There are SO many great ways to use iPads in the classroom. However, it can be a little overwhelming! Last year was my first year using iPads in math class. I tried a lot and learned a lot along the way. One big lesson I learned is that there are many math "games" out there that aren't much more than digital flashcards. In addition, many are timed which I think adds a lot of stress and not much in the way of getting students to think mathematically. Read Tracy Zager's criteria for fact-based apps.
If you are new to iPads, or just looking for some new apps, wanted to share some of my favorites. Many of the best apps I found are free!
First, if you teach middle school or high school, you NEED Desmos. Download it now and read more about Sara's love of Desmos. Although the activities aren't through the app, also take some time to check out the activities at teacher.desmos.com.
ClassKick. You create assignments, kids work, you see their work while they are working, you give feedback in real time. Probably the most used app in my classroom!
Recap. You pose a question and students can quickly make a short video. Great to use as an exit slip!
Math Learning Center" are pretty good. Check out "Number Line," "Number Pieces," and "Pattern Shapes." "Solve Me Mobiles" is maybe more puzzle, but it's an awesome way for students to reason visually algebraic problems. The interactive "Geoboard" is awesome and no need to buy rubber bands (or have to watch rubber bands go flying across the room!). I used "Virtual Manipulatives" a LOT with my 6th graders last year because it has interactive fraction bars, perfect for all the fraction standards in 6th grade. While I didn't use "Think 3D Free" and "Undecided" much, I think they are worth a look. "CountingBoard" is an interactive 100's chart, perfect for looking for patterns.
Finally, I love downloading puzzle type games because they are fun but also encourage spatial reasoning, problem solving, or critical thinking. Check out Folt, Cargo-Bot, Sumaze!, and CrossFingers.
If you use other apps that you love, be sure to let me know in the comments!
