deiyezooger, I am an asst for 5 and 6 year olds. We gave homework over succos as a review since the girls are off for close to 3 weeks, there is definitely time for them to forget the things we learned (nekudos). The homework should take all of 5 minutes though. Even an older child can do the homework with the preschooler. Maybe this is the teachers thinking when she gave the homework because this was our thinking when we gave our homework.
Good yuntif!
