Children can form more than a thousand words using this toy. They love spinning the bright wheels and moving the desired letters in the frames while building their vocabulary. The toy comes with a word booklet that helps children identify, form and spell words in the initially stages. As they continue playing with the toy, they start forming words independently. The toy is extremely handy since it does not have any loose parts and keeps children engaged for a very long time thereby improving their knowledge of language tremendously.
