My son and I have been working our way through 100EZ for a couple of weeks now. After a painful start, it's all going much, much better. He's getting the reading without much issue, in fact, it's going great. What he does NOT get is rhyming. At all. I cannot make him understand how it works, what it is, nothing. It's just not happening. Do I need to restart the program to make him get rhyming or do we just continue on? Help!
