Content Source:

 PBS
Type: Interactive/Game

Overview:

Exhibit your knowledge of 2D shapes and search for similar characteristics. This interactive diagram focuses on sorting polygons by common properties and then you select the correct label for each section of the Venn Diagram.

Content Standard(s):
Mathematics
MA2019 (2019)
Grade: 5
23. Explain that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category.

Example: All rectangles have four right angles, and squares have four right angles, so squares are rectangles.
Unpacked Content
Evidence Of Student Attainment:
Students:
Given a variety of two-dimensional figures,
  • Use attributes to classify a shape into categories and subcategories.
  • Use mathematical vocabulary to explain that attributes belonging to one category are also attributes of the subcategory.
Teacher Vocabulary:
  • Attribute
  • Category
  • Subset
  • Subcategory
  • Two-dimensional
  • Figure
  • Quadrilateral
  • Right angle
  • Parallel
  • Perpendicular
Knowledge:
Students know:
  • vocabulary associated with the properties of shapes.
Skills:
Students are able to:
  • Explain the relationship between shapes in categories and subcategories.
Understanding:
Students understand that:
  • Quadrilaterals can be identified by general properties to more specific properties.
  • Properties belonging to a category of two-dimensional figures also belong to all subcategories of that category.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.5.23.1: Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals).
M.5.23.2: Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
M.5.23.3: Recognize attributes of shapes.
M.5.23.4: Recall the vocabulary of shapes (labels, sides, faces, vertices, etc.).
M.5.23.5: Sort shapes into categories.

Prior Knowledge Skills:
  • Classify triangles according to side measures and angle measures.
  • Classify quadrilaterals based on properties.
  • Explain the relationship between shapes in categories and subcategories.
