Visuals can be cheating

Visuals can be deceiving. The difference here is in the distance.

SO WHAT DO WE LEARN?

Do not assume that all our students see the same things that we thought they would see !

Even graphs, diagrams, etc.

If you watch the above images from your seat in front of the computer,
Mr. Angry is on the left, and Ms. Peace is on the right.

Now get up from your seat, and move back 3-5 m and tell what you see.
