FRACTIONS
Learning and understanding is the key!

NCSCS 1.05Use models of fractions to explore
part-whole relationships.
  • 1.05 a Represent fractions concretely and
    symbolically (halves, fourths, thirds, sixths and
    eighths.)
  • 1.05 b compare and order fractions
  • 1.05 c model and describe common equivalent
    fractions

3
Fractions have EQUAL parts!There is no such
thing as the biggest half!!!
Hey! You got the biggest half!!!
4
Remember the numbers have names!
  • numerator
  • denominator

5
DENOMINATORS
tell how many pieces the whole is divided into.
The 2 means the whole is divided into 2 equal
parts.

DENOMINATORS
also tell how many parts are needed to make up
the whole.

Check this out!
Did you realize the larger the number in the
denominator

the smaller the fractional part! One half of this
rectangle

is much larger than one eighth!

Lets take an even closer look!
Some fractions have different denominators but
are still exactly equal!
