Ideas 1–10 — Build & Play
1. Build a Fort
Use large boxes as walls and smaller boxes as towers to create a full cardboard fort. Cut out windows, a front door, and even a secret escape hatch. Let kids decorate the outside with markers, stickers, or paint. Add blankets inside and a flashlight for the perfect hideout.
2. Put on a TV Show
Cut a large square out of the front of a box to make a pretend television screen. Kids can sit inside and host news broadcasts, cooking shows, weather reports, or game shows. Record their performance on your phone for extra laughs later.

Tape several boxes together to create rooms and levels. Kids can design bedrooms, kitchens, and living rooms using scrap paper, fabric, and small toys. Make tiny furniture from folded cardboard and let dolls move in.
4. Build a Car Ramp
