Domino — 5/5 — free printable diagram

How many spots are on the 5–5 domino?

This domino has 5 spots on one half and 5 spots on the other, so it is worth 10 in total.

One half

5

Other half

5

Total spots

10

Addition

5 + 5 = 10

Double?

Yes

• Each half of a domino carries its own number of spots, and the tile's value is the two halves added together: 5 + 5 = 10.
• Both halves match, so this tile is a double — the double 5. A double-six set has seven doubles, one for each number from blank to six.
• As a doubling fact it reads double 5 is 10, and backwards as half of 10 is 5.
• A full double-six set has 28 tiles: every pair of numbers from blank to six once each, counting a tile and its turned-round twin as the same tile.
