Partially Proficient

Students performing at the partially proficient level generally require prompting to demonstrate a basic knowledge of numerical operations, coordinate geometry, functions and relationships and data analysis at a limited level of performance.

In general, partially proficient students:

• Identify square roots with the same radicand
• Determine if two matrices can be added and/or subtracted
• Identify positive and negative slopes
• Identify parallel, perpendicular, and intersecting lines on a coordinate plane
• Identify the direction of a vector
• Locate the minimum and maximum points on a graph of a parabola
• Identify a reflection, dilation, and translation
• Identify different ways to collect data

Proficient

Students performing at the proficient level may require prompting to demonstrate a basic knowledge of numerical operations, coordinate geometry, functions and relationships and data analysis at a moderate level of performance.

In general, proficient students:

• Identify whether radical expressions can be combined using addition and/or subtraction
• Add or subtract two matrices
• Find the midpoint of a line segment on a coordinate plane
• Describe the length and direction of a given vector
• Given a graph of a line, identify the x and y intercepts
• Match the graph of a function to its reflection or translation
• Make predictions using sampling data
• Identify a sample bias in real world situations
