Unit 1 Review

- one mini whiteboard

- one whiteboard marker

- one paper towel

GROUP MATERIALS

1) Ms. Lee picks a student randomly.2) Selected student chooses a question.3) ALL students solve/answer question on their

paper SILENTLY for 2 minutes.4) Group discusses question and writes FINAL

WORK & SOLUTION on whiteboard.5) When Ms. Lee calls “TIME,” all groups raise

their whiteboards.6) Groups with the correct answer earn points.

INSTRUCTIONS

- Students take turns writing on the whiteboard. After each question, whiteboard must be rotated CLOCKWISE.

- Follow instructions!- Ask for hints ONLY when your group

absolutely needs one. Hints cost $50.- Don’t write/draw anything unnecessary.

Don’t use the markers on anything other than the whiteboards.

Does this graph represent a function or

a non-function?How do you

know?


Click to see answer

The graph represents a function. Every input (x) has

a unique output (y).
