Rounding to the Nearest 10 and 100
Students will learn and apply rules for rounding two and three-digit numbers to the nearest ten and hundred.
Key Questions
- Justify why we round 47 to 50 but 43 to 40.
- Compare rounding to the nearest ten versus rounding to the nearest hundred.
- Predict how rounding a number might affect the accuracy of an answer.

About This Topic
Portraiture and Identity allows students to explore the complex relationship between their physical appearance and their inner selves. In the 3rd Year NCCA framework, this topic bridges the gap between technical skill and personal expression. Students learn the basic proportions of the human face while also considering how symbols, colors, and backgrounds can tell a story about who they are. This is a sensitive area where students can reflect on their heritage, hobbies, and aspirations.
By looking at portraits from Irish history and contemporary artists, students see how identity has been portrayed over time. This topic encourages empathy and self-reflection, helping students to appreciate the diversity within their own classroom. The process of creating a self-portrait is deeply personal, but it benefits immensely from collaborative environments. This topic comes alive when students can physically model expressions for one another or engage in structured dialogue about the symbols that represent them.
Active Learning Ideas
Role Play: The Artist and the Muse
Students work in pairs, taking turns to be the 'model' and the 'artist'. The model chooses an emotion to portray through facial expression and posture, while the artist tries to capture that specific mood in a quick sketch.
Think-Pair-Share: Symbolic Self
Students list three objects or colors that represent their personality. They share these with a partner to explain the meaning behind them, then brainstorm how to incorporate these elements into a portrait background.
Gallery Walk: Identity Uncovered
Students display their finished portraits without names. The class moves around the room, trying to match the portrait to the student based on the symbols and personality traits depicted in the artwork.
Watch Out for These Misconceptions
Common MisconceptionThe eyes are at the very top of the head.
What to Teach Instead
Students often forget about the forehead and hair. Using a hands-on measuring activity with their own faces helps them realize that eyes are actually located roughly in the middle of the head.
Common MisconceptionA portrait must look exactly like a photograph to be good.
What to Teach Instead
Many students feel their work is a failure if it isn't hyper-realistic. Analyzing expressive portraits by artists like Louis le Brocquy helps them understand that capturing a 'feeling' is often more important than a literal likeness.
