The Power of Ten: Grouping
Exploring how numbers are built using groups of ten and leftover units.
Key Questions
- Explain why it is easier to count objects when we group them in tens.
- Analyze how the digit 1 changes its meaning when it moves from the units place to the tens place.
- Predict what happens to a number if we have more than nine units.
NCCA Curriculum Specifications
About This Topic
Self-portraiture in the first year is less about photographic accuracy and more about observation and identity. Students use mirrors to look closely at themselves, identifying the shapes and lines that make them unique. This aligns with the NCCA's 'Looking and Responding' strand, as students must analyze their own features before translating them to the page. It is a powerful exercise in self-awareness and confidence.
Through this process, students learn that everyone sees themselves differently. They explore how features like the curve of a smile or the shape of eyes can be represented through simple artistic marks. This topic is deeply personal and benefits from a supportive, student-centered environment where children can share their work and celebrate the diversity of their classroom community. Students grasp the concept of proportion and detail faster through structured peer observation and discussion about what makes each face special.
Active Learning Ideas
Peer Teaching: The Mirror Challenge
In pairs, one student acts as the 'mirror' and describes a specific feature of their partner (e.g., 'Your eyes are like almonds'). The partner then tries to draw that feature based on the description before checking a real mirror.
Gallery Walk: Identity Wall
Students create self-portraits that include symbols of things they love. They display them around the room, and the class moves from piece to piece, trying to guess whose portrait it is based on the artistic clues and features.
Think-Pair-Share: Changing Faces
Students make different expressions in a mirror (happy, surprised, sleepy). They discuss with a partner how their features change (e.g., 'My eyebrows go up when I'm surprised') and then choose one 'mood' to draw.
Watch Out for These Misconceptions
Common MisconceptionEyes are at the very top of the head.
What to Teach Instead
Students often forget the forehead. Using a simple 'hands-on' measurement (placing hands on chin and top of head) helps them realize eyes are actually in the middle of the face.
Common MisconceptionA self-portrait must look exactly like a photo.
What to Teach Instead
Emphasize that a portrait can show how you feel or what you like. Showing examples of abstract portraits helps students feel comfortable with their own unique drawing style.
