The Activity Board will keep your little ones focused and engaged for a LONG time! Perfect for tinkerers that want a challenge or kids who enjoy creative and critical thinking activities. We designed the Activity Board to give our oldest child an avenue to explore and create patterns while developing fine motor and decision making skills. The Activity Board features an engraved rainbow design with round holes and a set of multi-colored wooden balls that can be positioned in any order or pattern than you can think up! You can follow a classic pattern or mix and match the colors to create your own designs! Just for reference, we included a LOT of wooden balls for the Activity Board.
