So I had some pictures my mom sent me laying on my desk for the past couple months, just waiting to be used in some way, and I finally did something with them this week!
Using something I remembered from my teaching days, I whipped up a little something for the boys. I used quart size baggies taped together on the front and back to create a large photo display. When I taught, I had a much bigger display made out of gallon size baggies that was used for displaying kids' work. What I love about this is that I can switch out the pictures very easily by sliding them in the back where all the baggies are kept open. I put it at the boys' height level so they can look at the pictures any time without my help.
As soon as I stuck that baby up on the wall, Parker ran over to it and started pointing to things/people. Success!
