SpellQuizzer is $29.95 per computer. There is a little bit of work and time needed to set up the recordings of the spelling words and hints. The spelling list can be saved in the program for use with multiple students. Great for homes with students studying at different levels.
We did not get to use this program much because we were in the process of moving, but I liked it. My child loves the opportunity to learn from someone besides me. My 4 year old stood over her shoulder to watch the learning take place and learned a few things on his own.
