No level picked yet. The 0–4 scale is a learning log, not a test.
Not yet: show it once, then let them explore
Watch for the first sign: makes lines, dots or round shapes with chalk.
Not yet is information, not a verdict. Do it once yourself while they watch, pause, and offer it again in a few days.
Simplify one step
Next time: skip the chalk drawing; they only brush water over the marks you made.
Give the least help that works: wait first, then point or show, and guide hands only briefly.
Repeat the same version and fade your help
As you step back, watch for: brushes water over their own marks on purpose.
Pause a few seconds longer before you model, and swap showing it for a point or a gesture.
Offer it once more, then add one change
When it is easy again: draw two colors side by side and paint where they meet to mix them.
Change only that one thing and keep everything else the same.
Ready for one step up
Draw two colors side by side and paint where they meet to mix them. Or carry it somewhere new: dip chalk in a little water and draw on dark paper indoors.
Starting it on their own or using it in a new place is the strongest sign. Still change one thing at a time.
Stop and rest this one
In 2-3 days, come back with the simpler version: skip the chalk drawing; they only brush water over the marks you made.
End with something calming together. One hard moment never means a delay.
Stop on a good note
Keep this version and keep it short next time: 10 minutes is plenty.
They can do it, but it was not fun today. Add difficulty only once it feels easy and enjoyable again.
