Arguments

ARGUMENT = CLAIM + WARRANT ARGUMENT - a statement made with sound reasoning. Every argument has two key parts: CLAIM - the controversial statement being made. WARRANT - the justification for the claim. ARGUMENT = CLAIM + WARRANT “My CLAIM is ___________ and my WARRANT is _____________________”

ARGUMENT = CLAIM + WARRANT Activity #1: Soapbox Debate Name, Claim+Warrant The best movie is ______. The most important math topic is ___. ___________is the best method for solving the system: ARGUMENT = CLAIM + WARRANT

Which problem shows the BEST mistake?

Always, Sometimes or Never? ARGUMENT = CLAIM + WARRANT Activity #2: Circle Debate Summarize, Claim+Warrant Always, Sometimes or Never? Max gets a pay raise of 30%.  Jim gets a pay raise of 25%.  So Max gets the bigger pay raise. When you cut a piece off a shape, you reduce its area and perimeter. and are co-terminal on the Unit Circle. ARGUMENT = CLAIM + WARRANT

In the figures shown, the perimeters of the square and equilateral triangle are 24cm. The circumference of the circle is also 24cm. Claim 1: The area of all three shapes is the same. Claim 2: The area of the square is easiest to calculate. Claim 3: The area of the triangle is greater than the area of the circle.

ARGUMENT = CLAIM + WARRANT Activity #3: Point. Counter-point. Would you rather….(a) Have crayons for teeth (b) Have spaghetti for hair Would you rather solve this problem… (a) Using a proportion “Find 45% of 80”(b) Making into a decimal and multiplying Claim+Warrant STEVE ARGUMENT = CLAIM + WARRANT
