As you know, your online task time will often dwarf the actual brick and mortar requirements of traditional schooling. Yet, even though our children spend less time on a computer terminal, actual content and lesson absorption can be much greater due to the interactive ability of online learning.
With a bit of this extra time, I encourage you to to put together an art box full of crafts and projects to encourage the sheer sense of creativity in your child. Some students may just want to free draw to relieve stress. Others may require actual projects and directions as that art bug has just not been tapped yet.
I do encourage you to use Discount School Supplies Arts and Crafts. There are several sections of creative play that will tap into any learner. Set time aside each day, or several times a week, for an "actual art class" as you being the instructor. After all, you are your child's academic learning coach! This time will be rewarding for you and your child as you will make some positive, delightfully divine projects to bless your house.
