12 comprehensive GCSE and iGCSE Maths worksheets with detailed step-by-step solutions. This complete algebra and number revision bundle is ideal for Key Stage 4 exam preparation, homework, and independent consolidation.

Save hours of planning time with this classroom-ready, 12-worksheet maths bundle! Specifically tailored for Key Stage 4 (KS4), this resource package is mapped directly to the core topics assessed by major exam boards, including Edexcel, AQA, OCR, and Cambridge IGCSE (both Higher and Foundation tiers).
Every worksheet in this pack features a complete, step-by-step worked solution key. Rather than just providing a list of final answers, these handwritten-style sheets show the full working out. This design facilitates rapid grading for teachers and enables students to independently spot and correct their mistakes during revision sessions.

What Topics Are Covered in This Bumper Pack?
• Calculator Use & Numerical Accuracy: Students learn to tackle complex multi-step fraction operations, square roots, and currency metrics. Focuses heavily on rounding answers to 2 decimal places and 3 significant figures.
• Changing the Subject of a Formula (Rearranging Equations): Scaffolded problems that guide pupils to isolate single variables. Includes linear terms, fractional expressions, powers, roots, and equations requiring factorization.
• Factoring Binomials (Linear & Algebraic Factorisation): Focused drilling on factoring out the Highest Common Factor (HCF). Progresses logically from basic integers to expressions with mixed variables and indices.
• Factors, Multiples, and Primes: Deep numerical skill enhancement. Practice includes identifying factor pairs, finding the Least Common Multiple (LCM), Lowest Common Factor (LCF), listing primes up to 40, and completing contextual word problems.

Ideal Delivery Options:
• Graded mastery practice or classroom starters
• Structured weekly homework packets
• Hassle-free, zero-prep emergency cover lessons / sub plans
• Targeted intervention blocks for students aiming to secure a strong pass
