Reflection: Connection to Prior Knowledge Learning About the Orders of Operations - Section 2: Explaining the orders of operations

 

I continued my talk about order by giving the following example:

When I go to work in the morning I have to get into my car in a certain order.  

First, I have to open the door.

Third, I have to start the car.

Fourth, I have to put my foot on the brake.

Fifth, I put my car in gear.

 

It would be impossible for me to get to work without doing the steps in order.  In math, we have to solve numerical expressions in order so we can get to the correct solution.

This example is something the students can relate to and apply.  Other examples I've used: fixing a sandwich, doing the laundry, feeding their pets,
