Nikolas uses LifePacs from Alpha Omega Publishing for second grade. I don't have him do a set amount of pages per day or week. I look at the pages and plan it out by they day, some days are heavier in language arts, some in history... But it is usually about the same amount of time it takes every other day. When he finished a LifePac and does well on the test, I let him skip that subject the next day.
This is the way I was doing it and it was working out really well. I just wrote out each day's work on a sticky note and he'd cross it off when he finished it. This was a 4-day week. I just wrote the page numbers next to the subject, easy. I kept these in his notebook where his handwriting practice also is.
The book is a super cheapy composition notebook, that I already had. So there was zero investment. LOVE IT.
