Fun book about shapes that helps your child draw

I recently bought "Shapes that Roll", by Karen Nagel. What really made it stand out for me was that it's a colorful book about shapes that comes with tracing paper tucked between each page so your kids can try to trace and color.

My son isn't quite ready to draw shapes, but I've noticed a huge difference in his coloring since he's been doing it in the book. He tries to imitate what he sees on the page.

Plus, the pages are glossy so if they're using a magic marker and they make a mistake and draw in the book, it will wipe off.
