Math books often teach just one way to solve a problem. I like to find multiple ways to solve the same problem because it makes you think about the same thing from different perspectives which can often lead to learning something new.
In the video below, I present two ways to think about solving the colliding trains problem.
If you can think about other ways to solve this problem, create a learning packet and let me know about it. I will include a link to it at the end.
Demonstrates how to solve the Colliding Trains Problem using an equation and using a graph.
NOTE: I made a mistake at 8:10 in the video. Train B will be 120 miles away from the start of train A, not 110 as I stated in the video.
Send me your learning packet links and I will paste them here
