                                  By McCarthy Math Academy

                                  With a little help from the group, Mindless Behavior, I have created a math video with lyrics to help my students to understand and apply core math skills for third grade. People of all ages can jam out to this one. Enjoy!

                                  I've got a case of the operation blues.
                                  Because I don't know which one I should use.
                                  Look at the word problem for the clues.
                                  The key words tell you how to choose.

                                  Each means you multiply or you must divide.
                                  Tryna find the total? Then you multiply
                                  Total's in the problem? Then you must divide.
                                  Not quick to solve it, draw it, get it right.

                                  Addition's easy for me and you
                                  Sum, In all, together, and total too.
                                  When do you subtract? How many more?
                                  Fewer? Left? Less? Difference in a score?

                                  Place value's next. Disco on the " dess "
                                  Ones, tens, hundreds, to the left
                                  Thousands, Ten thousands, hundred...thousand
                                  Say the name of the place, yeah.

                                  The value's the amount of the place
                                  For example, 2,060.
                                  The value of the 2 is 2-0-0-0,
                                  The value of the 6 is 6-0.

                                  When you round, find and underline the place
                                  Spotlight to the right, decide the digit's fate
                                  5 or more, add 1 to the rounding place
                                  4 or less, do nothing but walk away, (estimate)

                                  A pen, penny is one, one cent
                                  A Nic-kel is five, a dime is ten cents
                                  25 for a quarter, George Washington
                                  100 cents makes a dollar, there he goes again.

                                  For pictographs, you gotta check out the key
                                  One smiley face might really equal three
                                  For bar graphs, pay attention to the scale
                                  Think it's counting by ones, huh, you'll fail

                                  Fractions are easy, just draw your best.
                                  Here they go from least to greatest
                                  1/12, 1/6, ¼, 1/3,
                                  ½, 2/3, ¾, Fraction nerd!

                                  You see that number on top,
                                  That's called the numerator
                                  It describes the amount
                                  That is being considered
                                  And if you jump down from the fraction bar
                                  Denominator
                                  It's the total number of equal parts.

                                  Let me give you an example:
                                  Leslie Moin has some coins
                                  A total of 9
                                  2 happen to be pennies
                                  While 7 are dimes.
                                  What's the fraction of dimes?
                                  How many coins? 9
                                  How many dimes? 7
                                  Say the fraction -- seven ninths

                                  Length times width is Area
                                  Distance around is Perimeter

                                          By Mr. McLogan's Math Channel

                                          In this video tutorial I will show you how to find the inverse of a function f(x). I do this by first writing the equation substituting y for f(x). I then solve the equation for x. The result is the inverse. The inverse can be written, substituting y back in for x, and x for y. I also show how to verify that a function is an inverse of another function. I am a math teacher that provides free online math tutoring by working through problems for the website www.freemathvideos.com These questions are usually to help students understand their math homework or to do well on their math test. The videos are made for students that want help with math and want to be shown a step by step process into solving the problems. In addition to solving the problems I also offer explanations into why I am doing each step. I offer free math videos so that my students can learn math online if they missed a day of school. However I also like to answer questions that are no

But it's the key to opportunity for our citizens, economic vitality for our nation, and to assuring the U.S. remains a world leader. There is hope: innovations and innovators that challenge the status quo; research to help us understand how to move the education needle; a virtual army of reformers experimenting with new ways to teach, learn, and run our public schools.
