My school is using the character program Top 20 this year, but the lessons are designed for 3rd grade and up. This is a modified version of Lesson 5 in the Top 20 curriculum that I used for my 2nd graders, but I think would work well for K-2, maybe 3 also. The Top 20 lesson title is Do you see or are you blind?. I hope this is helpful to you!
I've included a preview that has pictures of all of the slides, but TPT limits the size of the file so I had to get creative. You can message me for a more clear PDF of a preview if you'd like, but I don't check messages all that often so it might be a week or two (sorry!).
