Chunking

Chunking is…

Chunking is a strategy that helps us to improve our short time memory.

Why do we need strategies?

George A. Miller And “The Magical Number Seven, Plus or Minus Two”

Our short time memory can remember from five to nine different groups of information.

Some examples

Phone Numbers3-1-6-5-7-8-8-3-6-6

Id.Numbers1-0-3-0-1-9-8-9-2-9-3

Grocery lists:Bread, Eggs, Milk, Flour, Bacon, Chicken, Cereal, Onion , Apples, Oil, Oranges, Fish, Garlic, Cofee, Cookies

So, what can we do?

We can “chunk” or split the information in groups

3-1-6-5-7-8-8-3-6-6 316-57-88-366 1-0-3-0-1-9-8-9-2-9-3 1030-1989-293

Bread, Eggs, Milk, Flour, Bacon, Chicken, Cereal, Onion , Apples, Oil, Oranges, Fish, Garlic, Cofee, Cookies• Meat -{ Bacon, Chicken, Fish}

• Fruits-{Apples, Oranges}• Vegetables-{Onion, Garlic}• Things for Breakfast-{Bread,

Eggs, Milk}

•Pancakes need-{Flour, Oil}•When I am in a rush I like to eat-{Cofee, Cookies}

Chunking is good because…

Our brain works better with information that has a structure.
