I know Matthew started reading when he was 2, simple words you know...Matthew was 4 when he started 1st grade and really, we coulda skipped 1st grade, it was so easy for him. But I didn't want to. I wanted it to be easy for him and get him off to a confident start. We used Calvert School that year.
Joshua is six and right at where Matthew was when he was three. Joshua is blessedly right on track! Everything came (and still comes) easy for Matthew...with Joshua I think I'm more delighted with his learning because he really works at it and success means so much.
Joshua is also extremely motivated. When he gets up, he wants to get started with school and get it over with. He'll be actually done with his classes for today in about 20 minutes!
Matthew requires a lot of prodding!
All of us learned at different times - I think that was really one of the beautiful things about homeschooling, though I wasn't homeschooled when I was first learning to read. One brother (who would probably test in the genius IQ range, seriesly!) didn't learn to read even simple stuff until he was over seven. Mom tried and tried and it just didn't click for him. Then it came suddenly. On the other hand, he was INCREDIBLY good with math and music. Still is.
Margaret read at three - she was the earliest. She's almost scary bright in some ways... I learned a little early - maybe at four or so - mostly because I was sooo eager to read books. Most of the others fell somewhere in between.
