Angles in Quadrilaterals
Students will investigate the sum of angles in quadrilaterals and other polygons.
Key Questions
- Explain the relationship between the number of sides of a polygon and the sum of its interior angles.
- Analyze how the properties of specific quadrilaterals (e.g., square, rectangle, parallelogram) affect their angles.
- Construct a method to find a missing angle in a quadrilateral.

About This Topic
Found Object Assemblage encourages 6th Class students to see the artistic potential in everyday items. Instead of starting with traditional materials like paint or clay, students collect and combine 'junk', bottle caps, old toys, cardboard, or natural items, to create a new, unified sculpture. This aligns with the NCCA Construction strand and promotes environmental awareness through the concept of 'upcycling.'
This topic is about metaphor and storytelling. Students must think about how the history of an object (like a rusted key or a broken watch) adds meaning to their artwork. It connects to the 'Looking and Responding' strand as students analyze how contemporary artists use found objects to comment on consumerism or nature. This topic thrives on collaborative 'sorting' sessions where students categorize objects by shape, color, or texture before beginning their construction.
Active Learning Ideas
Inquiry Circle: The Object Sort
The class brings in bags of 'clean junk.' In small groups, they must sort these items into categories: 'Industrial,' 'Organic,' 'Transparent,' or 'Geometric.' This helps them see objects as 'shapes and textures' rather than just 'trash.'
Think-Pair-Share: The Story of the Thing
Each student picks one interesting object. They have two minutes to tell a partner a fictional 'history' of that object. This encourages them to think about the narrative potential of their materials before they start gluing things together.
Stations Rotation: Joining Challenges
Set up stations with different adhesives: hot glue (with supervision), wire ties, masking tape, and string. Students must try to join two 'difficult' objects (like a plastic bottle and a metal spoon) at each station to see which method is most secure.
Watch Out for These Misconceptions
Common MisconceptionStudents often think they should just glue everything together randomly.
What to Teach Instead
This leads to a cluttered look. By using a 'gallery walk' of half-finished works, students can discuss 'composition' and 'focal points,' learning that leaving some space or grouping similar objects makes the sculpture more powerful.
Common MisconceptionBelieving that the objects must still look like what they originally were.
What to Teach Instead
The goal of assemblage is often 'transformation.' Encouraging students to paint the entire finished sculpture a single color (like all white or all bronze) helps them see the new form they've created rather than just a pile of separate items.
