Agenda

Learning Targets I can use inductive and deductive reasoning to solve problems.

Reasoning in Mathematics…For each of the following:

1. Repeat the procedure for four different numbers of your choice. Write a conjecture (hypothesis…) that relates the result of the process to the original number selected.

2. Represent the original as n, and use deductive reasoning to prove the conjecture in part (1).

• Select a number. Multiply the number by 4. Add 8 to the product. Divide the sum by 2. Subtract 4 from the quotient.

• Select a number. Add 5. Double the result. Subtract 4. Divide by 2. Subtract the original selected number.

• Select a number. Add 3. Double the result. Add 4. Divide by 2. Subtract the original selected number.

Final Draft of PaperTask

o Find the flaw in the following statement:o In 1980, Miss Damiano was

examining some trees in the forest of Mt. St. Helens, and she noticed that all the trees were a grey-black color on the side facing the mountain. She concluded that all trees on mountains must have grey coloring on the side facing the mountain.
