THE STORY
Read a short story (a walk, a filling tub, a cooling soup) and sketch its graph by dragging the dot that ends each part up, down or level — steeper means faster, and every sketch that tells the story is accepted.
A story unfolds in three or four parts — someone walks to the shop and stops to chat, a tub fills then drains, a phone charges then streams video — and the player sketches the matching graph of a quantity over time by dragging the dot that ends each part: up for increasing, level for constant, down for decreasing, and steeper when the story says faster. Three modes layer direction, pace (faster or slower than the previous moving part) and round trips that must end back at the start, and any sketch satisfying the story is accepted, so the focus is on qualitative features rather than one exact line. It targets the misconception that a graph is a picture of the path rather than a record of a changing quantity. Best for Grade 8 (8.F.5).
A free, no-signup, no-ads math game for Grade 8 — practising qualitative-graphs, increasing-decreasing, rate-of-change, interpret-graphs, piecewise-functions. Play in your browser on the KidsDoMath games hub or explore more Coordinates & Algebra games.
