Strand: MEASUREMENT AND DATA (2.MD)

Measure and estimate lengths in standard units (Standards 2.MD.1-4) and relate addition and subtraction to length (Standards 2.MD.5-6). They work with time and money (Standards 2.MD.7-8). They represent and interpret data (Standards 2.MD.9-10).

Standard 2.MD.10

Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and comparison problems using information presented in a bar graph.

• Bar Graph Sorter
  The objectives of this lesson are to introduce bargraphs and ask students to sort them by a particular attribute.
• Favorite Ice Cream Flavor
  The purpose of this task is for students to represent and interpret categorical data. So this task could be used with advanced first graders or second graders just beginning to work with bar graphs.
• Grade 2 Math Module 7: Problem Solving with Length, Money, and Data (Engage NY)
  Module 7 presents an opportunity for students to practice addition and subtraction strategies within 100 and problem-solving skills as they learn to work with various types of units within the contexts of length, money, and data. Students represent categorical and measurement data using picture graphs, bar graphs, and line plots. They revisit measuring and estimating length from Module 2, though now using both metric and customary units.
• Grade 2 Unit 1: Extending Base Ten Understanding (Georgia Standards)
  In this unit, students will understand the value placed on the digits within a three-digit number, recognize that a hundred is created from ten groups of ten, use skip counting strategies to skip count by 5s, 10s, and 100s within 1,000 and represent numbers to 1,000 by using numbers, number names, and expanded form, compare two-digit number using >, =, <.
• Grade 2 Unit 2: Becoming Fluent with Addition and Subtraction (Georgia Standards)
  In this unit students will cultivate an understanding of how addition and subtraction affect quantities and are related to each other, will reinforce the multiple meanings for addition (combine, join, and count on) and subtraction (take away, remove, count back, and compare), further develop their understanding of the relationships between addition and subtraction, recognize how the digits 0-9 are used in our place value system to create numbers and manipulate amounts and continue to develop their understanding solving problems with money.
• Grade 2 Unit 3: Understanding Measurement, Length, and Time (Georgia Standards)
  In this unit students will know the following customary units for measuring length: inch, foot, yard, recognize the need for standard units of measure, understand the relationship of hours and days and nderstand the importance, usefulness of reasonable estimations and e able to represent the length of several objects by making a line plot.
• Grade 2 Unit 4: Applying Base Ten Understanding (Georgia Standards)
  In this unit students will continue to develop their understanding of and facility with addition and subtraction, add up to 4 two-digit numbers, use a variety of models (base ten blocks- ones, tens, and hundreds only; diagrams; number lines; place value strategies; etc.) to add and subtract within one thousand and continue to develop their understanding of, and facility with, money.
• Grade 2 Unit 5: Understanding Plane and Solid Figures (Georgia Standards)
  In this unit students will cultivate spatial awareness by further developing understandings of basic geometric figures, identifying plane figures and solid figures based on geometric properties, understand what an array is and how it can be used as a model for repeated addition and organize and record data using tallies, simple tables and charts, picture graphs, and bar graphs.
• Grade 2 Unit 6: Developing Multiplication (Georgia Standards)
  In this unit students will understand and model multiplication as repeated addition and as rectangular arrays, determine if a number is odd or even (within twenty) and create and interpret picture graphs and bar graphs.
• Graphing with Colors
  This Teaching Channel video and lesson plan has students find colored squares around the room and then create a bar graph. (4 minutes)
• Growing Bean Plants
  This task adds some rigor to this common activity, by collecting actual growth data, providing practice for students in measuring and recording length measurements.
• Hand Span Measures
  This could be used as a class activity, or students could gather and plot data on separate line plots from different age groups.
• Histogram
  This activity will help students understand histograms by allowing them to make their own.
• Longest Walk
  Given a map, students in this task locate two points and draw a line between them and then calculate the length of the line.
• Measurement and Data (2.MD) - Second Grade Core Guide
  The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Second Grade Mathematics - Measurement and Data (2.MD)
