Cheat Sheet

  1. Solving Linear Equations -

    Master the steps to isolate variables by applying inverses: addition, subtraction, multiplication, and division. For example, to solve 3x + 4 = 19, subtract 4 then divide by 3 to get x = 5. A helpful mnemonic from Khan Academy is "Keep Change Change Keep" when handling inequalities so you remember when to flip the sign correctly.

  2. Pythagorean Theorem Applications -

    Recall that in any right triangle, a² + b² = c², where c is the hypotenuse. Practice with classic triples like 3-4-5 or 5-12-13 to quickly check your work. According to NCTM guidelines, visualizing squares on each side can cement this formula for your final exam grade 9 preparations.

  3. Balancing Chemical Equations -

    Use the law of conservation of mass: atoms before and after a reaction must balance. For example, in 2H₂ + O₂ → 2H₂O, you start by adjusting coefficients to equalize each element on both sides. Chemistry resources like ChemLibreTexts recommend listing element counts in columns to streamline the process.

  4. Key Literary Devices -

    Identify metaphors, similes, personification, and irony to analyze texts deeply. For instance, Shakespeare's "All the world's a stage" uses metaphor to compare life to theater. The Purdue OWL suggests creating flashcards for each device to boost recall before your 9th grade practice test.

  5. Major Historical Themes -

    Focus on cause-and-effect patterns in events like the Industrial Revolution or World War I, often summarized by the "M.A.I.N." mnemonic (Militarism, Alliances, Imperialism, Nationalism). Mapping timelines visually, as recommended by BBC Bitesize, helps you link dates and developments. This strategy is invaluable when tackling question 9 or any tricky history prompt on your grade nine quiz.
