I've been a stay at home mom for over a year now, and I've decided to dust off some of the teaching materials that I have created and post them on Teachers Pay Teachers. My first math activity is free and it is called Patterns in Sierpinski's Triangle. I originally used this activity with 6th and 7th graders, but it would also be appropriate to use when introducing sequences in high school.
This is currently a FREE resource and you can download it at Teachers Pay Teachers. I'll be adding a bunch more resources in my store called: "Help for Learning Math."
