Always nice to have this moments. I'd often wondered how moodle techniques could be used to improve skills in numerical problem solving.
In a session on Physics (AS Level, 16-17), I showed my students a standard format for solving the 'suvat' equations of motion.
One student turned it into this handy template and posted it on a moodle forum. Use it to write what is known, working and tick off a checklist. Hope others may find it useful.
