matching eggs to pictures - good idea. Or have pre made eggs to match for toddlers learning colors.
I think it would be fun to make a huge design on the floor with all the dominoes connected (if you make them in ABC order as is shown in this blog post, it also would give passive learning about order of letters). E-Z to make, using craft foam.
Great way to teach reading - word family eggs - I changed this up a little for speech therapy. Each egg I wrote on in sharpie marker and I did initial and final sounds that they could twist the egg to create new words that started or ended with their sound. I give them these while I'm working one on one with another student
Toddler Teaching: Matching Colors
matching numbers...could adapt this for a post conference activity. Maybe match lab values with their normal ranges, endocrine disorders with their S, etc....gotta find a way to incorporate this idea for nursing school :) (I'm a grade school teacher at heart, and a nursing instructor in reality!)
