Even or odd numbers on number lines

key notes :

What are Even and Odd Numbers?

Let’s learn about even and odd numbers!

• Even numbers are numbers that can be divided into two equal groups. Think of sharing cookies equally with a friend – if you can share them all, it’s an even number!
• Odd numbers are numbers that can’t be divided into two equal groups. If you try to share them, there will be one left over.

Even Numbers on a Number Line

Even numbers always end in 0, 2, 4, 6, or 8. They’re like the friendly, shareable numbers!

Look at this number line:

0️⃣ 1️⃣ 2️⃣ 3️⃣ 4️⃣ 5️⃣ 6️⃣ 7️⃣ 8️⃣ 9️⃣ 1️⃣0️⃣

Let’s highlight the even numbers:

🟢0️⃣ 1️⃣ 🟢2️⃣ 3️⃣ 🟢4️⃣ 5️⃣ 🟢6️⃣ 7️⃣ 🟢8️⃣ 9️⃣ 🟢1️⃣0️⃣

See how they skip one number each time?

Odd Numbers on a Number Line

Odd numbers always end in 1, 3, 5, 7, or 9. They’re the numbers that have a ‘leftover’ when you try to share!

Let’s look at the same number line again:

0️⃣ 1️⃣ 2️⃣ 3️⃣ 4️⃣ 5️⃣ 6️⃣ 7️⃣ 8️⃣ 9️⃣ 1️⃣0️⃣

And now let’s highlight the odd numbers:

1️⃣ 🟠1️⃣ 2️⃣ 🟠3️⃣ 4️⃣ 🟠5️⃣ 6️⃣ 🟠7️⃣ 8️⃣ 🟠9️⃣ 1️⃣0️⃣

They also skip one number each time, just like even numbers!

Let’s Practice!

Is 3 even or odd?

Imagine you have 3 cookies. Can you share them equally with a friend?

🍪🍪🍪

No! One cookie will be left over. So, 3 is an odd number.

Is 6 even or odd?

Imagine you have 6 toys. Can you divide them into two equal groups?

🧸🧸🧸🧸🧸🧸

Yes! Each group can have 3 toys. So, 6 is an even number.

Next Steps

Now that you know about even and odd numbers, try these things:

Ask your family to play the even-odd game! Choose even or odd. Then call out a number. If your number is the type of number you selected, you get a point!

Count all the toys you have. How many are even and how many are odd?

When you see a number, try to guess if it’s even or odd.
