With the help of WordGirl and Captain Huggy Face, WordGirl Word Builder challenges children to twist and line up rings to find words up to six letters long. Parents and teachers can help kids who are learning to spell select a letter and then twist the rings to find subsequent letters that spell words. Once kids get the hang of it, it becomes addictive and a perfect travel learning toy. WordGirl and Captain Huggy Face are featured on the rings as "your choice" letters, making spelling new words easier. Letters have number values as well so kids can try and build words that score lots of points. The rings are easily removed and rearranged, creating thousands of possibilities. Like all Twisterz Toys, WordGirl Word Builder is free of batteries and electronics. It helps develop early spelling, language and math skills. Batteries not required. Ages 4 and up.
