The kids have been constructing things recently, using various toys and boxes. I really love just watching them play - they're learning about the world around them all the time.
We keep a box of funny little things for them to use in their construction projects - strings of beads, little plastic containers that candy comes in, anything that looks bright and useful to a 5 year old. Today their construction project utilizes beads, wooden train track pieces, plastic bubblegum containers, and cans of tomatoes and bags of rice! They've created a crazy roller coaster for their little amusement park.
What fun!
