On the Varsity platform, they have a stickers option. Students can click on a sticker to use to mark things, like multiple choice questions. I use them for orthographic mapping. The options are a range of smiley faces, a checkmark, an X, a star, or a unicorn. They come in handy, and are quicker to mark with than a drawing pencil. For your pencil, to get this effect, you have to make a really think line, and you can make a dot. But that takes a lot of time. Also, this is different than emojis, it's a way of marking, and not with in a text, it's separate. Thank you!
