Classroom Expectations Jigsaw

• VOICE LEVELS: Tables 1, 3, 5, and 7– Why do we use different voice levels 0-4? What

are they? Give an example of when we would each voice level.

• CLASSWORK: Tables 2, 4, 6, and 8– How should independent work be completed

differently than partner or group work? What would be similar about independent, partner, and group work?

Finish Reading – POPCORN!!

• Finish reading “The Key to Identification”• Popcorn Reading Rules:

– Read at least 3 sentences– Pay attention!– You can call on someone more than once but not if

they were just reading before you (no ping-pong popcorn)

• Crash Course biology: Taxonomy
