Recently, our daughter started asking to add more activities to the schedule. We're going to wait until after school starts, to see how well she does with the next level of academics. I've heard from several parents that they noticed third grade was considerably more difficult than previous grades, and I want to make sure our daughter continues to do well in her studies before adding more fun stuff after school. I'm currently reading this parent's guide to third grade to prepare, which you may also like to review: http://www.education.com/grade/third-grade/
I hope more parents join this discussion and share their thoughts about the right volume of activities. Thanks for asking!
