Une ressource pédagogique intéressante disponible sur le site de la NCTM.
« Need a pentagonal pyramid that’s six inches tall ? Or a number line that goes from ‑18 to 32 by 5’s ? Or a set of pattern blocks where all shapes have one-inch sides ? You can create all those things and more with the Dynamic Paper tool. Place the images you want, then export it as a PDF activity sheet for your students or as a JPEG image for use in other applications or on the web. »
