Practice 3. Construct viable arguments & critique the reasoning of others.

Practice 3. Construct viable arguments & critique the reasoning of others.
• Analyze problems and use stated mathematical assumptions, definitions, and established results in constructing arguments.
• Justify conclusions with mathematical ideas. • Listen to the arguments of others and ask useful
questions to determine if an argument makes sense. • Ask clarifying questions or suggest ideas to
improve/revise the argument. • Compare two arguments and determine correct or
flawed logic.

Roles• Grid Designer – Puts the colors in the grid.• Checker
– Checks the Grid Designer follows the rules– Make sure the Guesser provides a reason for each
guess after the first color tile is revealed.• Guesser – Asks the Grid Designer “A Yes or
No” to determine the grid.• Recorder
– Records all of the reasons given by the Guesser– Records the number of guesses.

Before you begin …• Predict the fewest number of guesses needed
for the Guesser to determine the grid design.
• The roles will rotate.
• Make a claim, “The fewest number of guesses needed to determine the grid design is ___”.
• Keep playing until you have enough evidence to support your claim.
• If you think a 3 × 3 is too easy, do a 4 × 4. 23

Before you begin …How many pets do you have?Here are your roles:• Grid Designer – the most pets• Checker – elbow partner of Designer• Guesser – sitting opposite of the
Designer• Recorder – the remaining personRock-Paper-Scissors breaks any tie.The next Grid Designer is to the right of
the current Grid Designer . 24

As you begin …The Grid Designer and the Guesser draw a 3 × 3 grid
on your whiteboard.
The Grid Designer fills in the grid, and the Checker verifies it.
The Checker also listens for a reason for each guess after the first guess. If they do not hear a reason, they show the .
The Recorder writes all the reasons and the number of guess on a piece of paper. The paper gets passed to the next recorder.
