What is counting up method
the opposite of counting down ?
The "counting up" method is a strategy used in mathematics to simplify the process of addition or subtraction by starting from a number other than zero. It can be especially helpful when dealing with consecutive numbers or large numbers.
To understand the counting up method, let's use an example of adding two numbers: 8 and 5.
1. Start by selecting a number to count up from. In this case, let's choose 8 as our starting point.
2. Begin counting up from 8 by adding consecutive numbers until you reach the other number in the addition problem. In this case, we need to count up to 5.
- 8 + 1 = 9
- 9 + 1 = 10
- 10 + 1 = 11
- 11 + 1 = 12
- 12 + 1 = 13
3. After counting up to 5, add up all the numbers you used in the process: 8 + 1 + 1 + 1 + 1 + 1 = 13.
- 8 (starting number)
- 1 (added to get to 9)
- 1 (added to get to 10)
- 1 (added to get to 11)
- 1 (added to get to 12)
- 1 (added to get to 13)
So, the sum of 8 and 5 is 13.
The counting up method is a useful technique to break down addition or subtraction problems into smaller, more manageable steps. It can help build number sense and mental math skills.
