Parent tip

Set out blankets and cardboard boxes before inviting your toddler in so the first minute feels smooth.

What success looks like

Intense focus, even briefly. Watch for the small ‘aha’ moment when they figure out how something works.

Open-ended construction play that fuels imagination and spatial reasoning. Figuring out how boxes fit together, which ones can stack, and how to create an enclosed space develops early engineering thinking and problem-solving skills. Once the fort is built, it becomes a launchpad for hours of pretend play as children transform it into a house, cave, spaceship, or shop.

Why it helps

Figuring out how boxes fit together develops spatial reasoning and early engineering thinking. The pretend play that follows builds language, creativity, and social skills as children invent scenarios and characters for their fort world. The EYFS framework identifies imaginative play as essential for developing language, empathy, and the ability to see things from someone else's point of view.

Variations

  • Cut windows and a letterbox for posting 'letters' through.
  • Decorate the outside with paint or crayons to make a shopfront or spaceship control panel.
  • Connect multiple boxes with openings to create a tunnel system.

Safety tips

  • Remove all staples, tape residue, and sharp cardboard edges before play.
  • Ensure the structure is stable and will not collapse onto your child.
  • Supervise closely if using scissors to cut openings.
