Area of Rectangles and Triangles
Students will calculate the area of rectangles and triangles using appropriate formulas and apply these to problem-solving.
Key Questions
- Predict how changing the base or height affects the area of a triangle.
- Evaluate the accuracy of different methods for finding the area of an irregular shape.
- Explain the relationship between the area of a rectangle and the area of a triangle.

About This Topic
Costume and Mask Design allows 3rd Class students to explore the intersection of art, drama, and identity. By creating wearable art, students move from 2D planning to 3D construction, considering how a piece of art must interact with the human body. This topic covers the use of textiles, found objects, and structural elements to create a character. It aligns with the NCCA Fabric and Fibre and Construction strands, emphasizing 'Visual Awareness' and the ability to communicate a character's traits through visual symbols.
This topic is inherently performative. It encourages students to think about how their artistic choices affect movement and persona. Students grasp this concept faster through role play and simulations where they 'test' their masks or costumes in character, identifying which elements work and which need adjustment.
Active Learning Ideas
Role Play: Character Walk
Students put on their (unfinished) masks or costume pieces and move across the room as their character. Their partner observes and gives feedback on how the costume changes the way they move.
Inquiry Circle: The Attachment Challenge
In small groups, students brainstorm the best way to attach a heavy 'horn' or 'ear' to a mask so it doesn't flop over. They test different methods (tabs, extra card, wire) and share the most stable solution.
Think-Pair-Share: Color and Character
Students choose a character from an Irish legend (e.g., Cú Chulainn). They discuss in pairs which colors and textures (e.g., 'rough' for a warrior, 'shiny' for a magical being) would best represent them.
Watch Out for These Misconceptions
Common MisconceptionA mask only needs to look good from the front.
What to Teach Instead
Students often forget that a mask is a 3D object. Peer observation during the 'Character Walk' helps them see that adding side details or 'depth' makes the character more believable from all angles.
Common MisconceptionYou can just use a single string to hold a heavy mask on.
What to Teach Instead
Many masks fall off or slip. Hands-on 'fitting sessions' allow students to discover that a 'T-shape' strap (one over the top of the head) is much more stable than a single horizontal one.
