Discussion Forum Module 1 - Fractions (Part 1) This assignment was designed for you to reflect on what you have learned and expand your knowledge in a collaborative, communicative environment. The initial post is due on August 5, and responses to other comments are due on August 7. This activity is worth 10 points. Your participation will be graded using the discussion forum rubric. You will receive the scores and instructor's comment for this activity by August 10. Instructions Step 1. Select one of the following questions and respond to it in a short essay format (one or two paragraphs or longer). Step 2. Post your response to the discussion board. Please include the question you selected in the subject line of your message. If you wanted to include pictures in your post, create bitmap files (extension bmp) using Paint, a software available on all PCs under Programs - Accessories. Step 3. Read the posting of other students in the class and answer at least one of them. At least one such response should address a question different from what you selected. This activity will be graded using the following rubric. Discussion Forum Rubric Points Description 2 points The response addresses the topic. 4 points The response reflects critical thinking. Student arrives to the correct conclusions and presents clear arguments to support them. 2 points The response is written in standard English, in full sentences, using correct grammar, spelling, and punctuation. 1 point All instructions were followed. 1 point Student responds to at least one other discussion thread. Late posts will lose 1 point with each day of delay. Discussion Questions Q1. Consider the fractions 5/9 and 4/7. Explain why it is not immediately obvious which of these two fractions is greater. Use what we have learned in this module to determine the answer to this question. Q2. Explain the concept of decimals in terms of fractions. For example, how can we write the decimals 0.1, 0.03, and 0.0002 as fractions? If you are relying on some source, quote it. Q3. Suppose we first take of a quantity Q and then we take of the result. What single fraction could express the result? Start with a suitable quantity (how could we find one?) and demonstrate your answer using that quantity. Also, devise a geometrical argument supporting your answer. Q4. The concepts in this module naturally occur in many aspects of life. Think about your major or your job (past or current) or your personal life and interview friends and relatives about their profession. As a result of these interviews, present (at least) two real-life examples where fractions and what we learned in this module naturally occur. Explain clearly these examples and the mathematics behind them. This page was last updated on July 22, 2013.
