This is a great independent activity for students to do to see if they can visually discriminated between uppercase and lower case letters. This could also be made to match uppercase to lowercase letters or vice versa.
As an intervention specialist, I try to create and use activities that my students can do independently when they have extra time, or when they are in their independent offices. This resource is great for that, and also gives me assessment data on letter matching.
I use this resource as a file folder activity, which is easily put together by printing the resource off on card stock paper, laminating for durability, and adding some velcro. I am working on creating a whole set of these, and as I do I will be sure to upload them. =)
Enjoy. As always, leave feedback, and let me know suggestions or things you would like to see.
