How many groups of ten are there here?

How many tens are in this number?

Exploring tens and ones

﻿Introducing place value. Hello, everybody. I'm Miss Sidhu and we're going to be doing some amazing maths with you today. In this lesson, you will begin to use a place value chart to understand the value of numbers. A little bit like the place value chart I have here with the tens and the ones. Now, let's get started. Welcome to today's lesson and today we will be counting in tens and ones using a place value chart, an independent task and an end of lesson quiz to see everything that we have learned. You will need a pencil and a paper to write down any of the activities. And also a place value chart like this. I've just done the tens and the ones like this. Here, we have a big picture of "Jack and the Beanstalk" and the giant. He is counting his lovely golden coins, only this time, he's decided to put groups of 10 into bags and tie them up. How many bags of coins can you see? I want you to pause the video and have a look. So how many bags of coins can you see? Pause and freeze, macaroni cheese. How many did you count? Can you shout it out? Oh, I heard lots of you with the correct answer. Let's count them together. So we've got one bag of coins, two bags of coins, three bags of coins, four bags of coins, five bags of coins, six bags of coins and finally, seven bags of coins. There are seven bags of coins altogether. Did you get the same as me? Good job. So the giant has even more coins to bag and he has asked all of us to help him. Here, we have some 10 frames with coins already in but we need to count them. So let's count them altogether. We can start counting in tens 'cause we know there are already 10 in the 10 frame. So we've got 10, 20, 30, 31, 32, 33, 34, 35. There are 35 coins altogether. So let's check again. So we've got 10, 20, 30, 31, 32, 33, 34 and 35. There are 35 coins altogether. Here, we have two place value charts. This is where we break the numbers up to see what their value is. For example, here we have two bags in this column. In each bag, there are 10 coins so we can put the number two in the tens column on this place value chart. Remember, there's two bags of 10 coins. So we can put two in the tens column. This column is for the loose coins, all the ones, so there aren't enough to make 10. They go in this column. Let's count how many loose coins there are. So we've got one, two, three. There are three ones, so we need to write the number three in the ones column. So two tens and three ones, that makes 23. I want you to have a go at this one. You need to count the bags and write the number in the tens column and then count the loose coins or the ones and write the amount in the ones column. You can use your place value chart and write it down here with the tens and the ones. I want you to pause the video and have a go. So pause, think and then write it down. How did you do? Have a look at mine and see if yours is the same. There are two bags of 10 coins, so that makes two lots of 10. And there are five loose coins, which means there are five ones. Two tens and five ones make 25. You've done some super counting today and looking at the place value using the tens and the ones, I think you're ready for today's independent task. For your task today, you need to fill in the place value chart and the answers. You need to count the coins and write the number in the tens column, then count the loose coins or the ones and write the amount in the ones column. Remember, the coins in the 10 frames are already in groups of 10 and you can write them in your place value chart. I want you to pause the video to complete your task. Resume once you have finished. Let's look at the answers. So here we've got three groups of 10 and four ones, so there are 34 coins altogether. Here, we have two groups of 10 and seven ones and there are 27 coins altogether. If you would like, you can share your work with Oak National. Please ask a parent or carer to share your work on Twitter, tagging @OakNational and hashtag #LearnWithOak. You did a super duper job at beginning to use a place value chart to understand the value of numbers. Great work, everybody. Now I want you to complete the quiz to see everything that you have learned and that's the end of the lesson now. Bye!
