Other times they use a dynamic medium only to evaluate students, to tell them that their ideas are right or wrong. Sometimes they offer the same paper material only in a digital worksheet or in digital presentation slides. Desmosification #2: We connect the concrete and abstract representations.Īll too often, computer-based math-even other computer-based adaptations of Illustrative Mathematics-fails to take advantage of what makes computers special. This invites more learners to the mathematics. With the digital medium, we’re able to ask students questions about the graph without numbers first, questions like, What do you notice and wonder here? and then later introduce numerical precision. You need to put math in all of its forms on the same page. Math curricula often move students quickly to numerical precision before students have had a chance to experience mathematics in a more concrete, intuitive form first. Here is how the lesson starts in the paper Illustrative Mathematics materials. Our lesson “Robots” ( use it for free!) is based on IM’s lesson “ What a Point in a Scatter Plot Means.” Here’s what that means.ĭesmosification #1: We use “progressive disclosure” to give students concrete experiences in math before abstract ones. So, periodically, we’re going to give you folks a look inside our digital mathematics playbook. We’re very proud of those results and want to share some of the labor and love we think they represent. Here is how those teachers responded to the same Net Promoter Score question. So we built a Desmosified version of an Illustrative Mathematics unit, and later, all of Grade 8. We get to decide on the best medium for whatever mathematics we’d like to help students learn. Meanwhile, at Desmos, we work with paper and computers. It includes a few digital applets, but they’re supplementary, not core to the student experience. Illustrative Mathematics was the only curriculum in our sample with a positive NPS.īut Illustrative Mathematics was built for paper. Positive means more promoters than detractors. We then asked 68 teachers how they liked their current curriculum using a tool called a Net Promoter Score, and Illustrative Mathematics was the clear winner.Ī negative NPS means more detractors than promoters. We loved the coherence of their curriculum, the way they told middle school mathematics like a story. At the same time, Illustrative Mathematics and Open Up Resources released their openly-licensed core middle school math curriculum. Several years ago, we realized that in order to have any kind of meaningful impact on a student’s math education, we needed to integrate ourselves into their daily math experience, especially their curriculum.
