In the sample activity shown below, students are to click
on the green circle and drag it to the capital letter which matches the
lowercase letter. Anything you wish to match can be done in this manner,
however, the activity would best be done as a whole class activity. Students
could drag the green circle to any other shape, and will need to get feedback
from the teacher, not from the Excel worksheet.

If you have thought of a way to use this in your classroom,
let's get started.
