If you find it hard to fit in schooling in the traditional hours, here are a few suggestions:
Consider some schooling in the evening. I don’t make a habit of this, but when we haven’t really gotten much accomplished in the day time in the way of schooling, some times we pull out the books at night. We usually don’t go much past eight or so, though. My oldest son seems to do better studying at night on his own.
School at Meal Time
More untraditional, but more and more frequently, I am finding that this is an excellent time to get some schooling in. Classes like Islamic Studies or Home Ec classes (traditional non core subjects). I wouldn’t try math or science. However, I do make up review sheets for various subjects (including subjects like math) and on occasion, whip them out at meal time (breakfast and dinner are better for us) and quiz them.
This morning we had a home ec class on biscuits (I made them for breakfast). I did the making, but I found a great fact sheet on biscuits and so sat down and read it to them while they ate and then quizzed them.
Another benefit is that you might be more inclined to gather everyone together for dinner if you don’t traditionally do so.
Sometimes I just pick something off the cuff and go around the table and ask each child a question based upon his/her level, though it could be the same subject for all kids.
In addition, this is a great time to hold an eating etiquette class/review workshop.
If the kids are bored during the weekend, do a little light school. We used to only take off one day (Jumuah/Friday) for school, but to give the kids more motivation and me more time to prepare, we have a two day weekend (Friday and Saturday). But when the kids get bored, a little light school or review could be done. After all, in public school, we did have homework over the weekend.
