Children will love using the Design & Drill Activity Center to create their own designs, or follow the set’s colorful activity cards to make pictures and patterns- from trains and boats to flowers and fish. Just snap any one of the drill bits into the reversible power drill or the screwdriver handle, grab a handful of big bolts, and turn on the learning fun. Twenty colorful activity cards (10 make-a-picture cards, 9 follow-the-pattern cards and 1 make-your own card) provide young learners with tasks from simple to challenging. Complete set includes one reproducible blank grid for make-your-own card fun.
