Addition is adding something on.
When you add everything together, you get a total.
Look at this addition.
16 + 7 = ?
Start at 16 and count 7 forwards.
You can use the number line below to help you.
What do you get then?
16 + 7 = 23
If you use the number line to help you, start on the number 16 and bounce your finger along the line 7 places to the right. You should get to 23.
Remember that when you add, you always move to the right.
Let's try adding 8 to a number now.
19 + 8 = ?
You need to count forwards 8 places. If you use the number line, start at 19 and bounce your finger along 8 places to the right and what do you reach?
19 + 8 = 27
How about this one?
15 + 9 = ?
You need to move forwards 9 places on the number line and you'll arrive at 24.
15 + 9 = 24
There is another way that you could work this one out. 9 is one less than 10. If you add on 10 and then subtract 1, it will be the same as adding 9. Does that make sense?
Let's try: 15 + 10 = 25 - 1 = 24
Let's try some questions now.
