You will have a chance to confer with your table partner. Each of you need to write the following:

_________________________________________

Write down three observations- things that you can actually see that you believe are very important to the picture you are viewing.

Write down three inferences- things that you suppose are likely to happen based on what you see in the picture.

_________________________________________

Your observations and inferences do NOT have to be the same as your partner.
