Counting Fun with Numbers!

Hey there! Are you ready to have some fun with numbers? Let’s learn how to count past 100 and see how easy it can be!

Counting from 100 to 120

Counting past 100 is just like counting from 0 to 20. Let’s try it together:

First, let’s count from 7 to 20:

seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, and twenty.

Now, let’s count from 100 to 120 using the same pattern:

100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, and 120.

Counting from 109 to 120

Let’s try counting from 109 to 120. It’s just like counting from 9 to 20:

First, count from 9 to 20:

nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, and twenty.

Now, count from 109 to 120:

109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, and 120.

Your Turn to Count!

Now it’s your turn! Can you count from 104 to 120? Use the pattern from counting 4 to 20 to help you:

four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, and twenty.

Now try 104 to 120:

104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, and 120.

Counting Fish in the Sea

Counting can be fun with fish too! Let’s see how many fish are in the sea:

How many do you see? There were 12 fish in the sea.

How many do you see? There were 7 fish in the sea.

How many do you see? There were 10 fish in the sea.

How many do you see? There were 16 fish in the sea.

How many do you see? There were 20 fish in the sea.

Using a Number Line

We can use a number line to help us find numbers that come before and after. Let’s try it with some examples:

For 25: 25, 26, 27, 28, and 29.

To find the number after 33, we add 1: 33 plus 1 is 34.

To find the number before 33, we subtract 1: 33 minus 1 is 32.

Let’s try with 51: 49, 50, 51, 52, 53. The number after 51 is 52.

Great Job!

You’re doing great with counting! Remember, you can use a number line or simple addition and subtraction to help you find the answers. Keep practicing, and see you next time!

  • What are some things you like to count in your everyday life? Can you think of something you might count up to 100 or even more?
  • Have you ever used a number line before? How do you think it helps when you are counting or finding numbers that come before or after?
  • Imagine you are counting fish in the sea. What other sea creatures might you count, and how would you keep track of them?
  1. Number Line Adventure: Create your own number line at home using a long piece of paper or a string. Write numbers from 100 to 120 on small pieces of paper and place them in order along the line. Now, try jumping from one number to the next, saying each number out loud as you go. Can you jump from 104 to 120 without missing any numbers?

  2. Counting with Nature: Go outside and collect small objects like pebbles, leaves, or sticks. Count them in groups of ten, starting from 100. For example, if you have 15 pebbles, start counting from 100: “100, 101, 102, … up to 115.” How many objects did you find? Can you count them all?

  3. Fish Counting Game: Draw or print pictures of fish and write numbers on them from 100 to 120. Mix them up and spread them out on a table. Pick a fish and say the number out loud. Then, find the fish with the next number and continue until you reach 120. Can you do it without skipping any numbers?

Sure! Here’s a sanitized version of the provided YouTube transcript, removing any unnecessary repetitions and ensuring clarity:

[Music]

Counting past 100 is music to my ears! I know after 100, 101 is near.

100 to 103… everything is cool. You can find 104 lounging by the pool. 105 doesn’t lie. 106 is next. 107 doesn’t want to say it, but in 108, the best 109 and 110 are all with the cows. You can use this pattern to count until a thousand.

Let’s try it!

[Music]

Counting past 100 to 120, we can follow the same pattern that we used when counting from 0 to 20. You can even start counting at any number as long as you remember the pattern from zero to twenty.

Let’s count from seven to twenty:
seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, and twenty.

Now let’s try counting from 100 to 120. We can use the same pattern we just used to count from 7 to 20:
100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, and 120.

Can you see the relationship between counting from 0 to 20 and counting from 100 to 120? It’s quite similar; they follow the same exact pattern. This can help us count up starting at any number.

Let’s try it again! Let’s count from 109 to 120. We can follow the same pattern from when we count from 9 to 20.

First, let’s count from 9 to 20:
nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, and twenty.

Now let’s try 109 to 120:
109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, and 120.

Great work! Now it’s your turn. I challenge you to count from 104 to 120. You can use the pattern of counting from 4 to 20 to help.

I’ll give you some time to think, but if you need more time, you can pause the video and answer when you are ready.

[Music]

Okay, here’s the answer! Let’s count from 104 to 120. We can follow the same pattern from when we count from 4 to 20.

First, let’s count from 4 to 20 to find out the pattern:
four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, and twenty.

Now for 104 to 120:
104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, and 120.

Remember, you can use patterns to help you count starting at any number.

I am so excited to be back with you again today! We have this great worksheet called “Sweet Counting.”

Let’s read the directions: Help the cook number the cakes. Choose the correct numbers that go before and after the number that is shown, then check the correct answer.

I’m going to show you two different ways to figure out the answer.

Let’s look at the first one. We have a number, and we’re trying to find out what number comes after this number and what number comes before it.

The easiest way to do this is with a number line. A number line has numbers that are consecutive or go in order.

For example, let’s do 25:
25, 26, 27, 28, and 29.

This is an example of a number line. It could start on zero or anywhere.

Let’s say we want to find the number after 33. We can write:
33 plus 1.

That gives us the number to the right, which is 34.

Now let’s find 34.

Next, we need to find which number is smaller, so we subtract:
33 minus 1 gives us 32.

Now let’s make a number line.

If we start on 51, we want to find the next number.

Let’s think of a number smaller than 51, like 49:
49, 50, 51, 52, 53.

So for 51, the next number is 52.

Now let’s check 50.

Let’s do an addition and subtraction problem for this one.

67 plus 1 gives us 68.

And for subtraction, 67 minus 1 gives us 66.

Now for 100, let’s check it two ways.

Let’s do a number line with 100 in the middle:
98, 99, 100, 101, 102, 103.

For addition:
100 plus 1 gives us 101.

For subtraction:
100 minus 1 gives us 99.

Great job today on your counting!

Remember, we can use a number line or addition and subtraction to help us find answers.

See you again next time!
