Cardboard Fort Engineering

About 90 minutes, indoors, for ages 5 to 7.

Where it works

Works in any indoor space

Who it's for

ages 5 to 7

Build These In:

  • box structure
  • tape joints
  • a door that opens
  • a window to look out of
  • a roof that holds itself up
  • a room only one person fits in

Today's Challenge

  1. 1.How did you reinforce the walls?
  2. 2.What is our fort’s designated purpose?
  3. 3.How do you expand the structure?

Quick Start: What you need

  • 1cardboard boxes
  • 2masking tape
  • 3markers

The Goal

Engineer a resilient fort or spaceship using spare boxes and tape with this screen-free indoor activity.

How to start

  1. 1

    Gather what you need: cardboard boxes, masking tape and markers. Nothing else required.

  2. 2

    Head indoors and build: box structure, tape joints, a door that opens, a window to look out of.

  3. 3

    Talk about what you made. Start with "How did you reinforce the walls?"

  4. 4

    Print the worksheet to plan it out and keep what you make.

Draw Your Blueprint

Before you start building, sketch your fort's layout below, doors, windows, and all.

Architects draw a blueprint first so mistakes get caught on paper, not in the actual building.

If you want to push it further

  • Test the roof with a cushion before you trust it
  • Build the door last so you can get out

Print it and go

The worksheet has the checklist, the prompts, and a space to draw in. One page, ready for a bag or a glovebox.
