Primary 5 - Math Unit 2: Number Relationships and Equations

Mastery Station: Integrating Equations, Factors, Multiples, and Patterns

Click any sentence to listen 👆

In this final review station for Unit 2, we integrate all algebraic and number-theoretic concepts mastered throughout the unit. Students synthesize equation solving using inverse operations and bar models, prime factorization via factor trees, applications of GCF in partitioning and LCM in scheduling cycles, and pattern rules. This rigorous review prepares students to excel in standard digital assessments with confidence.

🧠 Unit 2 Master Synthesis

Equations & Variables

Variable represents an unknown; equations have (=); solved via inverse operations or bar models.

Number Theory & GCF/LCM

Primes have 2 factors; GCF divides both (equal groups); LCM is shared multiple (meeting times).

High-Order Problem

Two prime numbers sum to 16 and their product is 55. What are the two numbers?

Solution: The prime factors of 55 are 5 and 11, and 5 + 11 = 16. The numbers are 5 and 11.
