Mastering Spanish Numbers 11 to 20
Teaching Spanish numbers 11-20 is an important step for students learning to count beyond the basics. These numbers are used by Spanish speakers in daily conversations, math, and telling time, making them essential vocabulary for beginners.
Once I moved my Spanish Curriculum for Middle School beyond a textbook, I stopped teaching numbers as a “unit.” Instead I used them in routined like Calendar Talk and in my Super 7 unit to start the year.
I know that may of you are tied to a set curriculum. So in this guide, we will break down how to teach Spanish numbers 11-20 effectively. We will compare them to Spanish numbers 1-10, and provide practical exercises to reinforce learning.
Reviewing Spanish Numbers 1-10
For anyone that knows a bit of Spanish vocabulary, they likely can count to ten in Spanish. As a refresher her are los números 1-10.
los números – numbers
- 1 – uno
- 2 – dos
- 3 – tres
- 4 – cuatro
- 5 – cinco
- 6 – séis
- 7 – siete
- 8 – ocho
- 9 – nueve
- 10 – diez
Understanding Spanish Numbers 11-20
Spanish numbers 11-20 follow a pattern that builds on what students have already learned from Spanish numbers 1-10. Here’s a simple list:
- 11 – once
- 12 – doce
- 13 – trece
- 14 – catorce
- 15 – quince
- 16 – dieciséis
- 17 – diecisiete
- 18 – dieciocho
- 19 – diecinueve
- 20 – veinte
Numbers 11-15 are unique words. These are typically the trickiest words for Spanish learners to remember.
1-10 are very common knowledge. 16-19 follow a pattern if you already know 1-10. 16-19 follow a pattern using “diez y” combined into a single word (e.g., dieciséis = diez y seis).
So 11-15 in Spanish are the numbers to focus on the most.

How Spanish Numbers 11-20 Differ from 1-10
- Numbers 1-10 are mostly short and simple (uno, dos, tres), while 11-15 introduce longer, less predictable words.
- Numbers 16-19 begin to follow a clear pattern, preparing students for numbers beyond 20.
- Unlike Spanish numbers 1-10, which are frequently used in greetings and simple counting, 11-20 are crucial for discussing ages, dates, and prices.
Pronunciation Tips and Common Mistakes
- Practice tricky numbers: Students often struggle with words like “quince” and “dieciocho” due to unfamiliar sounds.
- Listen to native speakers: Audio practice helps reinforce proper pronunciation and rhythm.
- Break down longer numbers: Teach students to separate “diez y seis” into “dieciséis” to help them see the pattern.

How to Use Spanish Numbers 11-20 in Real Life
Numbers 11-20 are used in many everyday situations. Some key examples include:
- Asking and answering about age: “¿Cuántos años tienes?” “Tengo quince años.” *Practice age in my High-Frequency Verb Unit to Start Spanish 1 focusing on the Super 7 verbs. Get it here.
