Drag 'n drop
One way to create dynamic math expressions in Graspable Math is to use the "insert" menu. If you want to turn static math expressions you found on the web into dynamic expressions, another way is to directly drag-and-drop them into the GM canvas. This works for many text or latex representations, as well as many of the pre-rendered math expressions on Wikipedia. Finally, you can drag and drop images to add them to a GM canvas worksheet.
