We school year round, 3 weeks on then one week off. We start the first week of July and finish the third week of May. We take all of June off then start again in July. So far this has worked great for us, we don’t get burned out and enjoy having time off in winter too. We tried doing a traditional schedule like PS and then just a couple subjects in the summer. My boys don’t do very well with a couple subjects. They seem to do best doing a full workload rather than a little here and there 🙂 Now that they are a little older I gave them the choice of having the summer off or a week every month and they chose the latter. 🙂
