Compensation: Making an Easier Problem to Subtract

[corysingleton]

Thanks for the video explaining it because now I have to teach it to my kid since his teacher clearly can’t, but in no way is this easier than the old way. My 2nd grader can subtract thousands vertically and can’t understand what they’re trying to get him to do here. This is wild.

They are not solving it mentally. They are solving it with this convoluted method. You want a little kid to make a tape diagram and add numbers that are not actually part of the problem. Why not teach 66 minus 28 vertically and teach then how to move a group of 10 into the ones column since you can't take away 8 from 6. Little kids don't need to do double digit addition in their heads but if they know the single digit facts by memory they will soon be able to do the mental math without being taught

Thank you! I did not learn this when I was in school. So imagine how confused I was when my daughter brought it home today😂. Thanks for such a clear explanation

Hi Ms. LeBlanc, I wanted to say that you are one of the few teachers who teaches strategies in a way for students to understand the math they are doing instead of just following some steps. Thank you so much for posting these videos.

Hey there Ms. LeBlanc. You did such a great job explaining this math strategy clearly. Thank you for taking the time to make and share this video.

Amazing video, deserves more attension

Call me old school (which is a compliment these days) (with 3 degrees in engineering) but why not just teach them how to do subtraction? I mean it's not terribly difficult to line the numbers up and perform the single digit operations. I taught my son when he was around 5 to do addition and subtraction the traditional way easily (adding and borrowing, what they call regrouping now). There is no addition or subtraction problem that can't be solved easily with single digit addition and subtraction and there aren't many things to learn to master it. I don't understand schools these days teaching all these convoluted methods instead of focusing on what works and mastering what works and what is simple. My sons schools hardly ever issue repetitive tradition math problems to create the memory of how to do them. So, I've had to spend a lot of time printing my own worksheets with like 50 addition and subtraction problems per sheet and have them do them at home. At least once a week. They have learned far more math at home than the schools could have ever provided. In fact my sons are so good at math they often get these silly problems with questions like 'What is the answer approximately' or 'what answer is the closest to the actual answer' or dumb stuff like that, and they quickly and efficiently get the actual real answer then have to go back and figure out what silly rounding or approximation the test maker did to find the test makers approximate answer. The way the USA teaches math now, I can tell you we are doomed in 20 years unless we import an absolutely ton of people from India, China and Finland, and other countries, who actually know how to do math and engineering, otherwise good luck with that bridge designed 'approximately' using compensation calculus and break-apart geometry/trigonometry.

So helpful for me. But what if you have a bigger number

[mariamwadea]

Thank you for this viedio it helps me in my classwork

[josherickson]

Next time pls, make your volume higher, cause all I heard was ants talking!

[ahavamiri]

Omg. So helpful thank you for much now I understand WAY better. Lol.

[lynnmix]

Thank u this helped my child to understand it better

[Dani-zvkf]

Thank you so much now I could help my daughter understand and let her watch your video

What are e compensating INTELLIGENCE ? JUST SUBTRACT THE DAMN NUMBERS STRAIGHT OUT
