# If-then statements

Valid statements can be used to build logical arguments.

'If-then' is a common form of argument. In senior mathematics classes, the notation used for this argument is $$p \rightarrow q$$. You can read more about this notation and watch a video from the Math Planet website at http://www.mathplanet.com/education/geometry/proof/if-then-statement.

However, much younger students should learn this form of argument.

A typical if-then problem and variations on it make a good starting point. You can download Insects and Spiders: An Avenue for If-then Thinking.
