I love teaching in a co-op with other homeschoolers and former public educators. We are an incredibly diverse group—racially, ability-wise and religiously. We also incorporate diversity in our guest speakers and field trips. The first day of school this year, we were chanting and doing art projects with Tibetan monks. So how do we make Mix It Up at Lunch Day unique with this gorgeous hodgepodge of people that is already used to joining together?
