How do I create a Desmos ellipse item?
In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a Desmos ellipse item. A Desmos elipse question requires students to plot an ellipse on a graph by moving the center point and a point on the ellipse. After you select the question type, you can use the math editor to add details for the question, view a student preview, and validate answers.
You can create any item type through the Item Editor. You can also use the Item Editor to add passages, add item-level tools, and save the item. To open and use the Item Editor, learn more about:
- Creating an item in your personal item bank
- Creating an item in the district item bank as an administrator
- Creating an item from within an assessment
Note: If you do not see the Desmos Items (Paid Upgrade) section in the Question Type drop-down menu, your institution does not have a paid Desmos upgrade.
