Adding and Subtracting Integers
Students will practice addition and subtraction of integers using number lines and conceptual models.
Key Questions
- Explain why subtracting a negative integer is equivalent to adding a positive integer.
- Predict the sign of the result when adding integers with different signs.
- Design a visual model to demonstrate the sum of two negative integers.

About This Topic
Composition and framing are the 'grammar' of visual art, dictating how a viewer interacts with an image. This topic focuses on the Rule of Thirds, focal points, and the balance between positive and negative space. For Year 7 students, moving beyond 'centering' every subject is a significant developmental milestone. They learn to use the edges of the frame to create tension or harmony, and how to lead the viewer's eye through a work using implied lines.
In the Australian context, this can be explored through both contemporary photography and traditional Indigenous perspectives on space and perspective. Students learn that where they place an object is just as important as the object itself. Students grasp this concept faster through structured experimentation with viewfinders and collaborative photo-taking missions that require them to reframe the same subject in multiple ways.
Active Learning Ideas
Inquiry Circle: The Viewfinder Challenge
Students use cardboard viewfinders to 'crop' different areas of the classroom or playground. They must find three different compositions of the same scene: one balanced, one showing tension, and one using the Rule of Thirds, then photograph or sketch them.
Simulation Game: Human Composition
Using a large taped-out rectangle on the floor, students act as 'elements' in a painting. A student 'director' moves their peers around to demonstrate how changing the distance between subjects creates different moods, such as isolation or community.
Peer Teaching: Focal Point Swap
Students create a simple collage but leave the 'focal point' separate. They swap their background with a partner, who must then decide where to place the focal point to create the most interesting narrative, explaining their choice to the creator.
Watch Out for These Misconceptions
Common MisconceptionThe most important part of the picture should always be in the middle.
What to Teach Instead
Centering can often feel static or boring. Through active 'reframing' exercises, students discover that placing subjects off-center creates movement and a more professional look.
Common MisconceptionEmpty space is 'wasted' space.
What to Teach Instead
Students often try to fill every corner of a page. Using negative space simulations helps them see that 'emptiness' provides a place for the viewer's eye to rest and emphasizes the main subject.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
