Strand: MEASUREMENT AND DATA (4.MD)

Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit (Standards 4.MD.12). Apply knowledge of area and perimeter to solve realworld and mathematical problems (Standard 4.MD.3). Represent and interpret data through the use of a line plot (Standard 4.MD.4). Understand various concepts of angles and angle measurement (Standard 4.MD.57).

Standard 4.MD.5

Recognize angles as geometric figures that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement.

  • Angles (elementary)
    This lesson is designed to help students learn about classifying angles by their measure.
  • Finding an Unknown Angle
    The purpose of this task is to give 4th grade students a problem involving an unknown quantity that has a clear visual representation. Students must understand that the four interior angles of a rectangle are all right angles and that right angles have a measure of 90∘ and that angle measure is additive.
  • Grade 4 Mathematics Module 4: Angle Measure and Plane Figures
    This 20-day module introduces points, lines, line segments, rays, and angles, as well as the relationships between them. Students construct, recognize, and define these geometric objects before using their new knowledge and understanding to classify figures and solve problems. With angle measure playing a key role in their work throughout the module, students learn how to create and measure angles, as well as create and solve equations to find unknown angle measures. In these problems, where the unknown angle is represented by a letter, students explore both measuring the unknown angle with a protractor and reasoning through the solving of an equation. Through decomposition and composition activities as well as an exploration of symmetry, students recognize specific attributes present in two-dimensional figures. They further develop their understanding of these attributes as they classify two-dimensional figures based on them.
  • Grade 4 Unit 7: Measurement (Georgia Standards)
    In this unit students will investigate what it means to measure length, weight, liquid volume, time, and angles, understand how to use standardized tools to measure length, weight, liquid volume, time, and angles, understand how different units within a system (customary and metric) are related to each other, know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz; L, ml; hr, min, sec. and solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals.
  • Measurement and Data (4.MD) - Fourth Grade Core Guide
    The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Fourth Grade Mathematics - Measurement and Data (4.MD)
  • Measuring Angles
    The purpose of this task is to gain experience drawing and measuring angles, developing an understanding of the additive structure of angles.
