Information Inputs
 Numbers and Number Sense
 Measurements
 Geometric Sense
 Algebraic Sense
 Statistics and Probability


Information inputs are the content we want students to learn. In the pre K12 math curriculum, there are five of these content areas.
These are:
 Numbers and Number Sense
 Measurement
 Geometric Sense
 Algebraic Sense
 Statistics and Probability
Although these five areas make up the entire math curriculum, they are emphasized differently depending on the grade level. Each of these areas begins with simple ideas and progresses to more difficult ones. Other math subjects such as trigonometry and calculus extend the ideas to even higher levels.
