Review: Loves Pi so got book on Pi
Review: Happy Pi Day to You is a great read, covering the basics of Pi. A few pages in, the theory gets a bit advanced for young readers but they will learn and advance with this book. A wonderful book to enlighten minds on a difficult topic for kids.

We’ve read this so many times at my house! My 4 yo was encouraged to ask so many follow up questions. Great book about math and how it can be found in our day to day lives and history. Also included great project ideas!
