Comparing and Ordering 3-Digit Numbers
Students compare and order numbers up to 1000 using place value understanding and symbols for greater than, less than, and equal to.
Key Questions
- How do we compare two 3-digit numbers using place value?
- What strategy helps us order a set of numbers from smallest to greatest?
- When are two numbers equal, and how do we show this?

About This Topic
Balance and weight transfer are core components of non-locomotor skills that build body control and stability. In Primary 2, students move from simple static balances to dynamic weight transfers, such as moving from two feet to one foot, or from feet to hands (as in a bear crawl or a simple rock). This topic is vital for gymnastics, dance, and even daily safety, as it teaches students how to recover their balance when off-center.
By engaging the core muscles and understanding the concept of a 'base of support', students learn how to stay steady. The curriculum emphasizes the use of different body parts as bases, encouraging creativity and physical problem-solving. This topic comes alive when students can physically model the patterns, testing which body parts provide the most stable foundations through trial and error.
Active Learning Ideas
Inquiry Circle: The Human Bridge
In small groups, students must create a 'bridge' where they transfer their weight onto at least three different body parts (e.g., two hands and one foot). They must hold it for five seconds while a teammate checks for stability.
Think-Pair-Share: Base of Support
Students try balancing on one foot with their arms tucked in, then with arms out wide. They discuss with a partner which position felt more 'wobbly' and why, then test balancing on different numbers of body parts.
Station Rotations: Balance Points
Create stations where students must balance on 1, 2, 3, and 4 points of contact. At each station, they must find three different ways to pose, emphasizing weight transfer as they move between poses.
Watch Out for These Misconceptions
Common MisconceptionStudents believe that holding their breath helps them balance better.
What to Teach Instead
Teach students to breathe normally and focus their eyes on a still point (a 'focal point'). Using a 'think-pair-share' activity where they try both methods helps them realize that breathing keeps the body relaxed and stable.
Common MisconceptionChildren think a smaller base of support is easier to balance on.
What to Teach Instead
Demonstrate that a wider base (like feet apart) is more stable than a narrow one (like tip-toes). Have students experiment with different widths of their 'base' to feel the difference in stability.

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.
