Achievement Descriptors: Overview
Part 1: Place Value Concepts Through Metric Measurement and Data
Achievement Descriptors (ADs) are standards-aligned descriptions that detail what students should know and be able to do based on the instruction. ADs are written by using portions of various standards to form a clear, concise description of the work covered in each module. Each module has its own set of ADs, and the number of ADs varies by module. Taken together, the sets of module-level ADs describe what students should accomplish by the end of the year.
ADs and their proficiency indicators support teachers with interpreting student work on
• informal classroom observations (recording sheet provided in the module resources),
• data from other lesson-embedded formative assessments,
• Exit Tickets,
• Topic Tickets, and
• Module Assessments.
This module contains the nine ADs listed.
2.Mod1.AD1
Measure lengths of objects by using metric units (centimeters and meters).
Estimate lengths of objects by using metric units (centimeters and meters).
2.Mod1.AD3
Measure and find a difference in length by using metric units (centimeters and meters).
2.Mod1.AD4
Add or subtract within 100 to solve word problems involving length by using drawings and equations.
2.MD.B.5
2.Mod1.AD5
Represent whole numbers within 100 on a number line.
2.Mod1.AD6
Represent sums within 100 by using a number line.
2.Mod1.AD7
Represent differences within 100 by using a number line.
2.MD.B.6
2.Mod1.AD8
Draw and label picture and bar graphs to represent a data set with up to four categories.
2.Mod1.AD9
Solve addition, subtraction, and comparison problems by using information from a bar graph.
The first page of each lesson identifies the ADs aligned with that lesson. Each AD may have up to three indicators, each aligned to a proficiency category (i.e., Partially Proficient, Proficient, Highly Proficient). While every AD has an indicator to describe Proficient performance, only select ADs have an indicator for Partially Proficient and/or Highly Proficient performance.
An example of one of these ADs, along with its proficiency indicators, is shown here for reference. The complete set of this module’s ADs with proficiency indicators can be found in the Achievement Descriptors: Proficiency Indicators resource.
• AD Code: The code indicates the grade level and the module number and then lists the ADs in no particular order. For example, the first AD for grade 2 module 1 part 1 is coded as 2.Mod1.AD1.
• AD Language: The language is crafted from standards and concisely describes what will be assessed.
• AD Indicators: The indicators describe the precise expectations of the AD for the given proficiency category.
• Related Standard: This identifies the standard or parts of standards from the Common Core State Standards that the AD addresses.

2.MD.A.1 Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
Partially Proficient Proficient
Measure lengths of objects by using metric units (centimeters and meters) for objects that are easily measured with a ruler (e.g., flat and straight).
Measure the pencil with a 10 cm ruler.
The pencil is cm long.
Related Standard
Measure lengths of objects by using metric units (centimeters and meters) for objects that require choosing an appropriate tool before measuring.
Circle the best tool to measure the length around a ball.
10 cm ruler meter stick measuring tape
Use the tool to measure the length around a ball.
2.Mod1.AD2 Estimate lengths of objects by using metric units (centimeters and meters).
