 Algebra:
A form of advanced arithmetic in which letters of the
alphabet represent unknown numbers. Children use simple
algebra when they solve a problem such as 4 + ? =7 (a
problem they would phrase as "4 + x = 7" when they get older
and begin to study algebra).
Arithmetic: A branch of
mathematics taught to youngsters in elementary school. It
deals with numbers and how to use them in the operations of
addition, subtraction, multiplication and division.
Classification: Identifying
ways in which objects are similar (such as color, size or
shape).
Geometry: A branch of
mathematics that deals with measurement, properties and
relationships of points, lines, angles, surfaces and solids.
For young children, geometry begins by recognizing shapes
and patterns; formal study begins later.
Mathematical reasoning:
Thinking through math problems logically in order to arrive
at solutions. It involves being able to identify what is
important and unimportant in solving a problem and to
explain or justify a solution.
Measurement: Determining the
length, area, volume, time and other quantities and using
the appropriate tools to do so. Units of measure include
inches, feet, grams, kilograms, pounds, tons, gallons,
liters, dollars.
Number sense: The ability to
recognize numbers, identify their relative values and
understand how to use them in a variety of ways, such as
counting, measuring or estimating.
Probability: The chance that
a given event will occur. It is an important area of
mathematics study and a subject to which young children can
be introduced through games of chance, such as coin tosses.
Statistics and data analysis:
The collection and analysis of numerical data. Counting
people in a census is a statistical activity. So is
computing a batting average or figuring the miles per gallon
that your car averages on a trip.
Symmetry: The property of an
object when the characteristics (size, shape and relative
position of parts) are the same on either side of a dividing
line or about a center.
