Welcome to our beginner ESL lesson on numbers from 20 to 100. Your students will learn the rules for forming and pronouncing these numbers in English. This knowledge is essential for basic arithmetic and everyday scenarios such as shopping, telling time, or discussing ages.

This lesson plan is ideal for teachers who prefer an organised approach. It starts with a clear boardwork recommendation and moves on to several low-resource activities that help students practice and become more familiar with numbers. To end on a high note, the plan includes a couple of classroom game suggestions that are both fun and reinforce the students' newfound numerical skills.

Low-resource ESL lesson plan

Use of the board

The students learn the rules for forming and pronouncing numbers from 20 to 100 in English.

Start by stepping through the multiples of ten up to a hundred. Practice for as long as you feel you need to before moving on. After that, demonstrate how we form the other numbers. Elicit as much as possible by pointing to the board and using your fingers.

Low-resource ESL activity

Number talk

An excellent little pair-work activity where students practice the target language for the lesson.

First, divide the students into pairs. They will then take turns writing down numbers for their partner to say out loud. You should monitor for the correct pronunciation.

Low-resource ESL activity idea

There are how many?

The students will attempt to make statements containing numbers from prompts that you'll write on the board.

Start by taking note of the exact number of specific classroom objects; tables, chairs, students, fingers, hands, books etc. Next, write the following type of phrase on the board:

  • There are twenty-five of these in the classroom.

Then, encourage the students to respond using the construction below:

Student: There are 25 chairs in the classroom.

Finally, add some more prompts and have the students work in groups to write the correct responses in their notebooks.

Low-resource ESL activity idea

ESL counting circle

The students will count in a circle with the aim of reaching as high a number as possible without making a mistake.

Start by arranging the group into a circle. Then, in a clockwise direction, students take turns saying the next number. If an error is made, we start over. The mistakes counted could be repetition, waiting too long, or another student shouting out the correct answer. Mix it up by switching to odd and even numbers or simple multiples.

ESL Buzz

In this fun elimination game, students must count in a circle, omitting a number based on a given multiple.

Start by arranging the students into a circle. Then, explain to the students that they have to count in a circle, but can't say numbers that correspond to a specified multiple. For example, if the multiple is 3, they must say “buzz” instead of 3, 6, 9, etc. Start off with easy numbers first. If a student makes a mistake, they are eliminated from the game.

ESL Bingo

A straightforward version of bingo that you can play with younger students.

Divide the students into pairs and have them draw a 4*4 grid on a blank piece of paper. Tell them to complete it with numbers from 1-100. Next, start calling out numbers at random and adding them to the board. You could use a random number generator app on your mobile or tablet. There are a few available for free on the Android Play Store and Apple App Store. Below is an example scoring system:


  • Any straight line: 50 points
  • Diagonal line: 100 points
  • Double line: 200 points
  • X shape: 500 points
  • Bingo: 1,000 points
