Welcome to Smile and Learn! Today, we’re going to have some fun with numbers and learn how to tell if a number can be divided by six. Imagine we’re making salads, and each one needs six olives. Let’s use the divisibility rule of six to help us!
If a number is divisible by six, it means you can divide it by six without leaving any leftovers. To figure this out, we need to check two things: if the number can be divided by two and by three.
The first step is to see if the number is divisible by two. This is easy! Just look at the last digit of the number. If it’s an even number (like 0, 2, 4, 6, or 8), then it passes the rule for two. For example, if our number ends in eight, it’s even, so it works!
Next, we need to check if the number is divisible by three. To do this, add up all the digits in the number. Let’s try it with 108. Add 1 + 0 + 8, and you get 9. Since 9 can be divided by three, 108 passes this rule too!
Now that we know 108 is divisible by both two and three, we can say it’s also divisible by six. So, when we make our salads, each one will have six tasty olives!
We’ve learned a lot about numbers today! There are so many more things to discover. If you want to keep learning and having fun, check out more videos on the Smile and Learn channel. Who knows what exciting things you’ll learn next!
Olive Counting Game: Gather a group of small objects, like buttons or coins, to represent olives. Ask the children to count out different numbers of “olives” and check if they can be divided into groups of six without any leftovers. Encourage them to use the divisibility rules for two and three to verify their results. This hands-on activity helps them apply the concept of divisibility in a fun and practical way.
Number Detective: Give the children a list of numbers and ask them to be “number detectives” to find out which numbers are divisible by six. They should use the rules for two and three to solve the mystery. For example, they can check numbers like 24, 35, and 42. Encourage them to explain their reasoning for each number they investigate.
Divisibility Hunt: Ask the children to look around their home or classroom for numbers they encounter in everyday life, such as on clocks, books, or signs. Have them choose a few numbers and determine if they are divisible by six using the rules they learned. This activity encourages them to observe and apply math concepts in real-world situations.

Welcome to Smile and Learn! Today, we’re exploring numbers that are divisible by six. The recipe says we need to add six olives to each salad, so we will apply the divisibility rule of six, which is one of my favorites!
To determine if a number is divisible by six, we need to check if it meets the divisibility rules for both two and three. Let’s start with the rule for two. Remember, we check if the last digit is even. Our number ends in eight, which is even, so the rule for two is satisfied.
Now, let’s check the rule for three. To find out if a number is divisible by three, we first add its digits. For 108, the sum of the digits is 1 + 0 + 8, which equals 9. Since 9 is divisible by three, that means 108 is also divisible by three.
Since 108 is divisible by both two and three, we can conclude that it is also divisible by six. So, when we add olives to the salads, each salad will have six delicious olives!
