Here are 2 I Have Who Has games perfect for reviewing letters with your little ones. One game features lowercase letters and the other features uppercase letters.
Both feature adorable, cute monsters!
Printing instructions are included in the zip file. Since these were made one to a slide in PowerPoint, you have options in printing when you open the PDF.
I like to time my students when we do I Have...Who Has? games. We keep track of our time and try to beat it every time we play.
