Lesson 1: Getting Started
Teacher’s Notes
Using labelled drawings is an
important communication skill that
needs to be learnt. Emphasize to the
children that it is not important for
their drawing to look exactly like the
K’NEX or any other machine they are
investigating. It is more important
for their drawing to show how the
machine works. For example, they
should show how the moving parts
connect to each other.
Interpreting 2D drawings to construct
3D models is an important skill to be
learnt and from the outset children
should be asked to say what
movements/functions their model
will perform before they build and
investigate the actual mechanisms.
