Here is one of the ways I am using it.
the night before going to a meeting with our homeschool group I left my daughter a sign on her art table (See below). She loves this activity. This is a picture of how I left it ready for her.
This are the names of most of her friends.All she needs to do is to recognize a few begging letter sounds and she tells me if she saw that person or not that morning. If she did, she moves the post-it to the chart. Fun!
Here are the kids she saw today. Not everyone.
