Even Numbers Explained with C#
Even numbers are an important concept in mathematics, and they're also a great way to introduce coding to beginners. In this tutorial, we'll show you how to list even numbers in C# using simple loops and conditional statements. This activity is designed for primary students, teachers, and parents who want to combine math learning with fun programming exercises.
What Are Even Numbers? | Maths Explanation for C# Kids
Hello pupils, what are even numbers?
Even numbers are integers that can be divided by 2 without leaving a remainder. Examples include 2, 4, 6, 8, and 10. Understanding even numbers helps students build a strong foundation in math and prepares them for more advanced coding challenges.
How to List Even Numbers in C#
Considering how simple and straight-forward even numbers are, writing a C# code for even numbers serves as a great way to introduce our Mathematics educational activities for young learners.
Let's write a simple C# program that prints even numbers between 1 and 100. Bear in mind, we use only a loop and a simple conditional statement for the C# code. This is a perfect math coding activity for kids and beginners.
Creating C# Files
Create a new C# Project;
call it Arithmetic.
Create a new C# Class file;
call it EvenNumbers.
Type out the adjoining C# code for listing even numbers.
How to run C# Codes
Run the C# code from the main function class by pressing
key f5 or the Start symbol.
How the C# Even Numbers Code Works
In this code, we use a C# loop to go through numbers from 1 to 100.
The conditional statement i % 2 === 0 checks if a number is divisible by 2. If it is, the number is printed as an even number.
- The variable `start` starts at 2, which is the first even number.
- The `while` loop continues running as long as the number is less than or equal to 100.
- Each even number is displayed on the screen.
This C# even number loop is suitable for primary school students and beginners learning to code.
Why Learn Even Numbers with C#?
Learning even numbers with C# helps students connect maths with coding. Instead of writing numbers by hand, students can use programming to generate number patterns quickly and accurately.
This primary school C# maths lesson:
- Reinforces understanding of even numbers
- Introduces basic programming logic
- Builds confidence in using C#
- Encourages problem-solving and logical thinking
Summary: Even Numbers and C# Programming for Beginners
Learning how to list even numbers in C# is a simple yet powerful way to combine math and coding. Whether you're a teacher, parent, or student, these math coding activities make programming fun and educational.
Using C# to list even numbers is a great way to introduce young learners to programming. It shows how computers follow instructions step by step and how maths concepts can be applied in real coding examples.
This lesson forms part of a wider approach to teaching maths and coding for primary learners through practical, hands-on examples.
So! C# Fun Practice Exercise - List Even Numbers
Teachers can use this C# even numbers tutorial to make math lessons more engaging. Students not only learn about even numbers but also practice basic programming skills.
As a fun practice exercise, try extending the activity by asking students to try out their own boundary values, and see how the C# code lists the even numbers between those boundary values.

list_of_primes.Add(start);
}
start = start + 1; // increase 'start' by 1
}
return list_of_primes;
