Calendar for kids

I found this great idea about how to make a calendar for a preschooler. Kristen made a one week laminated calendar and then she tapes pictures of each of the activities to the right place in the week: pictures of school, pictures of the sister at dance lessons, pictures of visitors, etc:  Homemade ‘calendar’ helps preschoolers understand their weekly routines: Parent Hacks.  I tried to do this for our six year old a couple of years ago because he has two homes and constantly asks questions like, "how many days am I here?"  I wasn’t very successful though as I never came up with a good way to distinguish between days at Dad’s house and days at Mom’s house – I think the pictures would have made a big difference.
