Classifying Two-Dimensional Figures
Students will classify two-dimensional figures into categories based on their properties, such as number of sides, angles, and parallel/perpendicular lines.
Key Questions
- Differentiate between various types of quadrilaterals based on their attributes.
- Justify why a square is also a rectangle, but a rectangle is not always a square.
- Construct a Venn diagram to categorize different polygons.
Ontario Curriculum Expectations
About This Topic
The final topic in the Grade 5 science curriculum focuses on human impact and the responsibility of stewardship. Students examine how our daily actions, from the products we buy to the way we dispose of waste, affect local and global ecosystems. They learn about the importance of biodiversity and the interconnectedness of all living things, realizing that a change in one part of an ecosystem can have far-reaching effects.
In Ontario, this unit emphasizes the importance of protecting our Great Lakes and vast forests. Students are encouraged to develop personal and community-wide strategies for reducing their ecological footprint, such as the 3Rs (Reduce, Reuse, Recycle) and water conservation. This topic is deeply rooted in the concept of reconciliation, as students learn from Indigenous perspectives on the sacredness of water and the responsibility to act as caretakers of the Earth for future generations.
This topic comes alive when students can design and implement a real-world conservation project in their school or local community.
Active Learning Ideas
Inquiry Circle: The Waste Audit
Students collect and categorize the waste produced in their classroom or lunchroom over one day. They weigh the different types (recycling, compost, landfill) and create a plan to reduce the 'landfill' portion by 20%, presenting their strategy to the school principal.
Simulation Game: The Watershed Game
Using a large tray of sand and water to represent a local watershed, students place 'pollutants' (like food coloring or glitter) at different points. They observe how the pollutants spread through the water system when it 'rains,' discussing how upstream actions affect downstream communities.
Think-Pair-Share: Stewardship in Action
Show a quote or video about Indigenous stewardship. Ask: 'What does it mean to be a caretaker of the land rather than just a user of it?' Students discuss in pairs and brainstorm one specific action they can take this week to be a better steward of their local environment.
Watch Out for These Misconceptions
Common MisconceptionRecycling is the best and only way to help the environment.
What to Teach Instead
Students often focus only on recycling. Teachers should emphasize that 'Reduce' and 'Reuse' are much more effective because they prevent waste from being created in the first place. A 'waste hierarchy' activity helps students prioritize their actions correctly.
Common MisconceptionOne person's actions don't make a difference in a global problem.
What to Teach Instead
Students can feel overwhelmed by issues like climate change. Teachers should use examples of collective impact, like how a whole school's composting program can divert tons of waste. Peer discussion about 'the power of one' helps build a sense of agency and responsibility.

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.
More in Space and Shape: Geometry and Measurement
The Coordinate Plane
Students will understand the coordinate plane, identifying and plotting points in the first quadrant.

Graphing Points and Shapes
Students will plot points on the coordinate plane to represent real-world problems and draw geometric shapes.

Understanding Volume with Unit Cubes
Students will understand volume as an attribute of solid figures and measure volume by counting unit cubes.
2 methodologies
Volume Formulas for Rectangular Prisms
Students will relate volume to the operations of multiplication and addition, applying the formulas V = l × w × h and V = B × h for rectangular prisms.
2 methodologies
Volume of Composite Figures
Students will find the volume of solid figures composed of two non-overlapping right rectangular prisms by adding the volumes of the non-overlapping parts.
