Fractions


Identify the NU MER A TOR and DE NO MI NA TOR

http://www.learningupgrade.com/mathup/index.htm

Lyrics to the song

We had one whole delicious apple pie
And 5 hungry people to share that pie
We divided that pie into
5 EQUAL slices
(ya ma, 5 slices)



My share was one slice of that pie
Of the 5 equal slices of the whole pie
I got ONE-FIFTH (1/5) of that pie
And that’s a FRACTION!
A PROPER FRACTION

A fraction has a DE-NO-MI-NA-TOR that goes below the line
Shows how many slices the whole pie has (Five!)
A fraction has a NU-MER-A-TOR that goes above the line
Shows how many slices I have (One!)
(Watch me now)

When the NUMERATOR is greater than the DENOMINATOR
That is what we call an
IMPROPER FRACTION
(thirteen over four)13/4

Sometimes we have a whole number
Together with a fraction
A whole number and a fraction – a… a MIXED NUMBER…..
Three and one-fourth
And that’s a FRACTION!!!!..... (ya!)
