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: holds one sock against another as if comparing.
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: sort only two very different socks at a time: one grown-up sock and one of your child's.
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: puts a little sock on the little pile after one example.
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: ask 'Is this big or little?' before your child places each sock and wait for a look or word.
Change only that one thing and keep everything else the same.
Ready for one step up
Ask 'Is this big or little?' before your child places each sock and wait for a look or word. Or carry it somewhere new: sort big and little shoes by the front door.
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: sort only two very different socks at a time: one grown-up sock and one of your child's.
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: 5 minutes is plenty.
They can do it, but it was not fun today. Add difficulty only once it feels easy and enjoyable again.
