Oh, boy, this entertained them for FORTY MINUTES! It was one of those times where I thought, we'll just see where this goes, but I was so shocked by how long and how diligently they worked to make the shapes.
We read Grandfather Tang. I displayed the book on my Elmo and showed them the shapes when we reached that point. They did a nice job of predicting which animals was coming up next, and of making them.
I was excited by their enthusiasm. Some kids were really confident, even some of my lowest math learners. Other students who excel in math and reading struggled with manipulating the shapes. Other kids loved to go around and help kids get things turned around.
