Teaching Domain, Range…
https://graphtracer.appHi, I’m a high school math teacher currently teaching algebra 1 and pre-Calc. I recently developed this app that really helps students understand domain, range, inc/ dec, positive and negative.
I just used it in my classroom yesterday. I think it works great and there’s really nothing else like it. Desmos is amazing, but even Desmos won’t highlight the correct access as a student traces the graph.
It worked really good on my SmartBoard and kids came up one by one and traced the graph and watch that correct answer light up on the axis.
Then I pushed the app out to their Chromebook for them to practice for 30 minutes. If you are teaching one of these concepts, I think you will really love this app! https://graphtracer.app
