﻿Hello, everyone. I hope you're feeling great and are ready for today's learning. We have a special visitor with us today. Can you say hello, Reggie? Reggie says hello everyone. Oh buddy. What have you got here? Reggie says he's brought me a pen to help me with our learning today. Thank you very much Reggie. I already had a pen. And now Reggie's brought me another one. How many pens do I have now? Great, I've got two pens now. You did a good job there. What you did was add two quantities together. One add one makes two. And that's what we'll be doing a bit more of today. So for today, we'll be learning how to combine two quantities together to find a total. Here's what you'll need. You'll need a number line to help you with today's learning. Press pause now to go and get a number line, and I'll see you in a bit when you're ready. Welcome back everyone. Now that you've got your number line, you are ready for today's learning. Let's take a look at our star words for today. I am going to say them and you can repeat them after me. Are you ready? Part plus whole is equal to and altogether. Those are our star words for today. Now, I've got a special picture here with lots of maths in it that's going to help us with our learning today. Let's take a look at the picture. Here we are. Time for you to take a look. What maths can you see in the picture? Have a think. Reggie's been thinking about this picture too. Haven't you Reggie? Would you like to tell everyone what you saw? Okay. So here we are. Let's start here. There are two big cars here and a smaller car at the back. Two plus one is equal to three. There are three cars altogether. Two plus one is equal to three. There are three cars all together. Oh, Reggie says take a look at the green carriage of the first train here. There are one, two, three, four, five, six people in the green carriage in the first train. And there are one, two, three people in the blue carriage of the second train. Six plus three is equal to nine. There are nine people altogether in the green carriage and the blue carriage of the trains. Well done everybody. Now let's take a look at one more piece of maths that we can find in the picture. There's one driver here in this train and one driver here in the other train. How many drivers are there altogether? Shout the answer up to the screen if you know. Great. That makes two, there are two drivers altogether. One plus one is equal to two. Well done, everybody. That was great counting. Now let's have a look at some more maths learning that we're going to do now. I've got a special driver friend here. He's going to drive a train. I'm going to put him right here. And then I'm going to show you the passengers in the carriages of his train. So here we are. Here's the driver and there are two carriages in his train. There's a orange carriage and there is a grey carriage right here. How many people are in the orange carriage? Count them and shout your answer out to the screen when you're ready. Remember to use careful counting. Great. There are four people in the orange carriage. Let's count them together. One, two, three, four. Here we are . I'm going to put number four there, just to remind ourselves of how many people are in that carriage. Great. Now here comes my next question. How many people are in grey carriage? Use careful counting to count them and shout your answer out to this room when you're ready. I can hear some of you shouting the answer. Well done. There are seven people in the grey carriage. Let's count them together. One, two, three, four, five, six, seven. And here we are. Here's number seven for the grey carriage. Now here's the question. Oh, let's make sure we can see our train driver. How many people are on the train altogether? So we've got four people in the orange carriage, seven people in the grey carriage. How many people will be on the train altogether? You can use your number line to help you with this. See if you can work out the answer and then shout your answer out to the screen. Well done everyone. I can hear you trying to work out the answer. I am very impressed. Let's use our number line to help us with this. So let's put numbers up there so we can see. Here we are. So let's find out first number, which is number four. One, two, three, four. Then we need to add seven. So we're going to do seven jumps. You can count them with me. One, two, three, four, five, six, seven. Here we are. How many people will be on the train altogether? Eleven. Eleven people on the train altogether. And that is great because our train driver can't have more than 20 people on his train. And 11 is less than 20. Great job. Now our train driver is going to be driving another train. He's a very busy man. Let's have a look and see what the characters look like in his next train. So here we are. He's back again. Let's put another carriage here and another carriage here. So here's our other two carriages. And here is our train driver. How many people are in the first dark blue carriage? Use careful counting to help you and then shout your answer out to the screen when you're ready. Well done. I can hear a lot of you shouting out the answer. Let's count them together. One, two, three, four, five, six, seven, eight. There are eight people in the first carriage. And here we are. We're going to use a number card to show number eight here. How many people are in the second carriage? Shout your answer out. Great. One There is one person in the second carriage. Now here's a question for you. How many people will be on the train altogether? How many people on the train altogether? Use careful counting to help you. You could also use your number line to help you work out the answer. Shout your answer out to the screen when you're ready. I can hear a lot of you shouting out the answer. Let's take a look. So our first number is number eight. One, two, three, four, five, six, seven, eight. And we need to add one more. One. Here we are. Here is our answer. Eight plus one is equal to, shout it out. Nine. Well done everyone. Eight plus one is equal to nine. You have been doing an amazing job at helping me add these quantities together. Give yourselves two claps. Well done. Now I'm going to show you something else. So our answer was nine and here we are, our whole number was nine. Let's take a look at the numbers that made our whole number. Let's take a look at the two parts. So we had eight in our first carriage. And one in our second carriage. Eight plus one is equal to nine. So nine is made up of our two parts with this eight and one. Well done everybody. Now it's your turn to practise adding two quantities together using the carriages on the slides that are attached to this video. See how many different quantities you can find. Will they be more than 20 or less than 20? Have a go and practise that and I'll see you again next time. Take care.

In this lesson, we will practise adding 2 quantities together by counting them all.
