How I Use It
I teach technology classes to Kindergarteners. Each class is one hour long. I wold have the students go to Teach your Monster to Read for 1/2 hour. I did try an hour and it was to long for them. I also used this website for a group of 1st graders that needed additional help with phonics.
I loved Teach your Monster to Read just as much as my students did! It has a tracking tool, that will let you see how the students are dong with specific letter sounds. You can also print out certificates to give to the students when they finish a level. The only negative thing that I would mention, is that is was easy for students to guess a word.
