Incorporate Desmos Graph Calculator into assessments Note that you can also use this tool to save the image of the graph (with some exceptions) and to embed it in other platforms. The link created will send students to the graph and let each student view and modify it separately from other users and without affecting the graph you created. Share the graph(s) with your studentsĬlick on Share your graph tool located in the top-left corner. The Video Tutorials library is extensive and easily searchable and the Desmos User Guide provides the basic guide on Desmos tools. Students can learn how to create sliders and tables, define domain and range restrictions and perform regression by following simple interactive tours provided by Desmos. The Help section provides a large bank of explicit and interactive learning resources for new and experienced Desmos users. Direct students to explore tutorials on Desmos graphing tools For best progression, the tasks can be organized under folders and guided by notes from the instructor built into the Desmos graph. Note that the tasks can include static and dynamic exploration of the model, including visualization of change through the slider tool. Let learning outcomes guide your set of instructions. If using the activity as part of an assessment, ask students to import randomly generated data (from an Excel document, for example) so that there is variability in the resulting functions. State the function, function components or the data to be modelled by a functionĭesmos allows the user to state function(s) explicitly and to model data with a function using regression. (Add Item), then “ ” note, and add the description inline 1. Enter a short description of the activity: position the cursor in line 1, click on Open the Desmos Graphing Calculator and create a graphĬlick on Untitled Graph and enter a title for the graph (this is only available to registered users). However, the graphing functionality of Desmos is not restricted to account holders, in which case one can maintain access to one’s work by creating a share link and saving it for later. The implementation steps that follow will be based on the assumption you are logged into your account in order to take advantage of these features. You have an option to create an account and to log in, which would allow you to save, name and search your work. Go to and follow the link to Start Graphing. Internet browser or Desmos Graphing Calculator app.Laptop or a mobile device (Android or iOS).Allows easy sharing of demonstrations with other users.Requires easily acquired technology skills on part of the users.Demonstrations and activities can be pre-built.Allows static and dynamic graphic demonstrations and quantitative analysis of 2-dimensional models. An open and free resource, without a registration or subscription requirement.It has a powerful built-in calculator tool and a slider tool that allows the user to create dynamic visuals exemplifying change or drawing attention to particular components. It allows the user to plot and label points on the Cartesian plane, demonstrate solutions to equations and inequalities, graph functions and create regression models from data sets, among other capabilities. 1)ĭepending on which specific decimals Desmos chooses to plug in, you'll get different looking graphs.Student exploration of functions and their graphs with Desmosĭesmos Graphing Calculator is an open online tool with extensive numerical and visual versatility. $3.12 = \frac$, so we're taking an odd power of the 25th root of -1 (i.e.This seems to be based on reduced fraction representations of the decimals: Desmos is perfectly happy to take some random decimals and plug them into $(-1)^x$, such as: Roughly speaking, Desmos breaks up the $x$-axis of the viewing window into a bunch of discrete, evenly spaced points, probably one for each pixel, and plugs those values into the function. Unfortunately when I tried to show this off in class on another similar computer I wasn't able to get anything to show up (it probably depends on screen resolution!) On Desmos on my browser the graph of $(-1)^x$ fluctuates between plotting barely any points, one almost completely filled in line, and two almost completely filled in lines depending on the width of my browser window.
