What is a Fraction

A fraction is a part of a whole.

Lets a say we cut a whole apple in to 2 pieces.

We will get two halves (1/2) .  Now if we cut it again, we will have 4 pieces or four quarters (1/4).


The number above the fraction bar is called the numerator.


The number below the fraction bar is called the denominator.


Example of fractions:




Compare Fractions:

Now lets compare fractions.  If we want to compare fractions, we need to draw pictures.

For example, we can take 1/2 and  3/4.

Which is a bigger piece?  We can see that 3/4 is bigger than 1/2. It is bigger because we have 1 more piece.

Pattern Block Fractions:

Please check these shapes below,


1 Hexagon has 2 Trapezoids or 3 rhombuses or 6 triangles.
1 Trapezoid has 1 rhombus and 1triangle or 3 triangles.
1 rhombus has 2 triangles.

Lets write these in fractions:
