Let's Get to the Point

A coordinate-grid game where you slide, spin, and flip a point to match a target using translations, rotations, and reflections. Play solo in Practice, Genius in Training, or Geometry Genius modes, or race a friend head-to-head. Controls: arrow keys or WASD to move, space or enter to confirm answers, mouse to click menu buttons.

Teaching Notes for Educators

Let's Get to the Point covers the full geometric transformations unit - sliding a point with a translation, spinning it with a rotation, and flipping it with a reflection - using both algebraic coordinate rules and a hands-on tracing-paper tool for verifying each move experimentally. All three transformation types live in the same game, so a lesson can move seamlessly from one to the next instead of feeling like three separate topics.

A hands-on rotation tool, digitized. Rotations use an interactive tracing-paper overlay - place a pencil at the center of rotation, then physically turn the paper - the same manipulative many teachers already use on paper, now with instant, exact feedback.
Four-tier progression. Practice (self-paced, with hints), Genius in Training (speed-run with a personal best time), Geometry Genius (harder: rotation centers off the origin, multi-vertex shapes, fewer visual supports), and Head-to-Head (two players race the same grid).
Diagnostic feedback, not just "wrong." A missed answer is analyzed for the specific mistake - clockwise/counterclockwise confusion, reflecting over the wrong axis, swapping x and y, moving only one coordinate - and shows a tailored visual explanation for that exact error.
Scaffolding that fades as difficulty rises. Distance labels and direction arrows guide translations and reflections in the easier modes, and are deliberately removed in Geometry Genius so stronger students aren't held back by training wheels they no longer need.
Two ways to be right. A 180° rotation reached by going clockwise or counterclockwise lands on the same point either way - the game recognizes and praises this instead of marking a mathematically valid path wrong.
Both notations, side by side. Translations appear in algebraic form (x + 3, y + 2) and in plain language ("3 units right and 2 units up") across different questions, building fluency with both ways transformations get described.
Low-stakes practice. Unlimited retries in Practice and Genius in Training, no accounts, and no permanent record of mistakes.
Head-to-Head for review days. Two students solve the same challenge on the same grid at the same time - first correct answer wins the round - built for the kind of competitive energy a whole-class review deserves.
