Note that the 5’s, 6’s, and 10’s are groups of 4 Find your partner(s) and choose a table to sit at. Leave your cards face up on the table, and I will come by and collect them later. Introduce yourself, as necessary, and share your thoughts/plans for homecoming and the weekend. Then begin the practice problems, start with the problem number that matches your card, then go on (or back) to the remaining problems. Do as many as you can in the time you have.

Burger Math

How much does a 100X100 cheeseburger cost? You may choose to begin by asking students about the cost of a 100×100 or start with something smaller like a 3×3.  I have found that students with emerging skill sets need to begin with a 3×3 to establish that it is not the same thing as ordering 3 cheeseburgers or a Double-Double and a cheeseburger.  Eventually you want them to be able to generalize the cost of a NxN burger. As much as possible, you want students to do all of the discovery.  Make sure to have a conversation about what is on a 100×100.  Essentially it is a cheeseburger with 99 additional beef patty and cheese layers or a Double-Double with 98 additional beef patty and cheese layers.  There are no additional buns or toppings such as lettuce, tomato, onions, or spread. Hint: first think about the cost of a 3x3

How would you describe what ingredients are in a 3×3? How would you describe what ingredients are in a 3×3? (To help students realize it is a cheese burger with all the cheese burger toppings plus 2 additional layers of beef patties and cheese) How can we figure out how much an additional beef patty and cheese slice cost? What are the differences between a cheeseburger and a Double-Double? Where do you see the cost of the extra layer mentioned in the words in the table, graph, and symbols? Where do you see the cost of the cheeseburger in the words in the table, graph, and symbols? How would your answer change if you had started with a Double-Double and added 98 layers versus a Cheeseburger and added 99 layers? How would you describe what ingredients are in a 3×3? How can we figure out how much an additional beef patty and cheese slice cost?
