Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

Learning Targets (I can)
Describe two-dimensional figures by their attributes (i.e. number of sides, angles, length of sides, parallel and perpendicular lines).
Compare two-dimensional figures by their attributes.
Classify two-dimensional figures by their attributes.
Describe how two-dimensional figures can belong to several subcategories according to their attributes.
Identify subcategories using two-dimensional attributes.
About the Math
We classify figures by their attributes. 2 figures may share similar attributes but also have different attributes. These similarities and differences allow us to group figures as subsets of others. For example, rectangles and squares are both quadrilaterals. All squares are rectangles because they are 4 90° vertices. However, all rectangles are not squares because some of them have a set of opposite sides that are not equal to the other set.

These tasks can be used with small group or whole group instruction.
Can you draw a shape that has no lines of symmetry, exactly two right angles and one acute angle?
What is the definition of a parallelogram? Does a square fit in that category?
Draw two quadrilaterals, compare their angles, sides, lines or symmetry etc.
How many other classifications does a square fit? (A square is a parallelogram, and a rhombus, and a rectangle.)
SLIDE-BASED TASKS
These links are HCPSS created instructional tasks. These tasks are provided in Google slides. When selected, a copy of the file is added to your drive for classroom use.These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first(often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
These publications have been provided for each school. They are typically stored in team closets or the media center. Check with your team leader if you cannot find them.
These resource sheets can be used for independent practice, homework, or assessment. They are intended to reinforce procedures and concepts. They should not be used as a source of direct instruction or whole-group practice.
