“Instructional programs from Pre-K through grade 12 should enable all students to—

communicate their mathematical thinking coherently and clearly to peers, teachers, and others;

organize and consolidate their mathematical thinking through communication;

analyze and evaluate the mathematical thinking and strategies of others;

use the language of mathematics to express mathematical ideas precisely. “

Standard 3:

Construct viable arguments and critique the reasoning of others.

Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments. They make conjectures and build logical progression of statements and explore the truth of their conjectures. They are able to analyze situations by breaking them into cases, and can recognize and use counterexamples. They justify their conclusions, communicate them to others, and respond to arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose. Mathematically proficient students are also able to compare the effectiveness of two plausible arguments, distinguish current logic or reasoning from that which is flawed, and –if there is a flaw in the argument-explain what it is. Students of all grades can listen or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments.

Let’s gather some data!

The goal of the game is to be the first player to reach 100.

On your turn, roll the dice as many times as you would like, mentally keeping a running total of the sum. When you decide to stop rolling, record your total for that turn and add it to the total from any previous turns.

If a 1 comes up on one of the dice, your turn is over and you score 0 points for that round. If you roll a 1 on both dice, you lose your turn and ALL points.

Write a letter to your friend. Give advice about how to win and include mathematical evidence in support or your strategy.
