Ratios are fractions that compare one part to another part. A proportion is two ratios multipled by each other to get the whole amount of the two. In my lesson, I plan to teach by using hands on material such as snap blocks to illustrate ratio and proportion that I may use, but I will encourage my students to find other methods and strategies for finding proportion.
Proportion brings in other concepts such fractions, ratios, and equivalence.
My lesson uses these concepts and applies them. My lesson is significant because it allows students to discover that there are many ways to show the same fraction, develop strategies for showing fractions using geometry and tables, and uses ratios and proportions. My lesson meets the NCTM Standards by exploring proportion by reducing and enlarging drawing using grids. The students are to use grids for graphing their proportions that they constructed using Snap Cubes. The learner will demonstrate an understanding and use of graphing, probability, and statistics.
