Here is a letter matching activity we did in the classroom last week in my 3 year-old classes. It was great for letter recognition and matching. :)
They did wonderful!-- and it was a great way to assess them, too. Another idea I had for my older kids was to match upper and lower case letters. Maybe do numbers to dots, etc. The ways you can tweak this to fit into what you need are almost endless!!! Shapes, colors (use other, non-neon, dots), tallies, sight words...... MEH!! :D use your imagination.
P.s. I did raindrops no blue paper to match our "weather" unit. You can really do whatever you want!!! :) I also made umbrellas. :) Switching it up would be a way to bring your theme into your curriculum.
