One small change, one big impact! I'm not saying we should be wishy-washy or give in to every sign of discontent in our children, but we do need to give it careful thought and see what we can do.
Don't be afraid to adjust curriculum as needed. It is not a sign that you "failed" in picking something out the first time, but of sensitivity to your child in being willing to change! It gives your child the message that you care.
Oh, what happened to the two Earth Science books I had bought? I brought them in to sell back to the used bookstore, and oddly enough, the on-line resale price had shot up to $60 each. The store pays about 50% of expected sales price if you choose to take store credit, so I came out with $30 in credit for each $6 I had spent! Sweet deal!
