Students locate hidden treasure from coordinate clues across all four quadrants over multiple rounds, with hot and cold feedback guiding each guess and quadrant behaviour explained as they go. The full interactive is available to licensed Education Universe users.
Ask students to explain their next guess using the feedback from the last one.

Students investigate congruence through translations, rotations and reflections. They work through a structured sequence identifying corresponding sides and angles,…
Students investigate why bees build hexagonal honeycombs by comparing area, perimeter and tessellation of regular shapes, testing efficiency and completing a wax-budget…
Four classic loci, including the perpendicular bisector, parabola and ellipse, are each introduced as a question and then revealed through an animated construction as…
Students try the historic seven bridges puzzle, discover Euler's graph rule, redesign the network and explain why crossing every bridge exactly once is impossible. The…
Students drag two vectors and see the resultant update live, switching between the head-to-tail method and the parallelogram law. The full interactive is available to…
Coordinate Treasure is one of the licensed interactives in The Education Universe. This page describes it; teachers use it in lessons and classes with a licence or the free trial.
