Chapter+4

Chapter 4.1

 * ==determine whether one number is a factor of another==
 * ==determine whether an expression is a monomial==

Here is a website that lists the different factors from the number 1 up to number 1,100 (this also might help you with seeing prime and composite numbers.) @http://factorzone.tripod.com/factors.htm

A hard mind-boggaling game about factors. To win you have to find the factors of a number choosen by your openent (could be computer or another player).Hint: Try to find all of the factors for more points. You can do different difficulties Easy: starts with 1 and goes up to 30. Medium: 1-49 and Hard: 1-100. @http://illuminations.nctm.org/activitydetail.aspx?id=12

This shows the defination of monomials and examples: @http://www.icoachmath.com/math_dictionary/monomial.html

Chapter 4.2

 * ==write expressions using exponents==
 * ==evaluate expressions containing exponents==



Chapter 4.3
Prime factorization game!! Different kinds to play by: 1. finding the prime factorization of one number and 2. Finding the prime factorization of 2 numbers.
 * ==write the prime factorizations of composite numbers==
 * ==factor monomials==

@http://www.mathplayground.com/factortrees.html This has some info on prime factorization of monomials: @http://hotmath.com/hotmath_help/topics/factoring-monomials.html

Chapter 4.4
You need to scroll down a little to find the GCF part, but its good and it shows examples with a lot of info:
 * ==find the greatest common factor of two or more numbers or monomials==
 * ==use the distributive property to factor algebraic expressions==

Chapter 4.5

 * ==simplify fractions using GCF==
 * ==simplify algebraic fractions==

Chapter 4.6

 * ==multiply monomials==
 * ==divide monomials==

Chapter 4.7

 * ==write expressions using negative exponents==
 * ==evaluate numerical expressions containing negative exponents==

Chapter 4.8
This is a good video with some good notes. Listen carefully and add to your notes! []
 * ==express numbers in standard form and in scientific notation==
 * ==compare and order numbers written in scientific notation==

I like brightstorm videos, here's one on scientific notation. []

These notes actually come from a college class, but I thought they broke things out nicely into steps... []

Comparing numbers This is a good video, but you have to get through the advertisements... []

More advertisements, otherwise good too! []
