Tool 2
Method Reminder
This quick guide reminds students what to do when they feel stuck.
- Read the story: what is the question really asking?
- Choose the method: identify the correct idea before calculating.
- Show the reason: do not skip the logic.
- Check the answer: make sure it fits the situation.
1. Pattern to Expression
Simple explanation: This section builds confidence with algebra by showing what each symbol means before manipulating it.
A key skill is taking a geometric pattern and converting it into an algebraic expression.
- Linear Patterns: First differences are constant. Pattern is
an + b. - Quadratic Patterns: Second differences are constant. Pattern is
an² + bn + c.
2. Simplifying Expressions
Simple explanation: This section builds confidence with algebra by showing what each symbol means before manipulating it.
Always follow the order of operations and collect like terms.
(a + b)(c + d) = ac + ad + bc + bd
(a + b)² = a² + 2ab + b²
(a + b)² = a² + 2ab + b²
Examiner Tip
💡 Examiner Tip: When expanding brackets like (x+3)², the most common error is writing (x²+9). Always write out (x+3)(x+3) to ensure you include that middle term (2ab)!📝 Exam Style Questions
Simple explanation: This section explains the main idea in simple English first, then builds toward the formal method used in exam questions.
Easy Q1: Expand (x + 5)(x - 2).
Medium Q2: Factorise x² - 9.
A1: x² - 2x + 5x - 10 = x² + 3x - 10.
A2: (x + 3)(x - 3) (Difference of two squares).
