Family Fun Night December 6, 2012 FOCUS: Math Literacy

Reading and Math? One of the important functions of reading is the acquisition of information and one of the important aspects of mathematics is the manipulation of information so reading and math just naturally go together.

Why teach vocabulary? There is research supporting the connection between vocabulary development and success in mathematics. (Allen, 1999)

Vocabulary knowledge increases students’ reading comprehension. develops students’ knowledge of new concepts. improves students’ range and precision in writing. helps students communicate more effectively. develops students’ deeper understanding of words and concepts.

Some vocabulary words are found only in math (denominator, hypotenuse, polynomial, histogram). shared with science and other disciplines (divide, radical, power, experiment). shared with everyday language sometimes with different meanings and/or sometimes with comparable meanings in mathematics (fraction, similar, variable, median). (Rubenstein, 2007)

Genre: Expository MATH CONCEPTS Number Sense Ratios Patterns Measuring Estimating Data Analysis Tables and Graphs Geometry Reasoning and Logical Thinking Expository writing is used to inform readers about specific topics. This is done through giving direct information and proving that the information is correct by showing the reader what is applied to the specific ideals. Expository = Explain

Not another word problem! Typically, reading in the content area of math is assigned as independent work, and many students overlook it and attempt to solve problems by trying to mimic the examples in the text.

Mathematics Reading Keys 1. Read carefully and make sure each sentence makes sense. 2. Try to summarize what you read in your own words. 3. When you encounter a difficult word, try thinking of easier words that mean the same thing and substitute. 4. Talk over what you read with a partner to make sure you got it right, and to clear up anything you don’t understand. 5. Be on the lookout for things the author thinks you already know and things you have learned in mathematics before. 6. “Read” with a pencil by working the examples as you read them, and reread each section after trying the examples. 7. Make your own definitions for key terms and keep them in your math notebook. (Buehl, 2001)
