Extending Place Value to 1000
Students will extend their understanding of place value to include hundreds, representing numbers up to 1000.
Key Questions
- Analyze how adding a hundreds place changes the way we read and write numbers.
- Differentiate between the hundreds, tens, and ones places in a three-digit number.
- Design a model to show the number 458 using base ten blocks.
Ontario Curriculum Expectations
About This Topic
Plant Diversity and Survival explores the specialized structures plants use to grow, survive, and reproduce in various environments. Students examine how roots, stems, leaves, and seeds are adapted to specific conditions, such as the need for light or water. This topic aligns with the Ontario curriculum's focus on life systems by highlighting the diversity of plant life and the ingenious ways seeds disperse to ensure the next generation's success.
By investigating local flora, students gain a deeper appreciation for the botanical diversity in their own province. This topic is highly suited for collaborative investigations where students can observe plant behavior firsthand. When students work together to solve 'survival challenges' or model seed dispersal, they move beyond memorizing parts to understanding the functional purpose of plant structures. Active exploration turns the school grounds or classroom plants into living laboratories.
Active Learning Ideas
Inquiry Circle: Seed Dispersal Design
Small groups are given 'seeds' (beads or beans) and craft materials to design a structure that helps the seed travel by wind, water, or sticking to fur. Groups test their designs and explain which natural method they are mimicking.
Gallery Walk: Plant Adaptations
Place photos of plants from different Canadian habitats (tundra, deciduous forest, wetland) around the room. Students rotate in pairs to identify one specific feature that helps each plant survive in its unique home.
Think-Pair-Share: The Sun Seekers
Show a video or a real plant leaning toward a window. Students think about why the plant does this, pair up to discuss what might happen if the plant was turned around, and share their predictions with the class.
Watch Out for These Misconceptions
Common MisconceptionPlants get their 'food' from the soil.
What to Teach Instead
Students often think soil is food rather than a source of nutrients and water. Use a structured discussion to explain that plants make their own food using sunlight, while soil acts more like a vitamin or a steady base.
Common MisconceptionSeeds are not alive until they are planted.
What to Teach Instead
Many children believe seeds are 'dead' objects. A hands-on dissection of a soaked bean seed reveals the tiny embryo inside, helping students understand that a seed is a living thing in a dormant state.

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.
