The beauty of our design is that you can start anywhere!
If you see your students are struggling with vowels, you may want to start with the Benji the Beaver Series that focuses on ea.
If they are struggling with controlled R, grab the Dirk the Bird Series that focuses on: er, ir, ur.
You get to choose where to start and where to stop based on what your class needs because we all know there is not one class alike.
