Well a good learning website is Its for reading of all ages, and they have fun interactive abc learning
If you type in teaching two year olds in the search bar, I’m sure you’ll find MANY sites that have some good information. For the most part I think anything you do with them should involve being active and experience with different media.
I love the website
The Complete Resource Book for Toddlers and Twos by Pam Schiller.
Actually Pam Schiller has many toddler books published…check your local library.
Back to the book I mentioned- It is a good resource book…but use it as a jumping board. Be careful with those books that have lesson plans all ready for you. It may not be what your classroom/children need. You need to individualize…make it personal for your classroom.
Just a side note…are they coloring in coloring pages? Or are they coloring in general on many many different textured papers, with many many different writing tools? Coloring pages are not developmentally appropiate for 2 year olds.
