Students focus on interpreting, creating, and using ratio tables to solve problems. They also relate ratio tables to graphs as two ways of representing a relationship between quantities.Key ConceptsRatio tables and graphs are two ways of representing relationships between variable quantities. The values shown in a ratio table give possible pairs of values for the quantities represented and define ordered pairs of coordinates of points on the graph representing the relationship. The additive and multiplicative structure of each representation can be connected, as shown: Goals and Learning ObjectivesComplete ratio tables.Use ratio tables to compare ratios and solve problems.Plot values from a ratio table on a graph.Understand the connection between the structure of ratio tables and graphs.
Words, numbers, pictures, diagrams, graphics, charts, and tables belong together. For example, good maps routinely integrate words, numbers, artwork, grids, and measurement scales. The fourth principle for the analysis and presentation of data is to completely integrate words, numbers, images, and diagrams. Tables of data can be thought of as paragraphs of numbers and can be tightly integrated with the text for the convenience of reading rather than segregated in an appendix. Annotate images and tables in your presentations with explanations of what is going on. When presenting text and data analysis, this integration can be accomplished in layers. At first, the data can be presented as standalone points to cleanly and clearly show the data. Then, layering techniques can be employed to add the other information to the presentation.
