Green Eggs and Ham, of course!
I originally got the idea for this activity while watching Jeopardy. One of the categories featured initials of Dr. Seuss books and the contestants had to come up with the titles. Naturally, I decided it would make a great activity for Dr. Seuss’s Birthday/Read Across America.
This activity is ready-to-use (and free). An answer key is included, of course. You can download it from google drive here. I think this would be fun to do in partners or as homework (no internet allowed!). For younger students, you may want to give them a list of Dr. Seuss books or maybe just make sure you have all of them in your class library. Please feel free to share this activity with your colleagues.
