2 Consider the diagram on the previous slide. What are some questions we could ask?

3 LINE MATH How many lines? What is 4 x 3 in line math?

4 INTERSECTION MATH Ideas from James Tanton

5 INTERSECTION MATH How many intersections are there? What is 4 “x” 3 in intersection math? Is intersection math commutative? What is 2034 “x” 825 in intersection math? What is m “x” n?

6 RECTANGLE MATH How many rectangles can be formed from an m x n lattice assuming we are only counting rectangles that are vertical or horizontal?

7 DINNER PARTY MATH The product of two numbers in dinner party math is the number of combinations of four people. The four people must be two females and two males. What is m x n in dinner party math if m is the number of males and n is the number of females?

8 RELATIONSHIPS AND EXTENSIONS Are there any similarities within intersection math, rectangle math, and dinner party math? If so, why? If not, why not? What other questions can we ask?
