Algebraic Proportion Escape Room | Y11 GCSE Math | Pirate Theme
⚓ Crack the vault. Claim the treasure. A print-and-go algebraic proportion escape room for 10th Grade GCSE Math (Higher). Students work as a salvage crew decoding Captain Morgan's final cipher — a four-digit vault lock guarded by algebraic puzzles on direct proportion (y ∝ x, y ∝ x²), inverse proportion (y ∝ 1/x, y ∝ 1/x²), and finding constants k. What's inside • 19-slide PowerPoint that drives the lesson — setup → puzzle → reveal rhythm for all four clues, with lock digits clicking into place

Adding and Subtracting Integers Made Easy (Bundled Unit)
Show Me the Money! Many math students struggle with combining integers. Textbook rules, number lines, and manipulatives often confuse students who then run into snags on subsequent concepts. Because everyone deals with money (usually from a very young age), I found that relating integers to money is very intuitive for students at any level – upper elementary to algebra. You will be amazed how quickly and painlessly your students will finally grasp adding and subtracting integers. Included in th
