Elementary Math
Elementary math
includes number theory, which is the study of whole numbers and
relations between them. This unit includes indepth instruction
on factors, multiples, primes, composites, divisibility tests,
and exponents. Try our elementary math lessons below, or

Elementary Math 
Description 
Factors and
GCF 
To define factor
and greatest common factor. To find all factors of a whole number. To find the GCF of two or more whole
numbers. 
Multiples and
LCM 
To define multiple
and least common multiple. To find multiples of whole numbers. To find the LCM of two or more whole
numbers. 
Prime
and Composite
Numbers 
To
define primes and composites. To determine if a
whole number is prime or
composite by examining its factors. 
Divisibility Tests 
To determine if
larger whole numbers are prime or composite by using divisibility
tests for 2, 3, 4, 5, 6, 9 and 10. 
Exponents 
To define
exponent, base and power. To learn exponential notation. To read
and write numbers in exponential form. To convert between standard, factor
and exponential form. 
Patterns and Exponents 
To recognize
patterns with exponents. To predict the next term in
a sequence of numbers written in exponential form.
