The way we write and pronounce numbers is quite different from English, but they are still as important to give or get some personal information. In this lesson, we will learn to write and pronounce Spanish numbers 1-20, “los números del uno al veinte“. You will find many examples of sentences with numbers in Spanish, common phrases with them and several interactive exercises to practice this topic. Let’s get started…

Writing and pronouncing Spanish numbers 1-10
LOS NÚMEROS or Spanish numbers can be divided in two main categories: cardinal and ordinal numbers. This lesson is about cardinal numbers, which are often used to share or get some personal information about ages, phone numbers and many other things. Spanish numbers 1-20 are all written differently, so we must memorize them because they are the basis for more complex numbers. UNO is a special case as it changes to UN when used before a masculine noun like CARRO (car), which means it would be correct to say “Un carro” (a car), but not “Uno carro”. The picture below uses sea animals (animales marinos) to show how to spell numbers from one to ten in Spanish.

| Uno – Una ballena Dos – Dos calamares Tres – Tres caballitos de mar Cuatro – Cuatro tortugas Cinco – Cinto cangrejos | Seis – Seis peces Siete – Siete peces Ocho – Ocho caracoles Nueve – Nueve pescados Diez – Diez pescaditos |

Making Sentences with Numbers in Spanish 11-20
The last group to complete our list of Spanish numbers 1-20 are those between 11 and 20, “los números del once al veinte”. They must be memorized too, but there is a simple pattern to follow for some numbers, particularly from 16 to 19.

For Spanish numbers from sixteen to nineteen, all you need to do is join the prefix DIECI- plus a SEIS, SIETE, OCHO or NUEVE. However, the number “dieciséis” is a special case because it needs a tilde over the “é”. The chart below shows how to pronounce and spell Spanish numbers 11-20, and shows how they can be used in meaningful sentences and questions. Again, we will be using the verbs TENER and HAY in these examples.

DOCE – El perro tiene doce años
The dog is twelve years old
