So, to try to counter this, I tried to lower the entry point by starting with more basic graphs. Here’s the link:Īfter doing the lesson in class many times, I’ve found that students get confused pretty quickly. With the launch of the amazing Desmos Activity Builder, I made (with the help from the Desmos team) a new and improved version of the activity. What suggestions do you have to improve the game? Would you like to create a hole as well? Feel free to leave any comments. This will allow the students to determine the slope of the path taken by the ball if the teacher wants to go that direction with the lesson.įinally, in order to really ramp up the task, the teacher could have the students create their own hole for others to play on. Instead of using equations, students could simply choose coordinates where the ball needs to hit and then put them in a table. I set up the ball to have a trailer line in order to display the path taken ( credit Desmos for that idea). The game could also be used with simpler concepts as well. Other variations of the equation would have worked as well. For example, in the picture above, the student could have gone to the left instead of the right. I like this activity because there are multiple ways to approach the equations. This will allow them to explore linear equations with domain and range. My initial thought for the game is to have the students create linear equations that hit different points on the boundaries until the ball goes in the hole. Hole 5 via Desmos (I simplified it a bit).I decided to create a putt putt golf game using Desmos graphs. That combined with Masters fever and Fawn Nguyen’s miniature golf problem led to the following. Maybe you’ve spent five minutes reading and thinking about these time-saving shortcuts.I got the itch to create a few Desmos games after reading through some of Nora Oswald’s blog. Head over to the other activity and paste. Select the screen you want to copy and use your computer’s standard keyboard shortcut to copy it. For today’s final tip, imagine you have a screen in one activity that you’d like to have in a different one. But don’t worry we’ll warn you about that rather than wreck your stuff.)Ĭopying screens. (Caution! This feature only works if your source graph has no folders because we don’t currently support folders inside of folders. You can put another graph into a second folder, creating a mashup of two graphs if you’d like. Do the same thing, but paste that URL into a folder label. Putting a graph into a folder in an activity graph. (Caution! This will overwrite everything else in the Activity Builder graph, but don’t worry you can undo.) Just copy the URL from a graph you have open at /calculator, and paste it into the expression list in a graph on an activity builder screen that you’re editing. Instead, scroll down to the bottom of your expression list and click the “edit graph on desmos” link. If you’ve built a graph in Activity Builder, you might want that graph outside of Activity Builder for any one of many reasons. In that case, you’ll want to click the gear at the top of the expression list, then the page icon. Maybe you want a second blue, dotted parabola to match your first one. But sometimes you want to preserve a whole bunch of settings, too. You can use Select All and then Copy and Paste on expressions in the expression list. This second tip is still for the graphing calculator in general. Define a collection of points as ( x, y) pairs and then use those points to draw a polygon.Īlternatively, you can define your points using a list of x-coordinates and a list of y-coordinates, then feed those lists to the polygon function.Ĭopying expressions. This first tip isn’t strictly an Activity Builder tip it applies to the graphing calculator wherever you’re using it. If you’re a regular user of Activity Builder, I hope there is something new for you on the list, just as there was for me. So I put out a quick call to the rest of my colleagues, and the result is the following list. My colleague Sean Sweeney suggested a post on time-saving tips in Activity Builder, to share with all who work with this tool.
