This is what I have learned. Don't start with the subject that everyone loves the most (if there is one). Start with the subject that everyone dreads (including you). You need something to look forward to. Also, if you start with the favorite, by the time you get to the worst, everyone is tired and unmotivated.
Around here, Math seems to be the worst for my 2nd born. She struggles big time with the concepts and remembering what we learned last week, yesterday or even 10 minutes ago.
The days that we leave Math for last are complete torture! By then, I have lost all attention span and focus. This would explain the aggravation from my previous post.
