Building is a fun game even for the smallest tikes. They help a child develop spatial and abstract skills, mathematics, and some basic geometry. They are good for both working individually and for developing teamwork skills. Plus, building sets and toys are no fail toys to entertain on a rainy day. Certainly as a child gets older, more advanced kits can make for a good excuse to schedule some parent and child bonding time. Here you will see some examples of blocks, building kits, and models to serve as gift ideas. The items on the left are for a younger audience and advance to suit older kids on the right side. Always remember to check the age requirement on a given product. Small parts can be a choking hazard to toddlers, and projects that are too basic will bore an older kid.
