Developmental Mathematics: Content HighlightsPrefaceixDevelopmental Mathematics:Content HighlightsNew FeaturesStrategies for Academic SuccessChapter ProjectsA new section has been included to help studentshone their skills in note taking, time management, testtaking, and reading. This section also provides tipsfor improving memory, overcoming test anxiety, andfinding a math tutor. (See page 19 for more)This new feature promotes collaboration and showsstudents the practical side of mathematics throughactivities using real-world applications of the conceptstaught in the chapter. (See page 24 for more)Strategies for Academic Success Note TakingGeneral TipsExample:RRFO Write the date and the course name at the top ofeach page. Write the notes in your own words and paraphrase. Use abbreviations, such as ft for foot, # for number,def for definition, and RHS for right-hand side. Copy all figures or examples that are presentedduring the lecture. Review and rewrite your notes after class. Do thison the same day, if possible.There are many different methods of note taking and it’salways good to explore new methods. A good time to tryout new note-taking methods is when you rewrite yourclass notes. Be sure to try each new method a few timesbefore deciding which works best for you. Below are threenote-taking methods you can try out. You may even findthat a blend of several methods works best for you.Note-Taking MethodsOutlineAn outline consists of several topic headings, eachfollowed by a series of indented bullet points that includesubtopics, definitions, examples, and other details.Keywords:RatiosNotes:1. Comparison of twoquantities by divisiona2.3.b, a : b, a to bCan reduce4. Common units can cancelSummary: Ratios are used to compare quantitiesand units can cancel.MappingThe mapping method is the most visual of the threemethods. One common way to create a mapping isto write the main idea or topic in the center and drawlines, from the main idea to smaller ideas or subtopics.Additional branches can be created from the subtopicsuntil all of the key ideas and definitions are included.Using a different color for subtopic can help visuallyorganize the topics.Example:Comparison of quantities by divisionCan bereduceda to baba:bThe split page method divides the page vertically into twocolumns with the left column narrower than the rightcolumn. Main topics go in the left column and detailedcomments go in the right column. The bottom of the pageis reserved for a short summary of the material covered.1.Find two other note taking methods anddescribe them.2.Write five additional abbreviations that youcould use while taking notes.Take Me Out to the Ball Game!An activity to demonstrate the use of percents and percent of increase or decrease in real life.The Atlanta Braves baseball team has been one of the most popular baseball teams for fans not only from Georgia, butthroughout the Carolinas and the southeastern United States. The Braves franchise started playing at the Atlanta-FultonCounty Stadium in 1966 and this continued to be their home field for 30 years. In 1996, the Centennial Olympic Stadium thatwas built for the 1996 Summer Olympics was converted to a new ballpark for the Atlanta Braves. The ballpark was namedTurner Field and was opened for play in 1997. In, the braves moved to a new stadium named SunTrust Park.Round all percents to the nearest whole percent.1. The Atlanta-Fulton County Stadium had aseating capacity of 52,769
