This is a subscription-based collection of leveled word association quizzes designed to expand your vocabulary through fill-in-the blank and multiple choice style questions (reading is required). Wrong answers are recycled, and new material is continually introduced. The more your knowledge "grows" the more a worm grows; a great metaphor for tracking progress and keeping things interesting. The content is specifically designed for upper elementary age children (ages 8-12). Note that the use of this app requires both registration and an auto-renewing subscription.
