All you need are poms poms and a muffin tray for this activity. Once your toddler master this sorting skill, there're just so many variations you can do with a colour sorting activity!
Took me couple of times to do this with Sticky Bean before she finally understands that she is supposed to sort the poms poms in accordance to their colours.
Age attempted: 20 months
