# How Dominoes Can Be Used to Teach Math and Science

Dominoes are more than just a fun game for kids. These little black and white rectangles can also help children learn basic math and logic. They can be used to teach about fractions and the speed of falling objects. They can even be used to model the function of nerve cells, called neurons.

Dominoes come in many different shapes and sizes. Each one has a line down the center, separating it into two squares. Each square has a number of spots, or pips, that mark its value. The most common domino set consists of 28 pieces. Each domino can be arranged in different ways to play many different games.

In general, dominoes are played by placing a tile on the edge of another domino. The tiles must be placed so that their matching ends touch fully. A single tile can be placed side to side or across a double. If a player can not place his tile, he knocks or raps the table and pass play to the next player. If the game reaches a point where no player can proceed, then the players are awarded points according to the combined sum of the number of pips on the remaining tiles in each player’s hand.

Most of the most popular domino games fall into one of four categories: bidding, blocking, scoring, and round games. Most of these games require a standard double-six domino set. In most cases, the dominoes are shuffled and then gathered into what is called the boneyard or stock. Then, each player draws seven tiles from the stock and begins playing. The rules of each game may differ slightly from one another, but most of them involve placing a domino edge to edge against the next tile. The winner of a game is the first player to make a play that will result in his opponent having no more tiles left on the table.

Several factors determine how fast a domino will fall when it is toppled. For example, the size of the piece and its surface area will affect how quickly it will fall. Its weight and surface area will also influence its velocity. It is not uncommon for a large domino to take several minutes to fall completely.

Lily Hevesh, who created a Guinness record for the largest domino installation, takes a few precautions when she builds an enormous domino display. She starts by considering the theme or purpose of the project. Then she brainstorms images and words she wants to use. She then draws a plan for how to arrange the dominoes.

Hevesh uses fractions to help her figure out how many dominoes she needs for a particular project and how they should be positioned. She then checks the physics of the setup, making sure that the lines of dominoes will fall at the correct speed. Finally, she omits a few dominoes until the very end of her work. This way, if an accidental topple occurs, it won’t bring the entire project crashing down.
