![]() ![]() This will take data from any microphone connected to your computer and display the live audio data. If you are browsing using the latest version of Google Chrome, the input dropdown box allows you to select "live input". ![]() (You can also choose to display a square wave.) The frequency of this wave can be adjusted by using the "Input Wave Frequency" slider. The initial signal above is a 200Hz sine wave, which has an amplitude of 5 volts. This allows you to measure properties of the wave, such as amplitude or frequency. oscilloscope is a useful tool for anyone working with electrical signals because it provides a visual representation of the signal's shape, or waveform. Jay Chow create this Desmos magic? I think it may have something to do with this… and boy, do I have a LOT to learn!Ĭomputation Layer, the private scripting language that powers all of our hottest activities, is now available free for anyone to use. It was REALLY SOMETHING! All I can do is encourage you to work through these awesome tasks yourself, launch them with your kiddos, and get ready for high energy, determination, and JOY!!! And… some groups just started doing the math worksheets! I didn’t let this linger long… I stopped by their groups and said, “Some groups found a code in their envelopes… did you get one too?” “NO WONDER! I WAS WONDERING WHY YOU’D PUT WORKSHEETS IN HERE THAT HAVE MATH ON THEM FROM YEARS AGO!!!” I let them know to use the back of the worksheets to do any figuring and they chuckled and got right to work!Ĭan I capture the energy in the room and convey it accurately to you here? Nope. Then, just like that, student groups got together, started typing the mysterious code into various apps, eventually trying it in with success. They found the index card with student names on them, and realized that #BREAKOUT was a huge clue about what we were about to do… □ Students with envelopes were instructed to wait until I gave the word, and they were to open them simultaneously. Yenca up to? What is this “mail” she’s giving to us? Is she going to call my name? They know me, and started grinning and hypothesizing. I called the students to the front to receive the stuffed envelopes, and the buzz was immediate. On launch day, I started class by standing at the front of the room, announcing that some students “got mail”. Thx PUMPED to use your Quadratics Breakout tomorrow! I stuffed envelopes w/ index cards containing S group member names, a mysterious code (to the activity) old 1-sided worksheets (for scrap paper… and also to make them wonder what they’re for… □) #MTBoS /r6ox1PDKKt I wrote the name of one group member on the outside of each envelope as well as #BREAKOUT. Also in each envelope was an index card with student group members’ names, and that mysterious “code”. To add a bit to the “drama” of introducing these “Escape Room” tasks, I stuffed envelopes with old, one-sided worksheets (to be used for scrap paper, not to do the worksheets… would students actually just start working on random worksheets that didn’t even align with any math we’d been learning?). I didn’t want student groups to know that they were all doing the same task… at least initially… I also didn’t TELL them what the code was for. I created student groups, and generated several Desmos activity codes so each group in each course had a different code. I decided to use the quadratic activity with my Algebra 1 students, and the linear activity with my Math 8 students. I love how Jay addresses paths in his activities for those who might make a mistake along the way, as well as the variety in the tasks themselves. Boom.įirst, I worked through his linear and quadratic escape tasks, filling pages of notebook paper with work I’d anticipate my students might do. …until RECENTLY when I learned about Jay and the way he connects the idea of “breakouts” with math content using the Desmos platform. SUPER FUN! This idea was on my never-ending “TO DO” list of things I’ve learned and would like to try with students. ![]() At several teacher workshops over the past few years, I’ve experienced “Escape Room” tasks that married the novelty of “breaking out” with academic content.
