In your notebook draw diagrams of the structures

Using the development plan of an arch stone on the
right, build an arch using five pieces. Put it together
horizontally on a piece of cardboard. Raise it carefully
and check that it stays up by itself without any glue.
When making the keystones it is necessary to make sure that
the sides which support each other are flat. You can also build
a cardboard centring and place the pieces over it. In the end,
take it away and put the keystone in place.
