How to Break a Number into Two Parts (Example: 8, 8 = 5 +3) - Breaking numbers into two separate numbers is not difficult at all. You just have to determine what makes the entire number altogether. The bigger the number the longer the process can take for an individual to determine the breaks. For example, if you have a number 12345, then it can be divided based on the number you see. Like, 1234 + 5, 1230 + 45, 1200 + 345, 1000 + 2345. This division is based on the number that are visible. The other way of determining how the number is to be broken into two parts is by dividing the number by 2. This will ensure that the number be divided into two equal parts such as: 28/2 = 14 | 14/2 = 7 | 100/2 = 50 Last but not the least, a number can be divided into two parts through random division of the number. Such as: 28 - 7 = 21 | 100 - 92 = 8. These worksheets and lessons help students learn that whole numbers can be the sum of multiple numbers with the goal of being to write addition sentences.
