Hey there! Did you know you can figure out if a number can be divided by 2, 5, or 10 just by looking at its last digit? Let’s explore these cool tricks together!
Let’s start with the number 246. To see if it’s divisible by 2, we need to check if it’s an even number. Numbers that end in 0, 2, 4, 6, or 8 are even. Since 246 ends with a 6, it is divisible by 2!
Now, let’s try another number. Is it divisible by 2? Look at the last digit. If it ends with a 7, it’s an odd number, so it can’t be divided evenly by 2.
Next, let’s see if 154 is divisible by 5. The rule here is simple: if a number ends in 0 or 5, it’s divisible by 5. Since 154 ends with a 4, it can’t be divided by 5.
Let’s try another number. If it ends in 5, then it is divisible by 5. Easy, right?
Finally, let’s check if a number is divisible by 10. This one’s super simple! If a number ends in 0, it’s divisible by 10. If it doesn’t, then it’s not.

Number Hunt: Go on a number hunt around your house! Look at different items like books, toys, or food packages. Write down the last digit of the numbers you find. Can you tell if each number is divisible by 2, 5, or 10? Share your findings with a family member and explain how you figured it out!
Divisibility Detective: Become a divisibility detective! Create a list of 10 random numbers. Use the divisibility rules to determine if each number is divisible by 2, 5, or 10. Draw a picture or write a story about how you solved each mystery. What clues did you use to crack the case?
Build a Number: Use building blocks or LEGO pieces to create numbers. Each block represents a digit. Build a number and check if it is divisible by 2, 5, or 10 by looking at the last block. Try changing the last block to see how it affects the divisibility. What happens when you change the last block to a 0, 2, 5, or 8?

Hello and welcome to Tutoring Hour! Did you know that you can tell if a number is divisible by 2, 5, or 10 just by looking at its last digit? In this video, we’ll walk through the divisibility rules for 2, 5, and 10.
Let’s check if our first number, 246, is divisible by 2. The trick here is to look for even numbers. If a number has 0, 2, 4, 6, or 8 as its last digit, then it is divisible by 2. The number 246 has 6 as its last digit; therefore, it is divisible by 2.
Now, how about this number? Is it divisible by 2? We’ll check the last digit. Since 7 is an odd number, it does not pass the divisibility test for 2.
Next, we’ll check for divisibility by 5. Is the number 154 divisible by 5? The rule states that a number is divisible by 5 if it has 0 or 5 in its ones place. The number 4 in the ones place indicates that 154 cannot be evenly divided by 5.
Let’s move ahead and test if our next number is divisible by 5. Following the rule for 5, this number ends in 5; therefore, it is divisible by 5. Pretty simple stuff!
Lastly, we can tell a number is divisible by 10 if it has 0 as its last digit. It is clear that this number is divisible by 10, while the previous number is not.
This brings us to the end of our video. Solve division problems quickly with these handy tricks. If you want to learn more and practice, then tutoringhour.com is the place to be.
