Verbal and problem solving
There are two steps to solving math word problems:
1. Translate the wording into a numeric equation
that combines smaller "expressions"
2. Solve the equation!
Suggestions:
* Read the problem entirely
Get a feel for the whole problem
* List information and the variables you identify
Attach units of measure to the variables (gallons, miles, inches, etc.) * Define what answer you need,
as well as its units of measure
* Work in an organized manner
Working clearly will help you think clearly
* Draw and label all graphs and pictures clearly
* Note or explain each step of your process;
this will help you track variables and remember their meanings * Look for the "key" words (above)
Certain words indicate certain mathematical operations:
Math expressions (examples):
after you review the keywords, test yourself
addition: 5+x| subtraction: 5-x|
multiplication: 5*x; 5x| division: 5 ÷ x; 5/x|
Exercise: ("mouse over" the block for answer)|
Key words for addition +
increased by; more than; combined together; total of; sum; added to| What is the sum of 8 and y?| 8 + y|
Express the number (x) of apples
increased by two| x + 2|
Express the total weight of
Alphie the dog (x) and Cyrus the cat (y)| x + y|
Key words for Subtraction -
less than, fewer than, reduced by, decreased by, difference of| What is four less than y| y - 4|
What is nine less than a number (y)| y - 9|
What if the number (x) of pizzas
was reduced by 6?| x - 6|
What is the difference of my weight (x)
and your weight (y)| x - y|
Key words for multiplication * x or integers next to each other (5y, xy): of, times, multiplied by|
What is y multiplied by 13| 13y or 13 * y|
Three runners averaged "y" minutes.
Express their total running time:| 3y|
I drive my car at 55 miles per hour.
How far will I go in "x" hours?| 55x|
Key words for division ÷ /

...levels, K-10 are Critical Thinking and ProblemSolving. We adopt the definition of critical thinking by Scriven and Paul (1987): Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action. On the other hand, we define...

THE PROBLEM AND ITS BACKGROUND
Introduction
The history of science and math are interrelated. The people who shaped science are also important in mathematics. As in science, the early history of mathematics is sketchy. We know that the lunar and solar cycles were counted by the Babylonians and Egyptians in an organized fashion. Early Indian mathematicians are credited with many astronomical observations as well as the beginning of algebra. The use of decimals...

...Problem-Solving
Despite what folks accomplish as a profession or where they exist, most folks use the majority of their waking hours, at a workplace or at home, tackling situations. Most situations people challenge are little, some are substantial and complex, yet they need to be settled in a tasteful manner. There are a few definitions of a situation or how one individual may distinguish a situation. A situation is a chance for development. A situation may be a...

Younger Sibling Problems
Younger siblings can be a problem that will lead to a bigger problem, your parents being angry at you for never being home. My younger brothers, CJ and Colin, are obnoxious and very annoying. CJ is six years younger than me and Colin is eight years younger than me. You wouldn’t think that they would be a problem to me since there is such an age difference between us,...

...In my efforts to solve a problem I have often begun by identifying the one issue that affects me and focus on the individual tasks that led to the problem attempting to use logical and critical thinking. I have hit upon the realization that this focus works well with simpler problems that need immediate clarification but it has proven appropriate that problems that are more difficult and require a more long-term and elaborate answer...

...Decision-Making & ProblemSolving
“Thinking is any mental activity that helps formulate or solve a problem, make a decision, or fulfill a desire to understand. It is a searching for answers, a reaching for meaning.” –Vincent Ryan Ruggiero

...workplaces. Firstly, causes, which are the lack of understanding probably due to biases, common attitudes and tools of communication worth an in-depth investigation, followed by consequences of the problem, that is confusion, mistanding, and even confilcits of each other. Ultimately, solutions of the problem due to generational differences in a workplace will be delineated.
Communication is the conveying of ideas together with absorbing one’s opinions (Sinclair,...
