Mathematical Literacy

“Mathematical literacy is an individual’s capacity to identify and understand the role that mathematics plays in the world, to make well-founded judgements, and to engage in mathematics in ways that meet the needs of that individual’s current and future life as a constructive, concerned, and reflective citizen.”

The Organization for Economic Cooperation and Development (1999)

Types of Mathematic Text

Forms

Information sheets (data)

Price sheets/catalogs

Invoices and billing statements

Advertisements

Tables, charts, graphs

Diagrams

Maps

Calendars

Recipes

Abilities Needed for Math Literacy

Students need skills in…..1. Mathematical thinking and reasoning2. Mathematical argumentation (proofs)3. Mathematical communication4. Modeling5. Problem posing and solving6. Representation7. Symbols8. Tools and technology

Mathematic Language as Technical “Jargon”

A developed language to describe abstract concepts of numbers and space

Vocabulary Mathematical terms vs. everyday words

Similar - alike, congruent, equivalent, equal

Addition – increase, decrease, no change

Zero – none, not having any

Small words, big differences The area “of” a triangle, meaning the “inside” a triangle.

Strategies to Improve ML

Strategic reading of word problems K-N-W-S model Vocabulary practice Determining the importance of the text Guided reading (questioning) of a math text

Strategic Reading

Strategies

Before Reading • Preview text (title, graphics, order of print)• Access prior knowledge• Purpose for reading (what questions to ask)

While Reading • Check understanding of the text (vocabulary, paraphrasing)

• Monitor comprehension through context clues,visualizing, inferencing, and predicting

• Apply existing knowledgeAfter Reading • Summarize what was read

• Evaluate the information provided in the text• Makes the appropriate applications of the idea

K-N-W-S Model

K N W SWhat facts do I KNOW from the information in the problem?

What information do I NOT need?

What does the problem WANTto find?

What STRATEGYor operations will I use to solve the problems?

Word Problem Practice

Video Heaven rents movies for $3 a piece per night. The store also offers a video club plan. The plan costs $100 per year and allows unlimited rentals at $1 per movie per night, plus two free rentals per month. How many movies must you rent in a year to make the video club worthwhile?

Know the Facts

PARENTS: encourage your child

to “Get the Facts”Ask your child to help

you solve basic real life problems

Have your child explain how they came to their conclusion

Get the facts = PRACTICE

1. Flash cards2. Students roll two dice, then multiply the 2 numbers

they rolled together.3. Create a memory game–one card contains the

factors, the other contains the product.4. Dominoes-students draw a domino that is face

down. They multiply the dots on either side of the domino together.
