Basics on the topic Greater than / Less than

In this greater than less than video…

Dundee has arrived at Skylar and Henry’s and they are hungry! Skylar and Henry have some salad they can share with Dundee but they need to make sure they give Dundee the greatest amount each time. Let’s have a look at less than and greater than as well as the greater and less than signs.

Crocodile greater than less than

How do you remember less than greater than? We often remember the greater than less than signs by thinking of a crocodile, like Dundee! Just like Dundee, crocodiles are hungry so they will always open their mouths towards the greatest amount and the greater than less than symbol looks a bit like a crocodile’s mouth!

  • < - less than
  • > - greater than

Greater than and less than

Skylar and Henry have some carrots to give to Dundee. Skylar brings 15 carrots and Henry brings 26. Is 15 less than or greater than 26? 15 is less than 26. Once we know this we can write a maths sentence using a greater than or less than sign. This time we will use the less than sign: 15 < 26.

Greater or less than

To continue learning about greater than and less than have a look at our greater than less than worksheet as well as other interactive activities and exercises.

Transcript Greater than / Less than

"Henry, it's almost time for Dundee to get here, are you ready?" "Of course I am!"

"Hi, Dundee!" "Wait, I thought you were bringing food." "That's okay, we have some salad we can share with you!" While Skylar and Henry show Dundee the salad, they can use "greater than, less than" to talk about the amount of food. We compare numbers by talking about how big or small they are with the phrases greater than, or less than. Instead of writing the words greater than or less than, we use these symbols. Greater than is a way to talk about a number that is bigger than another. Less than is a way to talk about a number that is smaller than another. These symbols look like the opening of a crocodile's mouth, and the opening of the symbol ALWAYS points to the GREATER number. Just like Dundee always opens his mouth up for the bigger plate of food! Let's see what Skylar and Henry bring to Dundee first. Skylar brings Dundee fifteen carrots while Henry brings twenty-six. Is fifteen greater than, or less than twenty-six? Fifteen is less than twenty-six When we compare two numbers, we create a maths sentence and can read it. Just like when we read sentences in books, when we read maths sentences we read from left to right. If we compare fifteen and twenty-six, we would read it as fifteen is less than twenty-six. It looks like Dundee has requested even more food! Skylar and Henry bring out some cucumbers to impress Dundee. This time Henry brings out thirty cucumbers while Skylar brings out twenty. How can we compare their plates of cucumbers? We can compare using greater than or less than. Is thirty greater than or less than twenty? It's greater than! That means we will use the greater than symbol. If we read our maths sentence we would say thirty is greater than twenty. Before we get to that party, let's summarise. Today we learnt about greater than and less than. It's a way to compare numbers using symbols. Greater than is a way to talk about a number that is bigger than another. Less than is a way to talk about a number that is smaller than another. We also learnt about the symbols used when creating a maths sentence with greater than and less than. Remember that the opening of the symbol ALWAYS opens towards the bigger number like Dundee opening their mouth towards the greater plate of food! Now, let's see about that party! "What do you mean, they ate all of the food we gave them?" "It's okay, we'll order a pizza for the party!" "Next time, let's give him fruit so he doesn't eat all of it!"

  • Show which number is greater.

    Hints

    Count the images to work out which number is larger.

    Remember, the greater than and less than signs are like hungry crocodiles. The opening faces the larger number.

    Solution

    16 is the larger number, so we use the greater than symbol to say 16 > 12.

    The opening faces the larger number.

  • Which symbol fits in the gap?

    Hints

    Think about which number is greater. The opening of the symbol always faces the larger number.

    When we write the greater than sign, it faces the greater number: 65 > 44.

    When we write the less than sign, it faces away from the smaller number: 44 < 65

    Solution

    11 is less than 38.

  • Which sentence matches the picture?

    Hints

    Read the number, the sign, and the other number out loud to find your maths sentence.

    Remember, the maths sentence is read from left to right.

    For example, this reads fifty-three is greater than twenty-two.

    Solution

    The sentence that matches 61>12 is sixty-one is greater than twelve.

    We read the first number, sixty-one, followed by the sign, greater than, and the last number, twelve. The maths sentence is sixty-one is greater than twelve.

  • Which maths sentences are correct?

    Hints

    Remember, the two numbers are 7 and 14. Which number is greater?

    Try saying the maths sentence out loud.

    Solution

    The numbers were 14 and 7. Since 14 is greater than 7, we write it using the greater than symbol (14 > 7).

    Since 7 is less than 14, we write it using the less than symbol (7 < 14).

    Dundee is going to eat the 14 cupcakes, since that is the greater amount!

  • Complete the sentence.

    Hints

    Remember, the symbols (< >) look like a hungry crocodile's mouth!

    Look at the example 10 > 2. Is the opening towards the bigger or smaller number here?

    Solution

    The opening of the symbol always faces the bigger number!

    Just like Dundee opens his mouth towards the biggest pile of food, the symbol opens towards the bigger number. Example: 5 > 3, 3 < 5.

  • Match the number sentence to the symbol.

    Hints

    Remember, the symbol faces the larger number like a hungry crocodile.

    Read the number sentence from left to right.

    Solution

    We place the corresponding symbols by looking at which number is greater.

    The greater than symbol is represented by > and the less than symbol is represented by <.

    The crocodile mouth faces the greater number.
