I am a HUGE advocate for teaching students how to use a graphing calculator to check their answers. In fact, it’s probably one of the MOST important skills I’ve taught my students. Yes, I know…being able to find a solution algebraically is extremely important, and of course, I teach them that. And, of course, I require them to show their work. BUT, when they turn in an assessment, I want them to be confident that their answers are correct. Feedback is extremely helpful, and by using the graphing calculator it can be instant! You know, I probably should have titled this post “The Lost Art of Checking Your Answers”. Sometimes I simply don’t understand why students don’t check their answers?!?! I know that some students are just too “lazy” to check, algebraically. Yes, I said it! BUT, at they could at least use their calculator to confirm or disaffirm their answer. Just think, if students were able to check every problem BEFORE they turn in their work? Then, they would know immediately if they have an answer right or wrong…and if wrong, they can fix it! There are soooooo many math topics that students can use the calculator to check their answers. Here are just a few ways:
Do you want to make it easier for your students to navigate the TI84 graphing calculator? Watch my video that covers some tips and tricks you may not know about the TI84. You will also learn some great ways for students to check their algebraic answers using the calculator, as well as unique ways to graph. After all, calculators are only as smart as their user!
