2. Objectives Content: I can demonstrate understanding of observations and inferences by identifying examples of each using a PowerPoint. Language: I can write to identify examples of observations and inferences using “The Boy in the Water,” and write to create my own examples of observations and inferences on an Observations and Inferences handout.

3. Let’s number Off I will give you a number!!!! Please record the number at the top of your paper (ISN).
