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)

7th Grade Mathematics Vocabulary• Unit 1: Operations with Rational

Numbers

• Additive Inverse• Multiplicative Inverse• Absolute Value• Integers• Long Division• Natural Numbers• Negative Numbers• Opposite Numbers• Positive Numbers• Rational Numbers• Repeating Decimal• Terminating Decimal• Zero Pair

• Unit 2: Expressions and Equations

• Variable • Numerical Expression• Algebraic Expression• Term• Coefficient• Constant• Equation• Inequality

7th Grade Mathematics Vocabulary

• Unit 3: Ratios and Proportional Relationships

• Fraction• Multiplicative inverse• Percent rate of change• Ratio • Proportion• Scale factor

• Unit 4: Statistics

• Box and whisker plot• Frequency• Grouped frequency table• Histogram• Inter-quartile range (IQR)• Maximum value• Mean absolute deviation• Mean• measures of center• Measures of spread• Median• Minimum value• Mode• Mutually exclusive • Outlier• Range• Sample• Simple random sampling• Stem and leaf plot

7th Grade Mathematics Vocabulary• Unit 5: Geometry

• Adjacent angle• Circumference• Complementary angle• Congruent• Cross-section• Irregular polygon• Parallel lines• Pi• Regular polygon• Supplementary angle• Vertical angles

• Unit 6: Probability

• Chance process• Compound event• Empirical• Event• Experimental probability• Independent events• Probability• Probability model• Relative frequency of outcomes• Sample space• Simple event• Simulation• Theoretical probability• Tree diagram

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)

Honor the Compact

• The school/ parent compact serves as an agreement that you, your child, and the school will work together to achieve the best education possible for your child.

• By working together as a team, we can make a difference!
