Part of this lesson has to do with creating a “Wordle.” Wordle is a free online tool used for creating “word clouds” from text that you provide/input. The clouds (i.e. brainstorm) give greater emphasis to words that appear more frequently in the source text. As a user, you can tweak your clouds with different fonts, layouts, and color schemes. You can print them out, or save them to your own documents to share with your students, staff, or parents. Visit http://www.wordle.net/ to get started! (See "For Teachers" folder for direct link).

Note: Before teaching this lesson, it is important that students have knowledge of a variety of graphs and how/when they might be used to display data.

Organize and display single-variable data in appropriate graphs and representations (e.g., histogram, circle graphs) and explain which types of graphs are appropriate for various data sets.

Determine when and how to break a problem into simpler parts.

Apply strategies and results from simpler problems to more complex problems.

Use a variety of methods, such as words, numbers, symbols, charts, graphs, tables, diagrams, and models, to explain mathematical reasoning.

Express the solution clearly and logically by using the appropriate mathematical notation and terms and clear language; support solutions with evidence in both verbal and symbolic work.

Evaluate the reasonableness of the solution in the context of the original situation.

Note the method of deriving the solution and demonstrate a conceptual understanding of the derivation by solving similar problems.

Develop generalizations of the results obtained and apply them in other circumstances.
