Anyone that knows me can tell you how much I LOVE emojis.
So it shouldn't come as a surprise that I found this easy site called Emoji Builder, to create your own. Just pick a face and other choices on the left side menu such as eyes, mouth, etc.
then adjust using the right side menu
and save it as a PNG file to be used anywhere. Students can use these in assignments as well (especially younger age and ESL students that images may be easier to use than words).
