# Interactive video lesson plan for: What are expressions and equations? (Pre-algebra/grade 7 math)

#### Activity overview:

What is an expression? What is an equation? How are those two different? What do we do with each? Learn this and more in this beginning algebra video meant for grade 7 math or pre-algebra.

We also look at how to "translate" verbal descriptions into expressions - the examples I explain are:

"4 times the quotient of n and 3",
"y decreased by 7",
"6 times the quantity x + y", and
"a to the 4th power, multiplied by 5".

The second part of this video lesson is found at https://www.youtube.com/watch?v=97oDTPOuYGU and in it, we look further into how to work with expressions and equations.
