Subtraction with Regrouping (3-digit)
Students will practice subtraction of three-digit numbers, including multiple regroupings, using the standard algorithm.
Key Questions
- Analyze the steps involved in regrouping across zeros in subtraction.
- Explain how we can prove our subtraction is correct using addition.
- Compare different methods for subtraction and evaluate their efficiency.

About This Topic
Landscape and Perspective introduces 3rd Year students to the magic of creating space on a flat surface. This topic aligns with the NCCA's focus on 'Looking and Responding' to the environment. Students explore the Irish landscape, from the rugged Atlantic coast to the rolling hills of the midlands, and learn how to translate these vistas into art. They study how objects appear smaller, less detailed, and 'cooler' in color as they recede into the distance.
Key concepts include the horizon line, vanishing points, and the division of the page into foreground, middle ground, and background. This isn't just a technical exercise; it's about making choices as an artist to lead the viewer's eye through a scene. This topic comes alive when students can physically model the patterns of perspective using outdoor sketching or collaborative 3D models.
Active Learning Ideas
Inquiry Circle: The Window View
Students work in groups to look out different school windows. They use dry-erase markers to trace the main 'lines' of the landscape directly onto the glass, helping them see how 3D space flattens into 2D shapes.
Gallery Walk: Depth Detectives
Display various landscape paintings (including works by Paul Henry or Jack B. Yeats). Students move in groups to identify which techniques (overlapping, size change, atmospheric perspective) the artist used to create depth.
Think-Pair-Share: The Horizon Line
Students are given a blank page with just a horizon line at different heights. They discuss in pairs how the placement of that line changes the 'story' of the landscape (e.g., a low horizon emphasizes a big, dramatic sky).
Watch Out for These Misconceptions
Common MisconceptionObjects far away should be painted with the same bright colors as objects nearby.
What to Teach Instead
Students often use the same green for a distant hill as for the grass at their feet. A 'color matching' activity with photos helps them see that distance makes colors appear lighter, bluer, and fuzzier (atmospheric perspective).
Common MisconceptionThe horizon line is always at eye level.
What to Teach Instead
Students often draw the horizon at the top of the page. By using a physical 'level' or string in the classroom, they can see how the horizon moves depending on their own physical position (sitting vs. standing).
