Why read it?

1 author picked Think Triangles! as one of their favorite books. Why do they recommend it?

Because of this book, one of his first words was “triangle,” and he was saying it reliably even before circle and square, which makes me feel very accomplished as a parent!

This has nice pictures, which let him open each page and see what is behind it, revealing the image, which he enjoys. It is also a good size and easy for him to hold by himself.
