How My Daughter Learned To Read...
It allows you to explain exactly why all English words are spelled the way they are.
It provides easy-to-follow activities that make learning fun.
I can't recommend this enough.
Brain Quest Workbooks
These workbooks have given my daughter a great sense of accomplishment. She get's very excited when we complete one, and when the next one arrives in the mail.
Another great tool that makes learning fun. These cover reading, writing, spelling, math, and other basic skills.
Each book includes a series of game cards on the last few pages, that serve as a fun way to reinforce what they've learned. Highly recommended!
