To assist teachers with understanding their students’ *aMath* scores, this interpretation guide organizes score information by score ranges, skill categories, and skill descriptions with accompanying instructional recommendations. In the online reports and in this Guide, all score ranges include skill information for one or more of the following categories:

*Counting & Cardinality*: Know the number names and the counting sequence*Operations & Algebraic Thinking*: Understand the principles of, and facts for, addition, subtraction, multiplication, and division*Number & Operations in Base Ten*: Work with numbers in relation to their base ten values to solve problems*Number & Operations—Fractions*: Work with fractions and mixed numbers to solve problems*Measurement & Data*: Classify, describe, measure, and analyze different types of data*Geometry*: Identifying, describing, analyzing, comparing, and measuring different shapes*Ratios & Proportional Relationships*: Understand ratio concepts and use ratio reasoning to solve problems*The Number System*: Under and use rational and non-rational numbers*Expressions & Equations*: Solve real-life and mathematical problems using linear and non-linear equations with numerical and algebraic expressions.*Functions*: Use a variety of functions to model relationships between and among quantities*Statistics & Probability*: Use statistical data to interpret categorical and quantitative data, make inferences and justify conclusions, and apply probability rules to make decisions

**Understanding aMath Scores: Individual Skills Report**

The FastBridge Report that provides the most detail about which specific skills a student needs to improve is the Individual Skills Report. For aMath, this report displays a student's skills to indicate three levels of learning:

**Mastered**: Skills that the student knows well and can use independently.**Developing**: Skills that the student needs to work on now.**Future**: Skills to learn once the developing skills are mastered.

FastBridge recommends that teachers focus on teaching and supporting students to master the Developing Skills for each of the CCSS categories.

**aMath Score Interpretation Guide**

The attached Score Guide lists the *aMath* scores according to bands of 50 points, starting at 145 and ending at 275. Each score band lists the skill categories included, descriptions of the skills, and instructional recommendations to teach each skill.
