The other way of determining how the number is to be broken into two parts is by dividing the number by 2. Like, 12340 + 5, 1230 + 45, 12000 + 345, 10000 + 2345.Īs students advance, they will be to work this skill seamlessly into their everyday. For example, if you have a number 12,345, then it can be broken down based on the numbers you see at each place value. Having the ability to decompose values will become second nature and students will learn to adapt this to much larger values. This simple skill really accelerates in future grade levels and is applicable to a great volume of material. We are left with 1 + 2 and the need to find what value when added to those numbers would make our needed value (9). This means that we need to knock off the last digits (3 + 4) because those are the values that make us spill over. ![]() Solution: Start with lowest whole number available (1) and keep add the next largest until you run over the number.ġ + 2 + 3 + 4 – This sum is 10 and runs over our needed value (9). Problem: What is the maximum number of parts you can break 9 into with whole numbers? Let's take a look at a problem that includes this and walk you through the steps to solving it: It is important to help students determine the maximum number of slices you can make of a number with other whole numbers. In this section we are focused on just getting to 10. The bigger the number the longer the process can take for an individual to determine the breaks. ![]() You just have to determine what makes the entire number altogether. It is a critical skill towards developing a solid number sense. Breaking numbers into two separate numbers is not difficult at all.
