MAFS.912.F-LE.2.5 Assessed within F-LE.1.1 MAFS.912.F-BF.1.1 Assessed within F-LE.1.2 MAFS.912.F-BF.2.3 ITEMS SPECIFICATIONS: Item Types Equation Editor – May require creating a value or an expression. GRID – May require plotting points or a transformed function. Matching Item – May require matching an equation, a value of k, and an explanation of the effect on a graph. Multiple Choice – May require selecting a graph or a table from a list. Open Response – May require explaining the effects of a transformation. Table Item – May require completing a table of values. Clarifications Students will determine the value of k when given a graph of the function and its transformation. Students will identify differences and similarities between a function and its transformation. Students will identify a graph of a function given a graph or a table of a transformation and the type of transformation that is represented. Students will graph by applying a given transformation to a function. Students will identify ordered pairs of a transformed graph. Students will complete a table for a transformed function. Assessment Limits Functions represented algebraically are limited to linear, quadratic, or exponential. Functions represented using tables or graphs are not limited to linear, quadratic, or exponential. Content Complexity: Level 2: Basic Application of Skills & Concepts
Clarifications Students will write an equation in one variable that represents a real-world context. Students will write an inequality in one variable that represents a real-world context. Students will solve a linear equation. Students will solve a linear inequality. Students will solve multi-variable formulas or literal equations for a specific variable. Students will formulas and equations with coefficients represented by letters. Assessment Limits In items that require the student to write an equation, equations are limited to exponential functions with one translation, linear functions, or quadratic functions. Items may include equations or inequalities that contain variables on both sides. In items that require the student to write an exponential function given ordered pairs, at least one pair of consecutive values must be given. In items that require the student to write or solve an inequality, variables are restricted to an exponent of one. Items that involve formulas should not include overused contexts such as Fahrenheit/Celsius or three-dimensional geometry formulas. In items that require the student to solve literal equations and formulas, a linear term should be the term of interest. Items should not require more than four procedural steps to isolate the variable of interest. Items may require the student to recognize equivalent expressions but may not require a student to perform an algebraic operation outside the context of Algebra 1. Stimulus Attributes Items assessing A-CED.1.1 and A-CED.1.4 must be placed in real-world context. Items assessing REI.2.3 do not have to be in a real-world context. Response Attributes Items assessing REI.2.3 should not require the student to write the equation. Items may require the student to choose an appropriate level of accuracy. Items may require the student to choose and interpret units. For A-CED.1.1 and A-CED.1.4, items may require the student to apply the basic modeling cycle.
