Marbleslides is the latest activity from my team at Desmos. It’s simple. We set up some stars. You press a “launch” button and marbles drop.
But here you have collected zero stars. No success.
That’s Marbleslides and you and your students should play it this week and let us all know how it goes. If you want a preview, head to student.desmos.com LINK and type “eht8”.
If you want to set up your own class, head to the Marbleslides activities listing, choose a function family, and get a classcode of your own.
Here are some quick, below-the-fold notes about what we’re trying to do here and why we’re trying to do it.
Delight. Whenever possible we want students to experience the same sense of delight about math that all of us at Desmos feel. Students can experience that delight both in pure and applied contexts and Marbleslides is that latter experience. Seriously, try not to grin.
Purposeful Practice. Picture two students, both graphing dozens of rational functions. One finds the experience dreary and the other finds it purposeful. The difference is the wrapper around that graphing task. If the wrapper is no more purposeful than a worksheet of graphing tasks, your student may fatigue after the first few graphs. In our Marbleslides classroom tests, we watched students transform the same function dozens of times – stretching it, shrinking it, nudging it up, down, left, and right by tiny amounts. That’s the Marbleslides wrapper. Students have a goal. Their pursuit of that goal will put you in a position to have some interesting conversations about these functions and their transformations.
BTW. Here’s the announcement post on the Desblog.
