RLTL will cover phonics, spelling, and reading just like you thought. It would work quite well with FLL/WWE. We used FLL in the past and currently use RLTL and ELTL.
Hi! My name is Cassie and we decided to homeschool our three kids next year. My daughter is 8 and I have two boys ages 6 and 4. I've enjoyed reading the boards so far and look forward to gaining a lot more knowledge about homeschooling.
