Strand: GEOMETRY (2.G)

Reason with shapes and their attributes.

Standard 2.G.1

Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Sizes are compared directly or visually, not compared by measuring. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

• Bar Graph Sorter
The objectives of this lesson are to introduce bargraphs and ask students to sort them by a particular attribute.
• 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.
• Polygons
The purpose of this task is to give students practice identifying different types of polygons, namely triangles, quadrilaterals, pentagons, and hexagons.
• Venn Diagram Shape Sorter
This lesson is designed to introduce young students to the concept Venn diagrams and explore different kinds.
