Jessica has 2 apples. Anna has 4 oranges. How many fruits are there?
That is Addition.
What is Addition?
How many fruits?
Let’s count them together!We use the addition symbol + to write addition equations
How does we solve it?
+ = ?1 2 3 4 5 6
There are 6 fruits in total!
Let’s write this equation out with numbers!
How does we write it out?+ = 6
2 + 4 = 62 apples
4 oranges6 Fruits!
We can also solve addition problems with number lines and number tables!
How to solve it?
7 + 6 = ?Draw out a number line like this!
1 2 3 4 5 6 7 8 9 101112131415
We can also solve addition problems with number lines and number tables!
How to solve it?Now just count 6 parts from 7 until you reach your answer!
1 2 3 4 5 6 7 8 9 101112131415
1 2 3 4 5 6
7 + 6 = 13We have the answer!
This is a number table up to 100!We use this to solve addition problems up to 100!
How to solve it?
Number Tables are also used for division, multiplication and subtraction!
It is a very useful method when working with numbers!

32 + 8 = ?Let’s try this problem!
1 2 3 4 5 6 7 8 9 10

71 72 73 74 75 76 77 78 79 80
81 82 83 84 85 86 87 88 89 90
91 92 93 94 95 96 97 98 99 100
So we start at 32 and count 8 blocks and find the answer!1 2 3 4 5 6 7 8
We solve it! 32 + 8 = 40!
32 + 8 = 40
Now that we have learnt Addition, let’s try a few problems ourselves! Have a go at these simple addition problems!

6 + 3 = _____8 + 2 = _____4 + 4 = _____1 + 3 = _____7 + 1 = _____9 + 2 = _____3 + 3 = _____2 + 1 = _____4 + 2 = _____
5 + 8 = _____2 + 5 = _____4 + 5 = _____5 + 6 = _____7 + 6 = _____9 + 4 = _____6 + 6 = _____7 + 7 = _____8 + 7 = _____
13 + 5 = _____12 + 2 = _____14 + 7 = _____13 + 7 = _____15 + 8 = _____19 + 2 = _____14 + 12 = ____15 + 13 = ____18 + 15 = ____
Advanced Addition is adding big numbers! For example, 35 + 28 = ?We use a method called Long Addition to work out complicated sums!
Advanced Addition
Did you know? With Long Addition, you can divide any number you want, no matter how big it is!
What’s 4532 + 73829 = ?Use Long Addition!
+ + + + + +
Long Addition is really easy! Let’s try this sum 235 + 4420 = ?
Long Addition
Our first step is to arrange the numbers in a specific way. Draw a line and align the numbers!
2354420 235
4420
Note: Align the tens with tens, hundreds with hundreds and thousands with thousands. This example is wrong.
+ 2354420+
Both ways are correct! 5 + 2 = 7 and 2 + 5 = 7
Long Addition is really easy! Let’s try this sum 235 + 4420 = ?
Long Addition
Now all we have to do is add each column and we have our answer!
2354420+
50 + 5 = 5 So we write 5 at the bottom!
2354420+
55
Step #1 Step #2
3 + 2 = 5 So we write 5 at the bottom
Long Addition is really easy! Let’s try this sum 235 + 4420 = ?
Long Addition
Now all we have to do is add each column and we have our answer!
2354420+
4 +2 = 6 So we write 6 below the column!
2354420+
Step #3 Step #4
4 + nothing = 4!
655 4655
And we have the answer! 4420 + 235 = 4655 and 325 + 4420 = 4655
