spelling. They can learn to spell by associating the object with the word and correctly assembling the puzzle pieces. Each set is self-correcting, meaning only cards with the correct sequence will fit together, making it easy for young learners to assemble words in the right order. Includes: 10 three-piece word puzzles and 5 four-piece word puzzles, for ages 3 and up.
