Strategic Thinking

• For example, when grocery shopping some people visit the “50% off” shelf first, and avoid the expensive frozen food aisle. Both parts of this plan can help shoppers save money.

Pair Share

• Pair up.• Spend a minute thinking of a plan or

strategy you use in everyday life. You might consider how you work, clean, shop, budget, drive, or study.

• Share your plan with your partner. Be sure to tell your partner what the goal of your plan is – what are you accomplishing that might be difficult without the strategy?

Plans Are Important

• When reading, you need a plan. It’s important to know–What you are reading– Your purpose for reading– A reading strategy: MAPPS

• A reading plan will help keep you from “reading in circles.”

MAPPS: A Plan for Reading

Just as it is important to have a road map while

driving, it is also important to have a map for reading.

MAPPS: A Plan for Reading

MAPPS

• Ask questions as you read; and search for answers in the reading.

• Mark the answer to each question associated with other MAPPS levels About, Point, and Proof.

MAPPS

• The topic answers “What is the reading about?”

Read the title.

Look for repeated words and mark them

as you read.

Look for related words and pronouns.

Finding the Topic

MAPPS

• The point of the reading is the main idea.

• The main idea limits the topic to what the author wants to discuss.

Topic Sentences

• When the topic and the main idea appear in a single sentence, that sentence is called the topic sentence.

T MI TS topic plus main idea equals topic sentence

Finding Topic Sentences• The topic may come before or after the

main idea.

• The topic can be more than a single word.

• There may be words in the topic sentence that report the topic and main idea.

The main idea narrows the topic to the specific point the author wants to discuss

The topic is a broad, general idea.

The supporting details support the main idea with even narrower, more specific ideas.
