Prime Numbers and Composite Numbers
Students define and identify prime and composite numbers, understanding their unique properties and role in number theory.
Key Questions
- What makes a number prime, and why is 1 not considered a prime number?
- How can we efficiently determine if a large number is prime or composite?
- Why are prime numbers considered the 'building blocks' of all other integers?

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.
