Would you like to change you Seesaw Icon? Why not draw a picture, paint or collage a picture of yourself or even edit a picture in PicCollage (I've added my head to a sunflower! You could add a crown?) and upload to Seesaw and I'll change your Seesaw Icon.
Teachers can save the drawing to the camera roll. Tap the wrench. Select “Manage students.” Select the student. Select “Icon.” Select “Use Photo.” Choose the drawing. You could instead have students create an avatar in another app, save to camera roll, then use that for their icon.
