The Addition Symbol
00:00:05.070 --> 00:00:16.620
In this video, we will learn how to read, write, and model addition expressions with numbers up to 10 and represent addition using the plus sign.
00:00:18.760 --> 00:00:22.880
This is the addition symbol in maths.
00:00:22.880 --> 00:00:30.090
When we see this symbol, it means add or plus.
00:00:32.720 --> 00:00:43.630
The addition symbol tells us that we need to add together these two groups of counters and find the total number of counters.
00:00:45.170 --> 00:00:55.350
In this addition expression, we’re being asked to add together two counters and another two counters.
00:00:56.570 --> 00:01:00.620
We would read the expression as two plus two.
00:01:02.530 --> 00:01:07.170
To help us find the total number of counters, we could use a five frame.
00:01:08.500 --> 00:01:11.930
Then we can place all of the counters together and count the total.
00:01:13.360 --> 00:01:20.760
One, two, three, four.
00:01:22.510 --> 00:01:26.990
So we can say that two plus two is four.
00:01:28.840 --> 00:01:36.330
Let’s practise using the addition symbol to read, write, and model addition sentences.
00:01:40.060 --> 00:01:41.720
How many ducks are there?
00:01:43.790 --> 00:01:46.490
We’re shown two groups of ducks.
00:01:48.030 --> 00:01:52.980
And in the middle of the two pictures of ducks, there’s an addition symbol.
00:01:54.530 --> 00:01:58.120
This symbol means add or plus.
00:01:59.840 --> 00:02:06.370
We have to add the two groups of ducks together and find the total number of ducks.
00:02:07.880 --> 00:02:10.410
Let’s use some counters to help us.
00:02:12.520 --> 00:02:20.950
In the first picture, there are one, two, three ducks.
00:02:21.950 --> 00:02:27.210
In the second picture, there are one, two ducks.
00:02:28.620 --> 00:02:32.340
What is three plus two?
00:02:34.260 --> 00:02:39.050
If we put all of the counters together, we can count the total.
00:02:40.490 --> 00:02:43.520
Let’s count how many counters we have altogether.
00:02:44.480 --> 00:02:52.870
One, two, three, four, five.
00:02:52.870 --> 00:02:57.100
Three plus two is five.
00:02:57.560 --> 00:03:02.820
Count to find the total.
00:03:02.820 --> 00:03:03.710
Three add four.
00:03:03.790 --> 00:03:14.040
In this question, we’re being asked to add three green bricks and four blue bricks.
00:03:14.040 --> 00:03:22.610
In other words, we’re being asked to find the total number of bricks.
00:03:24.410 --> 00:03:29.210
If we add both groups of bricks together, we can count the total.
00:03:30.620 --> 00:03:44.360
One, two, three, four, five, six, seven.
00:03:45.910 --> 00:03:48.520
Three add four is seven.
00:03:52.610 --> 00:03:55.000
What is three plus two?
00:03:56.260 --> 00:04:00.460
Is it four, five, or one?
00:04:02.790 --> 00:04:13.490
If we place three counters into a five frame and then we add two more, how many counters do we have altogether?
00:04:15.220 --> 00:04:17.340
We don’t even need to count.
00:04:17.690 --> 00:04:20.080
The five frame is full.
00:04:21.730 --> 00:04:24.220
That means the total is five.
00:04:25.070 --> 00:04:27.860
Three plus two is five.
00:04:29.760 --> 00:04:32.740
This five frame only has four counters.
00:04:33.090 --> 00:04:35.630
We know that three plus two is five.
00:04:37.370 --> 00:04:40.040
This picture shows five counters.
00:04:41.480 --> 00:04:43.210
This is the correct answer.
00:04:43.710 --> 00:04:46.550
Three add two is five.
00:04:48.240 --> 00:04:50.020
What have we learned in this video?
00:04:51.710 --> 00:04:54.820
We’ve learned how to recognise the addition symbol.
00:04:55.970 --> 00:05:01.770
And we’ve also learned how to read, write, and model addition sentences.
00:05:03.270 --> 00:05:10.980
We’ve learned that the addition symbol means plus, add, or and.
