In this activity, we will add together five single-digit numbers.
Example
Find the total of these five single-digit numbers.
2 + 6 + 5 + 8 + 2 =
Answer
The order in which you add numbers is not important, but we can look at ways that make it easier to add all the numbers together.
2 + 6 + 5 + 8 + 2
Look for pairs that add to 10.
Here, the final 8 + 2 = 10
The 6 + 5 = 11
So, we have 2 + 11 + 10
which is 13 + 10 = 23
The answer is 23
In this activity, we will look for easy ways to add the numbers together.
