Yup – I have to agree. Plan on doing math each day for your scheduling, and don’t plan how far you are going to get in any course.
I use MEP which has about 175 lessons aprox in a year. Sounded not too bad for 160 days of school, plus a bit more in the summer, or skipping some of the review pages…. But I learned pretty quick that some of the lessons needed to be broken into 2. My son also had problems with a VERY basic concept needed in MEP (Less than and More than) that I had to do a couple of things on our own. And some interruptions came into our school (sickness in family etc)….
I have come to the conclusion that math will come at the speed it comes. I aim to do a MEP lesson each day, but if it doesn’t happen, it doesn’t happen. Wherever we end up at the end of the year will be fine, and we will do some during summer too. (and I won’t have to go looking for review material in the summer!)
