Clarifications
Clarification 1: Addition and subtraction problems are limited to whole numbers with sums within 100 and related differences.Clarification 2: Data displays can be represented both horizontally and vertically. Scales on graphs are limited to ones, fives or tens.

Purpose and Instructional Strategies
The purpose of this benchmark is to extend the work of grade 1 to interpretation of various data representations and solving problems involving addition and subtraction.- Instruction includes questions that focus on the context of the situation.
- Instruction includes the idea that a picture can represent a single piece of data or a fixed amount.
- Interpretation of data includes both factual and reasoning-based questions.
Common Misconceptions or Errors
- Students may miscount the number of pictures in a pictograph graph or misread the height of a bar in a bar graph.
- Students may think that one picture of an item in a pictograph represents only one item.
Strategies to Support Tiered Instruction
- Teacher provides a pictograph and reads accompanying questions with students, checking for understanding along the way. The teacher focuses on students accurately counting the items in each category, paying special attention to the scale while ensuring that students are utilizing addition and subtraction strategies to accurately respond to each question. Teacher reviews related vocabulary such as fewer, more, in total, and less. Additionally, the teacher aids in accurately counting the items in each category, especially on graphs or tables that require skip counting by 2s or 5s. Ensure students are utilizing addition and subtraction strategies to accurately respond to each question.
- Example:
- Part A. How many astronauts does one astronaut represent? (Point to the scale if student is unsure.)
- Part B. In what grades did fewer than 20 students want to be astronauts?
- Part C. In what grades did at least 5 students want to be an astronaut?
- Part D. How many students wanted to be an astronaut in First grade and Fourth grade? (Aid student in skip counting 5, 10, 15, 20, 25, 30, 35, 40.)
- Part E. How many more students wanted to be an astronaut in kindergarten than in first grade? (Review “more” with students in this context and provide the sentence equation frame _____ − _____ = _____ to aid them if needed.)
- Teacher provides a bar graph and accompanying questions, reading each question, and checking for understanding along the way. The teacher focuses on accurately reading the height of each bar in the bar graph, paying special attention to the scale and ensuring students are utilizing addition and subtraction strategies to accurately respond to each question.
- Example:
- Part A. On which night did Timmy read for 35 minutes?
- Part B. How many more minutes did Timmy read on Tuesday and Friday than on Monday?
- Part C. On which nights did Timmy read more than 20 minutes?
- Part D. On which night did Timmy read fewer than 35 minutes, but more than 15 minutes?
- Part E. If Timmy read for 30 minutes on Saturday night, what would the bar look like?
Instructional Tasks
Instructional Task 1 (MTR.7.1)
A grade 2 class is collecting books to donate. They graph the number of books collected in a pictograph below.- Part A. If the goal was to collect at least 20 books, by how many books did the class exceed their goal?
- Part B. On which days did the class collect at least 6 books?
Instructional Items
Instructional Item 1
A group of students were surveyed about what sport they prefer to play. According to the data on the table below, how many more children prefer to play soccer and tennis compared to the number of children who prefer to play basketball?*The strategies, tasks and items included in the B1G-M are examples and should not be considered comprehensive.

STEM Lessons - Model Eliciting Activity
Collaboration is key! In this MEA lesson, students will have the opportunity to work in collaborative groups to decide what items to include inside a guest goodie bag. The students will be able to interpret data from a table chart, create a bar graph, present their decisions orally in teams, and write an extension letter.
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 process. 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.

Students will research the effects of sugary drinks on their health. They will interpret data on a variety of beverages presented in the form of bar graphs and decide which beverages should be included in school vending machines to ensure students have healthy drink options.
This Model Eliciting Activity (MEA) is written at a 2nd grade level. In this MEA students need to help the owner of Video Game City help his customers decide which gaming system best meets their needs. Students can consider the cost of each gaming system in their rankings. In part 2, students will need to add the cost of each gaming system and accessory.
