This is something I just started for my two year old who is thriving at the moment and learning everything like a little sponge! I learned a few tricks working at a day care :) you can get posters and other learning things from the dollar tree
I could change this up a bit by using a clothes pin and putting it next to the task we're on for a visual. Great for kids with autism.
Helpful for teachers with distractible students
