Math Tutor: Order of Operations PEMDAS (BODMAS and BEDMAS)

Ranked #108,861 in Education, #1,635,133 overall

The Order Matters

When you make spaghetti there are certain things that have to be done first. You definitely want to boil the noodles before adding the sauce. Otherwise the result would be disastrous!

The same is true for simplifying math problems. There is an order that needs to be followed so that we all get the same answer. If you don't follow the order of operations, then you basically get crunchy spaghetti.

Information Age Teacher Resources

Welcome to the Information Age. Our kids are digital natives and we, as their teachers, need to provide a safe road map for them. I've created some resources to support us in entering the digital age.
Educating Millennials
Millennials are the New Generation. They are born in the Information Age. Check out this lens and learn some great strategies to support your Millennial students.

Ideas for Teachers

We all use technology everyday. However, it often stops at the classroom door. Here are some helpful sites to joyfully launch you into the Digital Age in your classroom teaching.
  • Homework Assignment: I gave visiting this lens as a homework assignment for my kids. I made them write a few sentences about what they did and learned. I gave the students a few days to get the assignment done to accommodate for possible computer issues from home.
  • Lab time: Take you class into a computer lab to do a webquest on order of operations. Have a list of several sites to go to. If you want them to see the videos, you may want to check if the YouTube video site is blocked.
  • Share this lens with others. I have a link to it on my website. Plus, I've shared it with colleagues... and you!
  • YouTube.com: This is a free website where you can watch videos or post your own videos. If you like the videos I created you can subscribe to my videos. You need to have a YouTube account. I've also created a group called "Math Tutor," which has videos from other people too. If you join the "Math Tutor" group you can post videos as well. It is my intention to have numerous teachers and students make fabulous videos that all of our kids can benefit from.
