I don't know about everyone else, but rarely do I use curriculum exactly as is - I almost always tweak it to work for us... I'm doing just that with Sonlight 300.
History - the kids are reading the two spine books, reading the teacher study guide notes, answering the questions in writing (I will grade those), reading the historical fiction and biographies w/teacher study guide notes.... and when possible having discussions with Dad. We are not doing decade summaries or projects - decided that was just not our thing. The past three years of Tapestry of Grace History have been heavy writing so it's our year to take a break and kick back a bit.
One of the things I love about homeschooling, is the flexibility. There is no principal or SOL that dictates what I must teach - I can choose what I feel is best that particular year. This is the year that James has a job every day after school plus he's taking Calculus at UAH four mornings a week. Abigail is busier than last year with theater - first Sleeping Beauty from Aug-Oct and then A Christmas Carol from Oct-Dec plus she'll hopefully be in Players and she works three afternoons a week...... So this is a great year to relax a bit on History and English.
