Mathematical Art: DIY Fibonacci Spiral and My Big News

I have BIG NEWS!! My life is changing. After leaving teaching high school math sixteen years ago to get married and focus on family, I am going back to the classroom full time in the fall. Then on top of that news I have been helping out four days a week in the school's directed learning center since someone left at the end of April. My life has been a bit different, and you can tell by the number of posts I have been doing. This will mean some changes to Crafty Moms Share, but I am not sure the extent yet. I will change my focus to more math-based posts but am hoping to still review some books, especially math focused ones and young adult ones so I can connect with my students. I will also be doing more origami, so be ready for review of origami products.

Math Lessons: Math in Nature

Today I am sharing some books to combine math with nature. Now as a math teacher I know the importance of seeing math everywhere. It allows the student to really see why mathematics was invented. People needed to understand the world around them and mathematics helped them do this.

Fun & Useful Math Books for Different Ages

Disclosure: I was sent these books in exchange for an honest review. All opinions are my own.

Today we get to talk about one of my favorite subjects! MATH!! As a former high school math teacher, I always love talking math. My life has been a bit busier because I have been volunteering and subbing at the high school end of Hazel's school. My volunteer work is helping kids with their math and sometimes even being in the classroom as an extra adult to help. I love it! It feels good to be back in the classroom and especially without all the grading and politics! Today I am going to share four books that involve math, and they range for ages 7 through adult. We will start with the origami book. Origami is a fun activity to bring into the math classroom and there are so many math applications involved. The book There's Math in My Origami! 35 Fun Projects for Hands-On Math Learning by Fumiaki Shingu, shows how math can be taught in the origami projects. It is recommended for ages 7+.

Pythagorean Theorem Fun -- DIY Mathematical Art

As I continue to think about my new job in September and plan for what I want to hang in my classroom, I am exploring the Pythagorean Theorem. The Pythagorean Theorem is probably one of the most well-known or well-remembered theorem in math. It is often taught in both algebra and geometry. In algebra it lends to working with exponents and roots and in geometry with triangles. I have seen memes saying how people did not use the Pythagorean theorem today, but I have also been told by many people that they have used it in their lives from building a new deck and woodwork to programming and more. Although math has real life applications and was mostly discovered to explain the world, much of math is taught to help develop the brain of our children. In high school the brain is just beginning to truly develop its logic skills and math is huge in helping with this. The Pythagorean theorem also is mentioned (incorrectly) in the Wizard of Oz. Yes, it is this famous!

Although it is named for the Greek mathematician, Pythagoras, it was known throughout the world before his time. It is referenced in Ancient Egypt and Babylon (around 1900 BC). Apparently, it did not become as well known until Pythagoras stated it. There are many proofs of this theorem and some of them like the one below is a visual proof.
