Finding an approximate answer to a problem, but not the exact answer/value

Shown using equal sign with wavy lines

A problem solving principle that involves using comparisons to describe unfamiliar concepts

Example: explaining a parallelogram as a slanted rectangle

A problem solving principle that states that two things that are similar may not be the same (details are important)

Example: 2 right triangles with the same angles may have different side lengths

A problem solving principle that states that order matters when solving problems

Example: finding the median of a data set requires putting the values in ascending or descending order

A problem solving principle that involves disproving a statement using a single example

Example: 'right-handed people always bat right-handed' is disproven by one that bats left-handed

A problem solving principle that states that there are certain things that are always true

Example: a whole number multiplied by an even number will always be even

Round to nearest dollar: $5

$5 * 5 = $25

1. Visualize problem for understanding; determine what you are trying to solve

2. Write equations that will enable the problem to be solved

3. Solve

Monday-Friday: 5 cartons * 5 days = 25 cartons

Saturday and Sunday: 10 cartons * 2 = 20 cartons

25 + 20 = 45 cartons of eggs

10 items left = 3 pants + 3 hats + *x* shirts

*x* = 4 shirts remaining

60 shirts at start - *y* shirts sold = 4 shirts remaining

*y* = 56 shirts sold

60 shirts + 40 pants + 20 hats = 120 items

120 items - 10 items left = 110 items sold

110 items * $15 = $1,650.00 earned

The process of representing scenarios with examples

A formula that is used to represent a real-world problem

Represent phenomena in ideal (perfect) conditions, so not always 100% accurate
