To enhance their skills in each mathematics-related strand, students who score in the 20–23 score range may benefit from activities that encourage them to do the following:
Score Range 20–23
| Basic Operations & Applications |
- apply and use number properties to model and solve problems that involve reasoning with proportions
- select and use appropriate units when solving problems that involve one or more units of measure
|
| Probability, Statistics, & Data Analysis |
- construct and analyze Venn diagrams to help determine simple probabilities
|
| Numbers: Concepts & Properties |
- use the inverse relationships for the four basic operations, exponentiation, and root extractions to determine unknown quantities
- perform basic operations with complex numbers†
|
| Expressions, Equations, & Inequalities |
- identify, interpret, and generate symbolic representations that model the context of a problem
- factor and perform the basic operations on polynomials
- create and solve linear equations and inequalities that model real-world situations
- solve literal equations for any variable
|
| Graphical Representations |
- represent and interpret relationships defined by equations and formulas; translate between representations as ordered pairs, graphs, and equations; and investigate symmetry and transformations (e.g., reflections, translations, rotations)
|
| Properties of Plane Figures |
- recognize what geometric properties and relationships for parallel lines
to apply to find unknown angle measures
- recognize when to apply geometric properties and relationships of triangles to find unknown angle measures
|
| Measurement |
- apply a variety of strategies to determine the circumference or perimeter and the area for circles, triangles, rectangles, and composite geometric figures
|
| Functions† |
- identify the basic trigonometric ratios†
