Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.

Unpacked Content

Knowledge

Students know:

how to add, subtract, multiply, and divide rational numbers.
A(b + c) = ab + ac.
how to find the greatest common factor of two or more terms.

Skills

Students are able to:

apply properties of operations as strategies to add and subtract linear expressions with rational coefficients.
Apply properties of operations as strategies to factor linear expressions with rational coefficients.
Apply properties of operations as strategies to expand linear expressions with rational coefficients.

Understanding

Students understand that:

only like terms can be combined, e.g., x + y = x + y but x + x = 2x.
To factor an expression, one must factor out the greatest common factor.
There are many different ways to write the same expression.
