Domino is a flat, thumbsized rectangular block bearing from one to six dots or pips and having a line in the center that divides it into two parts; the sides may be blank or carry a number of points. It is one of 28 tiles that make up a complete set of dominoes (plural: dominoes). A domino is also the foundation for a game of dominoes, in which players build chains of dominoes by placing adjacent pieces so that their ends match, either identically or forming some specified total.

Domino’s success as a pizza chain is due to several factors, including an emphasis on the use of high-quality ingredients and a focus on efficiency in operations. Another factor is its positioning of its stores near college campuses, which attracts customers looking to place orders for delivery. The company has expanded internationally, and in the US, Domino’s now operates 25,000 locations, making it the second-largest pizza chain.

Throughout its history, Domino’s has been a leader in innovation. The company pioneered the use of automated systems for delivery, and it has been experimenting with drones and other technologies to improve its pizza-delivery services. Despite this, Domino’s has remained true to its core values, which include listening to its employees and customers. As such, the company has developed a reputation for being a good employer and is one of the Best Workplaces in Michigan.

The most basic domino game is played with a double-six set, which consists of 28 tiles. A shuffled pile of these tiles forms the boneyard, from which players draw seven tiles each turn. They then place the tiles on-edge, so that they can see their own pieces but not the value of the opponents’. The player who has the least value of his or her remaining tiles wins.

This simple activity is a great way to introduce the concept of addition to students, as it can help them visualize that adding numbers in any order produces the same result. It can also help bridge the gap between using moveable manipulatives and understanding the commutative property of addition through written symbols.

Dominoes are often used to create art, such as pictures that form when the pieces fall. Domino artists, such as the YouTube user Hevesh, create intricate designs that can take several nail-biting minutes to fully fall.

In many domino shows, builders compete by arranging hundreds or even thousands of dominoes in carefully coordinated sequences that will eventually topple with the nudge of just one.

Dominoes can also be arranged in 3D structures, like towers and pyramids, to make a domino landscape. This is a popular hobby for adults, as well as children. Domino landscapes are also a fun way to teach geometry concepts. In these lessons, students learn how to construct a 3D shape from a set of dominoes and apply the principles of geometry to the construction of other structures. The lesson includes activities for both whole-class and small-group instruction.
