Sequencing numbers within 50.
Hello everybody.
It's Miss Sidhu here.
And we're going to produce, some wonderful maths with you today.
In this lesson, you'll be using numbers to 50 in sequences by putting them in order from the smallest to the greatest.
Now let's get started.
in today's lesson, We will be recognising numbers within 50, ordering numbers within 50, and independent task and end of lesson quizzes, to see that everything that we have learned.
Now, let's see what we have today.
In today's lesson, you will need a pencil and a paper to write down any answers.
And during the lesson, you may need to pause so that you can have a go, at some of the activities yourself.
Now here, we've got little brainteaser to warm up our brains for today's lesson.
Now let's begin the lesson by matching the numbers, to the correct word form.
I want you to pause the video and have a go, pause and freeze macaroni cheese.
How did you get on? Does yours much mine, check to see if you got them Correct.
Good job everybody.
Here we have a big picture of Jack and the bead stalk and the giant.
Can you tell the person in the room with you, what you can see in the picture? Otherwise you can tell me.
I see lots of you say the apples and the trees, You could see Jack, you could see the giant.
What do you think the giant is doing? That's right.
He's counting his gold coins.
So how many coins do you think the giant has? Drawing this unit, You will be learning about numbers from 20 to 50.
And I think the giant must have at least 30 gold coins.
What do you think? Here, we have a number line lots of you might've seen a number line before, and we are going to have a go, counting from 20 all the way to 50.
Can you point to the number 20? The number 20, and we are going to count all the way to 50.
Are you ready? We're going to start at 20.
And when we start to turn to, we can click until we get to 30.
Are you ready? And then we'll do a different thing to 40.
And then although to 50, are you ready? Set go, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.
Let's do a clap the counter from 30 to 40.
So we've got, 30, 31, 32 33, 34, 35, 36, 37, 38, 39, 40.
And we can tap on our shoulders for 40 to 50.
So to get started at, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, and 50.
Good job everybody for counting from 20 all the way to 50.
And those are the numbers, that we're going to be using today.
To super counting everyone.
Now let's have a go at counting backwards from 50 to 40.
If you know the numbers, you can say them before they appear.
50 49, 48, 47, 46, 45, 44, 43, 42, 41, and 40, super counting everyone, wow.
I'm so impressed with your accounting today.
Now, here we've got a number square and a number grid.
What patterns can you see on this number square? I want you to pause the video and have a look and then tell the person next to you, to pause the video and have a look.
What patterns can you see on this number square? What did you find out? I found out that a long the columns, the numbers get bigger, so the numbers are getting greater.
I also notice that the first column goes along in tens.
So it goes zero, 10, 20, 30, 40.
And then for each of the column, the number ends in the number from the first row like this one.
So here, we've got the number four, and each number ends in the number from the first row.
So we've got 14, and then we've got our four again, then, 24, 34 44.
Did you notice anything else? Can you say it nice and loud so I can hear? Good job, I noticed that you saw that the pattern in the other numbers too.
Now, where would the number 37 go on our line? So where would the number 37 go, on this washing line of numbers.
Can you point to where you think it goes? Why do you think that? I think it will go around here, because there's other numbers that need to go before it, because we still need to do the number 33, 34, 35 and 36 before we get to 37.
How did you do, did you get the same as me? What are the missing numbers here? Here have Jack and his bead stalk, and the bead stalk has some missing numbers.
Let's help Jack to find the missing numbers.
Let's have a go at answering these questions.
What is one more than 22? You may want to use a beach drink or a number line to help you.
So what is one more than 22? So one more than 22 is, 23, So there's 22, then 23, 23 is one greater than 22.
Let's say altogether, 23 is one greater than 22.
Now let's try this one.
What are the missing numbers? So one more than 28.
What could be one more than 28? Can you tell me, great work? It's 29, 29 is one greater than 28.
Let's say the sentence together.
29 is one greater than 28.
Excellent work.
I think you're ready for today's independent task.
For your task today.
Can you help Jack, find the missing numbers in these sequences? Well, we've got some apples there as well.
I want you to pause the video to complete your task, and resume once you finished.
Let's have a look at the answers.
Here are the answers.
So the sequence goes, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23.
So this sequence it goes, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36.
I hope you had fun doing all of the numbers in sequence.
If you would like to share your work with Oak National, please ask your parents or carer share your work on, Twitter, Instagram or Facebook, tagging @OakNational and #LearnwithOak.
You did such a great job today, with helping Jack sequence numbers to 50, by putting them in order from the smallest to greatest.
I want you to complete the quiz to see, everything that you have learned.
Bye.
