Annotating a picture!

Here's another way to have your students show what they know!  Have them use a Google drawing and let them annotate with boxes and arrows!  For younger students, you could create a template and how them move the boxes to show their understanding.  On Friday, I tried this with a third grade class (I created a drawing, added the boxes, and then made a copy for them in Google Classroom).  I worked well- the students were able to drag the boxes and label the image.
For more ideas on using Google drawings, please see the blog post here from Paul Gaffney.
