About

Grid Spin

Read full description

Grid โ€ข Spin-A-Win is a great way to introduce basic graphing concepts and coordinate pairs. The app presents a two-player game where the object is to place four tokens in a row using coordinates pairs. A player's turn consists of spinning two spinners to generate a coordinate pair. Once the coordinates are given the player needs to locate the position on the grid. Special sound effects make the app even more fun to use and the interactive design facilitates engaging learning strategies.
