My Favorite New HW Site!

I am trying to start blogging and am taking part in the 2016 Blogging Initiative by the MTBoS.


One of my favorite websites that I actually came across a few years ago but wasn’t really able to implement well until this year is called Delta Math.

This website has continued to get better and better each year I have seen it. This year my school went 1-to-1 with Chromebooks. Every single one of my students has their own Chromebook. This has allowed me to start assigning homework online. I assign students a Delta Math assignment on a weekly basis. I assign it Monday and it is due Friday. Usually 10-15 problems or so. Delta Math is great for a number of reasons:

#1 It is FREE. That’s right: FREE! You can setup an account and get all your students accounts for FREE.

#2 Every topic you assign usually has tutorial videos as well as worked out step by step solutions so students always have a way of seeing an example.

#3 You can set up the assignments so kids are not punished for incorrect responses. I usually set mine so students have to get 5 problems right but this doesn’t have to be in order. Students can make as many mistakes as necessary until they start getting the concepts.

#4 The topics are constantly being updated and added to every few months. More “common core” friendly material and problem sets and aligned material have been appearing recently which has been great.

This site isn’t perfect. A lot of the problems are for procedural practice which is why I assign this weekly instead of nightly. Some of the concepts and walkthroughs are a little old fashioned and not what students may have discovered or found in your class. (For instance I avoided talking about the “vertical line test” but after assigning the delta math my students came back and starting using that language instead of the ideas they developed about functions in class). Also be sure to try some of the problems as I accidentally assigned some quadratic formula to my Algebra II students in the first few weeks of school only to realize that it included complex solutions (oops!).

Enjoy this website and I hope it becomes one of your favorites too!




First Post

Hello everyone! This is my first blog and first blog post ever. Let me introduce myself. My name is Jon Sturtevant. I am a high school math teacher teaching at Granada Hills Charter High School in the Los Angeles, CA. I am very excited to start this blog. I am a fourth year teacher and I am also part of Math for America Los Angeles as a teaching fellow (probably applying to be a master teacher this year). I want to start blogging for a number of reasons:

#1 To start sifting through my thoughts and have a meaningful way of reflecting. I constantly reinvent myself and try new things. I need to start documenting them/actually reflecting so I can start to improve in a more systematic and strategic way.

#2 To help share/archive some of the things I do/try throughout the year. The good, the bad, and the ugly.

#3 To start interacting with the global community of math teachers. I have been a lurker in the Math Twitter Blogosphere for a long time but I feel like it is finally time to contribute/start a conversation. #mtbos

#4 I want to be the best teacher I can be. That will only happen with constant collaboration, and trying new things. I work with a few great teachers at my school (our math department has 27 teachers!) and they help me everyday. I can only imagine what a global community of teachers like them could do.

I am very excited to be here and hope I can keep up and blog a little bit this year and see how it goes. Here goes nothing!
