Angles in Triangles
Students will explore the properties of angles within different types of triangles.
Key Questions
- Justify why the sum of angles in any triangle is always 180 degrees.
- Predict the measure of a missing angle in a triangle given two other angles.
- Compare the angle properties of equilateral, isosceles, and scalene triangles.

About This Topic
Wire and Kinetic Sculpture introduce 6th Class students to 'drawing in space.' Instead of using a pencil on paper, they use wire to create three-dimensional lines. This topic also explores 'kinetics', art that moves. This aligns with the NCCA Construction strand, where students are encouraged to use a variety of materials to create form and explore the concept of balance.
This topic is a fantastic bridge to Science and Engineering (STEM). Students must grapple with the center of gravity, use, and structural integrity to make their sculptures stand or move. It also encourages them to think about the 'negative space', the air inside and around the wire. This topic is most effective when students work in pairs to troubleshoot balance issues, using collaborative problem-solving to make their sculptures stable yet dynamic.
Active Learning Ideas
Inquiry Circle: The Balance Challenge
Students are given a single piece of wire and a heavy base (like a block of wood or clay). They must work in pairs to see how far they can make the wire 'lean' without the whole thing toppling over. They discuss how the 'center of gravity' changes as they bend the wire.
Simulation Game: Shadow Drawing
Place a wire sculpture in front of a bright light so it casts a shadow on a large sheet of paper on the wall. Students trace the shadow, then turn the sculpture slightly and trace it again. This shows how a 3D line creates different 2D shapes as it moves.
Peer Teaching: Joining Techniques
Divide the class into groups to master one 'join': the loop, the twist, and the wrap. Each group then acts as 'consultants' for the rest of the class, helping their peers secure their sculptures using the specific technique they learned.
Watch Out for These Misconceptions
Common MisconceptionStudents often think they need to use a lot of wire to make a 'good' sculpture.
What to Teach Instead
In wire art, less is often more. By doing a 'one-line challenge' where they can only use a single meter of wire, students learn to focus on the most important lines of the form rather than creating a tangled mess.
Common MisconceptionBelieving that a sculpture must be perfectly still to be 'finished.'
What to Teach Instead
Kinetic art is meant to move! By introducing the work of Alexander Calder (mobiles), students can see that air currents and balance are part of the art itself. Encouraging them to blow on their work to see how it reacts helps them embrace movement.
