How to recognize some common types of algebra word problems and how to solve them step by step:
Age Problems usually compare the ages of people.
They
may
involve a single person, comparing his/her age
in the past, present or future.
They may also compare the ages
involving more than one person.
Average Problems involve the computations for
arithmetic mean or
weighted average of different quantities.
Another common type of average problems is the
average speed computation.
Coin Problems deal with
items with denominated values.
Similar word problems are
Stamp Problems and
Ticket Problems.
Consecutive Integer Problems deal with
consecutive numbers.
The number sequences may be
Even or
Odd, or some other simple
number sequences.
Digit Problems
involve the relationship and manipulation of digits in numbers.
Distance Problems
involve the distance an object travels at a rate over a period of time.
We can have objects that
Travel at Different Rates, objects that
Travel in Different Directions or we may need to find the distance
Given the Total Time
Fraction Problems
involve fractions or parts of a whole.
Geometry Word Problems
deal with geometric figures and angles described in words.
This include geometry word problems
Involving Perimeters,
Involving Areas and
Involving Angles
Integer Problems
involve numerical representations of word problems.
The integer word problems may
Involve 2 Unknowns or may
Involve More Than 2 Unknowns
Interest Problems
involve calculations of simple interest.
Lever Problems
deal with the lever principle described in word problems.
Lever problem may involve
2 Objects or
More than 2 Objects
Mixture Problems
involve items or quantities of different values that are mixed together. This involve
Adding to a Solution,
Removing from a Solution,
Replacing a Solution,or
Mixing Items of Different Values
Motion Word Problems are word problems that uses the distance, rate and time formula.
Number Sequence Problems
use number sequences in the construction of word problems. You may be asked to find the
Value of a Particular Term or the
Pattern of a Sequence
Proportion Problems
involve proportional and inversely proportional relationships of various quantities.
Ratio Problems
require you to relate quantities of different items in certain known ratios, or work out
the ratios given certain quantities.
This could be
Two-Term Ratios or
Three-Term Ratios
Symbol Problems
Variation Word Problems may consist of
Direct Variation Problems,
Inverse Variation Problems or
Joint Variation Problems
Work Problems
involve different people doing work together at different rates.
This may be for
Two Persons,
More Than Two Persons or
Pipes Filling up a Tank

Example:
Devon is going to make 3 shelves for her father. She has a piece of lumber 12 feet long. She wants the top shelf to be half a foot shorter than the middle, and the bottom shelf to be half a foot shorter than twice the length of the top shelf. How long will each shelf be if she uses the entire 12 feet of wood?
