Introduction to Percents
We have been using manipulatives in class to see
percents in concrete form.
A cube equals one hundredth.
A flat equals one whole.

A slice equals one thousandth.
A rod equals one tenth.
2
What percents do these models represent?
0.2 or 20
0.14 or 14
3
Now, we are ready to take percents to an abstract
level. We cannot get an abstract idea just by
looking at a model. We must add some
thought. Abstract ideas are not Right There.
4
Think of the word beauty.Beauty is an abstract
idea.
What comes to your mind?
5
You might think of your favorite beach.
6
or, a flower blooming after a spring rain.
7
But, you cannot imagine beauty without thinking
about something.
Beauty is an idea that applies to things we see.
8
The same thing is true about the word percent.
Percent is an idea that applies to things
that can be counted.
