Remarks
Use of addition, subtraction, multiplication, and division of whole numbers should be included during this process.
At this grade level, students might analyze graphs with words such as most, least, minimum, and maximum to provide a conceptual foundation for the more formal terms such as mode and range that they will learn in later grades.
The collected data and the intent of the data collection should help to determine the choice of data display.
-
Item Type(s):
This benchmark may be assessed using:
MC
item(s)
At Grade 3, this benchmark will be assessed using MC items.
- Clarification :
Students may identify the correct display of a given set of data.
Students will analyze and draw conclusions about data displayed in the form of frequency tables, bar graphs, pictographs, and line plots.
Students will analyze data to supply missing data in frequency tables, bar graphs, pictographs, and line plots. - Content Limits :
Items may require the student to choose the most appropriate datadisplay given a set of data from observations, surveys, and/orexperiments.
Items may assess identifying parts of a correct graph and recognizingthe appropriate scale.
The increments used on the scale are limited to units of 1, 2, 5, 10,50, or 100.
Pictographs can use keys containing a scale of 1, 2, 5, or 10.
The data presented in graphs should represent no more than five categories.
The total sample size for bar graphs should be no more than 1,000.
The total sample size should be no more than 200 for frequencytables, pictographs, and line plots.
Addition, subtraction, or multiplication of whole numbers may beused within the item.
- Stimulus Attributes :
Items may be set in a real-world or mathematical context.
Increment grid lines must be shown on graphs.
Graphics will be used in all items.

STEM Lessons - Model Eliciting Activity
In this Model-Eliciting Activity (MEA), a student engineering team is asked by a wheel manufacturer to investigate and develop a plan to select the best model of roller blades.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

In this Model Eliciting Activity, MEA, students will determine what two snacks should be placed in the school vending machines because the district is asking for healthier and tastier snacks. Factors to consider are calories, fat, protein, sugar, student comments, and cost.
