A box full of rrrrrrrr

My two /r/ girls have been working on these "R" boxes for a month now. The girls first filled the boxes with: /r/ and /er/ pictures, /r/ and /er/ sentences, and then conversation topics. After that, I let them go at it with all of my art supplies! Here's the finished project, aren't they about the most beautiful things you've ever seen? I'm sending them home next week so that they can practice at home!
