Strand: GEOMETRY (2.G)

Reason with shapes and their attributes.

Standard 2.G.3

Partition circles and rectangles into two, three, or four equal shares; describe the shares using the words halves, thirds, half of, a third of, etc.; and describe the whole as two halves, three thirds, or four fourths. Recognize that equal shares of identical wholes need not have the same shape.

  • Geometry (2.G) - 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 - Geometry (2.G)
  • Grade 2 Math Module 8: Time, Shapes, and Fractions as Equal Parts of Shapes (Engage NY)
    In Module 8, the final module of the year, students extend their understanding of partwhole relationships through the lens of geometry. As students compose and decompose shapes, they begin to develop an understanding of unit fractions as equal parts of a whole.
  • 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.
  • IXL Game: Identify the Fraction
    This game helps second graders reason with shapes and their attributes by identifying the fraction. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use.
  • Single Fraction Pointer
    This activity was designed to help students better understand fractions by practicing dividing a whole into a fraction and visualizing fractions on a number line.
  • Which Pictures Represent One Half?
    The purpose of this task is for students to see different ways of partitioning a figure into two or more equal shares, by which we mean decomposing the figure into "pieces" with equal area.
