Download this girder template and print onto card.

A Truss Building Exercise. Explore the strongest shape. Build a bridge or tower from trusses. Print the girders onto card, cut them out using the bolder lines, and fold them down the lighter line before construction.

• Create an M out of 4 short beams. Note which way around they go.

• 2 beams fit together to create a square corner, called a right-angle.

• Add a long beam across the bottom of the M.

• Repeat this to make 4 of these.

• Fix all 4 sections together to create a tower or a bridge structure.

• Where else might you add beams to make the structure rigid?
