NFS Curriculum Update :: April, 2015
Eighth graders are wrapping up the polynomials unit factoring with a lead coefficient greater than one and factoring terms by grouping. Students will then switch gears and simplify radical expressions and perform operations using the multiplication and division properties of square roots in addition to recognizing that a single quantity can be represented in many different expressions. Following ERB testing, investigators will examine quadratic functions by identifying the vertex, calculating the axis of symmetry, and comparing the transformations to its parent function.
Eighth graders will continue simplifying radical expressions and will examine the domain of radical functions and check for extraneous solutions. Analysts will graph inverse and radical functions, adding two new functions to their repertoire. Next, mathematicians will dissect the components of quadratic functions by identifying the vertex, line of symmetry, maximum or minimum, domain, range, and translations from the parent function. Students will also calculate the roots of the function by graphing, completing the square, and the quadratic formula.
