## Collection Contents

### Cluster - Interpret the structure of expressions.

by Allen Wolmer

Focus on quadratic and exponential expressions. For A.SSE.1b, exponents are extended from the integer exponents found in Unit 1 to rational exponents focusing on those that represent square or cube roots.

### Cluster - Write expressions in equivalent forms to solve problems.

by Allen Wolmer

It is important to balance conceptual understanding and procedural fluency in work with equivalent expressions. For example, development of skill in factoring and completing the square goes hand-in-hand with understanding what different forms of a quadratic expression reveal.

### Cluster - Perform arithmetic operations on polynomials.

by Allen Wolmer

Focus on polynomial expressions that simplify to forms that are linear or quadratic in a positive integer power of x.

### Cluster - Create equations that describe numbers or relationships.

by Allen Wolmer

Extend work on linear and exponential equations in Unit 1 to quadratic equations. Extend A.CED.4 to formulas involving squared variables.

### Cluster - Solve equations and inequalities in one variable.

by Allen Wolmer

Students should learn of the existence of the complex number system, but will not solve quadratics with complex solutions until Algebra II.

### Cluster - Solve systems of equations.

by Allen Wolmer

Include systems consisting of one linear and one quadratic equation. Include systems that lead to work with fractions. For example, finding the intersections between x^2+y^2=1 and y = (x+1)/2 leads to the point (3/5, 4/5) on the unit circle, corresponding to the Pythagorean triple 3^2+4^2=5^2.
