Fractions: Introduction to Quantity

In the next few lessons the child is introduced to halves, thirds, fourths, fifths, sixths....tenths and sixteenths using the fraction circles, squares and triangles.

Ten Circles divided into equal parts from one through ten.
A series of four squares divided into equal parts of halves, fourths, eights, and sixteenths.
A series of three triangles divided into equal parts of halves, thirds, and fourths.

One circle, one square, and one triangle are one unit.
We can divided these into two equal parts. These units have been divided into halves.

Fractions are units that have been divided into equal parts. At this point the child may match the labels to the fractions.
