Are there any commercial programs available like Blend Phonics?
Yes, there are several. I have taught a number of them. The main difference is simply that Blend Phonics is free. It also has the advantage of being very easy to teach. The purpose of this web site is to promote Blend Phonics only. You can find other programs on the Educational Page my web site www.donpotter.net . That web site is very comprehensive. This Blend Phonics web site is purposely kept very clean and lean. I do not want to confuse people with a plethora of options.
