                      3rd Grade Math Rap


                      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
                      Break down the GEOMETRY

                      3 sides makes triangle
                      4 sides = quadrilateral
                      5 pentagon, 6 hexagon
                      8 octagon, 10 decagon

                      Lines that never cross - PARALLEL
                      Lines that meet or cross - INTERSECTING
                      Lines that form right angles -- PERPENDICULAR

                      Same shape, same size -- CONGRUENT
                      Line that cuts in half - SYMMETRY
                      Up and Down - VERTICAL
                      Left to Right -- HORIZONTAL

                      An angle less than right - ACUTE
                      An angle opened wide - OBTUSE
                      Ninety degrees square corner - RIGHT ANGLE

                      Back to triangles
                      3 sides the same = equilateral
                      2 sides the same = isosceles
                      no sides the same = Hey, that's a scalene right!

                      So, that's it.
                      That's our math song.
                      Before we leave,
                      Remember to read
                      Your math problems three times before you answer.
                      That way you know what the problem
                      Is asking you to do.
                      Don't be lazy, be brilliant.
                      Piece! Like a fraction.
