Speaking of talented colleagues, check out the Kolam Tiles Christopher Danielson is now offering in his Talking Math With Your Kids store. I’m very lucky to work with so many people who operate at the extreme end of the talent, intelligence, and character scales. BTWįawn Nguyen and Lauren Baucom have joined Amplify. What I'm suggesting is that what students gain when they know they’re right and wrong is often exceeded by what they lose in opportunities to learn about mathematics and about themselves as mathematicians. And that feedback is often evaluative –immediately telling students they are right or wrong. But computers are only good at providing certain kinds of feedback and only on certain kinds of thinking. No one ever got thrown out of an edtech party for talking about how great computers are at providing immediate feedback. So we don’t tell them whether or not their card is correct. Let’s get real confident about it.” If students know their card is correct, they’ll be less inclined to scrutinize their reasoning. “This card is the one that is in the wrong group most often. This winds up being a powerful conversation starter! The Desmos platform collects all the card sorts in the class and lets you know which card is incorrectly grouped most often. Here is a feature that I have learned no one knows exists. But I would like to offer what I see are the opportunity costs of letting students know they’re correct. I’m not here to judge anyone’s pragmatism. Speaking pragmatically, it’s hard to have students sitting around, feeling like they’re done with a task, feeling like they don’t have options for feedback or follow-up. They have frequently taken matters into their own hands, either by projecting the teacher dashboard in front of the class or by adding a custom-designed screen to the activity, giving students access to that same information. Teachers have occasionally felt antagonized by that choice. Desmos lets the teacher know whether or not the student is correct via the teacher dashboard.īut Desmos doesn’t tell students whether or not they’re correct. Using a word wall or a word list to remind students about the expected terms will help students as they work through the sort.For example, I taught this Desmos card sort in seventh grade recently in Oakland, CA.Ĭard sorts are interesting because the Desmos platform knows whether or not the student is correct-whether the right algebra card is matched with the right graph card and the right story card. I love listening in on their conversations.Ģ) Scaffolding vocabulary: As students work, encourage them to use good math vocabulary. ![]() Here is the link to the paper sort.Ĭonsiderations as you plan to use this sort:ġ) Grouping: I've found that card sorts work best when students work as partners. Then in grade 10, it could be used as a review activity before introducing rational functions. In grade 9, the sort could be used as part of a study of the attributes of linear and quadratic functions. In grade 8, you can use it to establish the concept of constant rate of change. This card sort fits well in Grade 8, 9, and 10. It's done and available on Desmos Activity Builder. ![]() Recently +Desmos asked if they could create a digital card sort using this set of functions. I've written about card sorts in the past, and specifically highlighted the sort on Linear or NonLinear Functions. ![]()
