1. Module 3: Problem Solving: Look for a pattern Guess and check

2. Content Learning Targets Participants will solve problems by: Looking for a pattern Using guess and check Participants will justify their solutions

3. Language Learning Targets Participants will define: Sequence Pattern Guess and check Conjecture Verification

4. Problem Solving Activity Look for a pattern Numeric sequences Geometric sequences Sequences in nature Pascal’s triangle

5. Guess and Check Guess and check is an important problem solving strategy used by mathematicians and engineers. Mathematicians will use this strategy with differential equations. The difference between guess and check in the classroom and in research is that in the classroom, there is usually a known solution to the problem and in research the solution is unknown.

6. Guess and Check Conjecture and Verification Understand the problem and the requirements or restrictions of the solutions Record each conjecture and the result Verify the validity of each result against the requirements of the solution Explain the merits of the solution

7. Problem Solving Activity guess and check Thinking of a number Grandpa at the movies Jelly Beans
