Here is a blooket version of an Alphabet matching game. I pulled the digital flash cards from the 5th and 6th grade textbook for Here We Go to make the games more clear and easier to answer. The answers are flash cards they are familiar with and it’s convenient as most students have a higher chance of recognizing the pictures than a typed answer that’s usually in a very small font. It has worked well with my students from 4th grade to 6th grade.
I would not recommend trying this with your 3rd graders as they aren’t yet familiar with lowercase letters, but if your class is more advanced, feel free to use it as well. It’s a great warm-up activity and review game, and I find myself reverting back to it quite often when there is time left over.
