Dividing by Fractions, An Animation, Partition Division

Description:

I added captions!

The video is an animated explanation of dividing by fractions.  This article was the inspiration: Making Sense of Partitive and Quotitive Division: A Snapshot of Teachers’ Pedagogical Content Knowledge by Anne Roche, Australian Catholic University,  and Doug Clarke, Australian Catholic University, . Teachers and students understand 8 / 2. But 8 / (.5) can be more difficult.

The process of dividing 8 by 2 is partition division. Dividing 8 by 0.5 is best done with partition division.

What is division?
Reference 
Wikipedia  and Mathematics Stack Exchange


Division can written as: a/b = c.
a is the dividend.
b is the divisor.
c is the quotient.

Division can be expressed as:
1) Partition division
2) Quotition division


Partition Division

6 / 2 = ?
Divide 6 into 2 groups.
How many are in each group?

(Get the answer! Show 6 tiles. Make 2 equal groups. Count how many there are in a group.)

6/2 = 3

Quotition Division

6/2 = ?

Divide 6 into groups of 2.
How many groups are there?

(Get the answer! Show 6 tiles. Make groups of 2 tiles. Count how many groups.)

6/2 = 3
