This game, Leng, has been developed to supplement the basic skills taught in the elementary school classroom. Leng is self-correcting, meaning students can work independently while still having the ability to check their work immediately.

Leng includes an activity book, an answer board and 12 different colored game pieces.

To begin playing Leng, open the activity book to the subject of your choice and place your answer board along the edge of the book. The goal is to correctly match questions or puzzles from the left side of the page to their corresponding answer on the right side of the page through a color-coded system. For example, if the question has a blue circle next to it, the player would place their blue circle game piece in the corresponding spot on the answer board. To check your work, simply turn the page and look at the answer key!
