Sometimes school is boring. I know because I volunteer in my homies' classes, and I nearly die of boredom every time I'm there. I think the fear of performing poorly on standardized tests has forced schools to adopt curriculum that will ensure testing success. This drill-like and repetitious way of teaching is tedious and dull, to say the least.
That's why I'm understanding when my kids complain, "I don't want to go to school today. It's so hard to listen for that long." I tell them, "I feel your pain. I could hardly sit through grading papers without grabbing the bathroom pass for a little powder room break. But your job is to do your best, no matter what. Look forward to the good parts of school--library, recess, lunch, art, music, and coming home to your dear, sweet madre." (The sweet part happens five times out of ten.) They usually agree to do this and move on.
But sometimes they really dread going, and their complaints become endless. That's when I cut them off and say, "When I pick you up from school, there will be a treat on the seat, waiting just for you."
This small incentive (bribe) makes them move past the dread and helps them to focus on the positive parts of the day. It also gets them off my back, and I think that's why I really give them the treats.
