Patterns Portfolio

The in this unit titled "Patterns" we learned and covered a lot of things. Some of the key concepts we went over are In and Out tables, order of operations, summation notation, consecutive sums, conjecture and proof, geometry, recursive functions, positive/negative numbers and algebraic expressions. We used in and out tables to organize data so that we can see patterns.

By organizing it and looking at the in then the out it made it easier to find a pattern. Orders of operations were used to correctly find the correct order and answer to a problem that contained many operations. To help us remember the order we used the acronym PEMDAS (Parentheses, Exponentiation, Multiplication/Division, Addition/Subtraction) which was made easier to remember by using "Please Excuse My Dear Aunt Sally". We also learned about summation notations which taught us things such as the sigma. Consecutive sums showed us how we can use consecutive numbers to get a sum such as the 1-2-3-4 pattern. We also learned about geometry and how to measure angles and finding angles on shapes. Proofs are used to make sure your answer is correct and how you know its complete. We also learned how diagonals can affect the sum of the angles of a polygon. We used algebraic expressions and learned about variables and how to find the answer to certain problems.

Math is a very important subject to learn. I believe that math is a subject in which you learn about properties and relationships of things using numbers and sometimes symbols. You learn about things from shapes and measurements to patterns and relationships. Math is usually a difficult subject with lots of rules that you take during most or your entire educational career. Math can be boring sometimes, but it can
