hello everyone today we're going to review a process that everyday math called partial sums addition the moms and dads I know that this process is totally different from the way that you and I were in to add when we were in school so I'd like to go through the steps the intention is helping students to better develop place value concept and from many problems and eliminates the need to carrier trade over turn other call you may have already shown your son or daughter how to add larger numbers using the traditional method with caring and that's great I would like them to know one understand both message and I will be explaining the traditional method in class as well but it's important for all the students learn and to understand how to do the partial sums method as well if a problem on a home worker test says that the partial sums what is to be used on the students will need to follow this method and show all of their steps if the problem does not specify then they'll be free to choose which method are most comfortable with for solving the problem so we can take a look at how to do partial sums addition I have this problem 243 + 326 + the first step is to begin in whichever the largest place columnist on this question it's the hundred so you can see and read the first step is to add 100 200 + 300 equals 5 when I wrote down my 500 I was careful to keep my digit lined up in the correct place value, the next step is to move to the next largest column which in this case is the tens column the 10th Psalm we have a hornet to so what we're actually doing is adding 40 + 20 + I've written down that 40 + 20 equals 60 and I again lined up my digits in the correct place value power  and then we move on Channel 1.com  in the ones column we have a 3 in at 6 so we're simply adding 3 + 6 equals 9 stop to the final step at the bottom of my problem I have all the adding that I've done so far by 100 my 60 and my 9 so we're showing in this problem how we broken down the the problem into the hundred the tens who won and we simply combine or add those together 500 + 60 + 9 equals 569 notice on this stop I have drawn in just to show you that you can make lines to show the place value columns if your child is having a difficult time keeping The Columns lined up drawing these lines might be a great idea for them if they're able to keep their tones lined up without the line then that's great too will you have it not too tough following the simple steps for the addition process when we do partial sums addition if you have any other questions feel free to watch this video again or use your SRB student reference book that your child should be bringing home every night provide additional explanations and example you can also always send me an email if you have any questions thanks
