Native American Beadwork and Geometry

1. The beauty of Native American beadwork is well-known.
2. We will be using the Cartesian coordinate system during this lesson.
3. Many Native American designs are based on four-fold symmetry, when something is symmetrical on the top and bottom and the left and right.
4. Each image could be placed on a coordinate plane and each quadrant would be the same.
5. The first image is a piece of Plains Indians embroidery.  The second image is a piece of Shoshone beadwork.  The third image is of a Pawnee buffalo hide drum.  The fourth image is a Navajo rug.
6. Reflection symmetry is when something is the same on both sides.
7. Base four counting was very common.  For instance, teepees were often built with four support poles, one in each direction.
8. Four-fold symmetry is used in Navajo sand painting, which is used for healing by the balance of forces.
9. The Yupik make parkas which use a coordinate system to remain symmetrical.
10. Four-fold symmetry is used in beadwork, which is laid out with threads running horizontally and vertically like a coordinate plane.
11. Native American beadwork was created long before Europeans came to America.
12. Wampum beadwork was used to record messages and historic events.

Communication Through Social Media

Last night, our class kept a log of all of the times we generated data through the use of technology throughout the day.  I don't communicate through technology very much.  I don't text often and only use Snapchat occasionally, and I don't post to social media sites.  I have friends, however, who text almost constantly, are often on Snapchat, and have very active Facebook, Twitter, and Instagram feeds.  There are many ways to use social media and the internet, and these are just a few of them.

About Me

Hi everyone, Morgan here! This blog is for my class in Computer Applications this semester.  I am a sophomore in high school this year.  I am in two different choruses at school, I take horse back riding lessons and I hope to be joining the Ukulele Club at school.  I love reading, writing, drawing, and making music - and listening to it too.  I love 70s rock.  I play the piano and ukulele and sing.  I live with my mom, dad, little twin brothers, a cat, and a dog.  I love Singin' in the Rain, Spirit, the Lord of the Rings movies, Marvel movies, and Disney movies in general.  My favourite shows are BBC's Sherlock, Supernatural, Doctor Who, and The Big Bang Theory.  I love to read as well.  I have read the Harry Potter series more times than I can count (only the British versions), but I also love the Percy Jackson series and Charles Dickens especially.  I would like to go to a good school of psychology and become an animal trainer, or go to an art school.

Computer Buying Project: Group Work

We're working in a group on a project in class.  We're getting a lot done, and I think that this project is going to go well!
