Mahjong Chem

Based on the poplar Mahjong game, Mahjong Chem uses chemistry concepts as pieces of the puzzle. When selecting puzzles, users have the option of choosing from a variety of chemistry concepts, including metric prefixes, element symbols, electron configuration, polyatomic ions, and double-displacement reactants. When solving the puzzle, Mahjong Chem requires users to match one set of tiles to another set, and Mahjong Chem allows users to select from 11 different tile arrangements to increase or decrease the level of difficulty. Mahjong Chem uses a timer, keeps score, and provides hints.

Instructional Ideas

1. When reviewing different chemistry units, this app could be used as friendly competition between pairs or small groups of students to see who finishes first.
2. After students have studied the difference between ionic and molecular compounds, they could be assigned to play the Molecular or Ionic Mahjong game to reinforce their learning. The students could take a screen shot of their results and email it to the teacher as a homework or classwork assignment.
3. When students have learned electron configuration, they can practice in class by selecting this app’s Valence Electron game option.
