![]() ![]() Teachers can also display all the solutions, with or without student names, and ask the class to analyze each other’s strategies. Or, maybe each student submits the problem they devised for other students to work on. Teachers could also have students create their own glass filling at a specific rate and ask them to graph that. “Our core assumption is that students need to be aware that there are other students in the class, and that refining process is part of every math lesson,” Meyer said. Teachers can shut off this function, but Desmos intentionally made it a default to encourage discussion. When a student submits his graph, a Desmos default function then shows the student three other student answers and asks him to give feedback on the solutions. One slide might have a video of a glass filling with water, with a question asking students to graph it. In contrast, Desmos allows teachers to make a series of slides with interactive elements. Meyer argues this model doesn’t capture what’s powerful about a class full of students. “Typically, online math platforms have no concept of the student in relationship to other students,” Meyer said in reference to “personalized” programs where students work through a set of problems or concepts “at their own pace,” but do so in a vacuum. And, a math classroom at its best is also a place where students are creating hypotheses, testing their thinking, critiquing each other’s work and discussing how and why mathematical laws work. Meyer says students love the internet because it’s a social place to share and create. Led by Chief Academic Officer Dan Meyer, a former math teacher who left the classroom to pursue a PhD in math education, Desmos has been using its platform to model how technology could change pedagogy.ĭesmos tries to harness the social nature of online interactions into meaningful math inquiry. Recently, Desmos has been building out its platform to offer customizable lessons. It's really hard to use this tool in a traditional boring way.' Audrey McLaren, math teacher in Quebec, Canada 'This tool is transforming how I'm teaching stuff. That’s why some educators are excited to see Desmos - an ed-tech product best known for offering an online graphing calculator - adding features that promote inquiry. ![]() Time to use the four spinner, which can produce more complex expressions.Math instruction can be the most resistant to changes in pedagogy - even schools that have had success with project-based learning or inquiry-centered approaches can struggle to teach math in ways that help students understand the rich connections and complexity of the subject. This is a great way to slowly introduce some algebra with just two spinners, but slowly build up over The completedĬan be clicked to reveal it, followed by theĪnswer. This mode works in a way similar to the calculate mode, but an algebraic expression is shown. When the spinners have stopped aĬalculation is revealed using their values. The first spinner is letterįollowed by spin. To view the calculation in algebraic notation clickĪlgebraic expression. You can see the way the computer calculated the result by clicking theĮxpression above the target number. Note the number is always attainable and obviously there might be more than one way to get the result. The aim of the game is to use the operators Ã,+,- to reach the number When the spinners have stopped you will see a The rule guess game is not too dissimilar to the countdown game shown on British TV. ![]() ![]() There is also an option to not allow negative numbers occuring in the The game modes use the spinner values, this means that they really require at least two spinners and the challenges are In this mode the controls to change the number of sides on each spinner are visible. For example to generate random numbers, or probabilityĮxperiments. In edit mode, you can use the probability spinner however you want. The slider max value is 12, but if you click on the number you can enter your own manually, although in practiceĥ0 is about the maximum number that visually fit on the spinner. To change the number of sides for the spinners make sure you have selected Initially six sided hexagon spinners are shown which are useful Number selector in the top right hand corner. You can change the number of spinners shown by clicking the Produce a result using addition, subtraction, multiplication and division. With the built in activities you can practice BODMAS, algebraic substitution or challenge students to find the rule to These can be used as random number generators The spinner activity can display up to four spinners. ![]()
