The following diagram shows the very nature of mathematics. Know the truth, with trial and error, and without the fear of facing more questions and It is done withĬuriosity, with a penchant for seeking patterns and generalities, with the desire to It has a language that differs from the ordinary speech. It is an art of geometric shapes and patterns, a tool in decision -making and Mathematics has always been perceived as a study of numbers, symbols, and Will also justify statements and arguments made about mathematics and mathematicalĬoncepts using different methods of reasoning. Write mathematical texts and communicate ideas with precision and conciseness. We will study mathematics as a language in order to read and Moreover, we willĭiscuss and argue about the nature of mathematics, what it is, and how it is expressed, Purely a bunch of memorized formulas and duplicated mathematical computations, butĪs a powerful tool used to understand better the world around us. Topics will allow students to go beyond the typical understanding of mathematics as Mathematics Language and Symbols and 1 Problem Solving and Reasoning. Section 1 is composed of the following: 1 Mathematics in our World 1. Governed by logic and reasoning, and an application of inductive and deductive This course begins with an introduction to the nature of mathematics as anĮxploration of unseen patterns in nature and environment, a rich language in itself Students should realize that no, this is not an actual running time but acts as a placeholder so that on June 1st the equation amounts to 15 minutes.Overview Welcome to the first module of GE 1 (Mathematics in the Modern World)! When using the a(0) term, ask students if there was ever a day Mallory ran 10 minutes. I ask students when we want to start adding the five minutes, and they are able to reason that this is not until June 2nd, thus creating the need to “back track” our equation. Make sure students understand the necessity of the (n-1) when starting with June 1st. In the debrief, highlight the fact that there are two ways to write the explicit formula (and in fact, there are infinitely many, since we could use any day in June as our “anchor”). Be ready to build on student thinking and use the debrief to discuss both methods. Both of these strategies lead to the same sum formula, though written slightly differently. This sum of 175 will occur 15 times since there are 15 pairings of days. Another strategy is to realize that the days can be summed in any order and the sum of the first and last day is the same as the sum of the second and second to last day, is the same as the sum of the third and third to last day, and so on. Students use the idea of her average run time to find the sum of all 30 days. This idea of a constant (common) difference is critical to the rest of this lesson and ties in important ideas about a constant rate of change and linear functions. We specifically ask for June 29th so students recognize that her running time on that day is exactly five less than her running time on the 30th. While students may use a recursive pattern to find the first few values in the table, they should quickly recognize the need to make use of structure to find values for days later in June. Students identify that her time increases by five minutes every day and use this to fill in her running log. Today students look at Mallory’s running times during the month of June to explore the idea of arithmetic sequences.
