You do not always need to get permission to use copyrighted works.
U.S. Copyright law provides exemptions for using copyrighted works without permission under certain conditions, such as Fair Use.
There are no absolute rules for what is considered fair use. Copyright law outlines four factors that should be considered when determining fair use. It is up to you to determine how well the use of a work addresses these factors.
To determine fair use, you need to conduct a Fair Use Analysis. This analysis will weigh the four factors of fair use.

Isn't educational use the same as fair use?
Unforturnately, it isn't. Using an item for an educational purpose weighs in favor of fair use for the first factor, but you must consider all four of the factors to make a fair use determination.
Is it always fair use to use 10% or less of a work?
No. Copyright law does not provide a percentage that would constitute fair use. Generally, the smaller the amount used, the more likely it is that the use is fair. However, the other factors must also be considered.
