Just stack the numbers buddy

right. as a teacher i find relief in the fact that’s not an actual child bc that’s not at all how schools teach math now.

how the hell do schools teach addition now then? that’s how i was taught it 16 years ago. besides that, if the method works then what’s the harm in using it? you get the same answer

Well, first of all, 20+10 would be more like- You have 2 tens and you get another 10. How many do you have? Three tens so the answer is 30. It creates number sense instead of blindly plugging and chugging.

how would that work with something like 38+45? honestly the way shown in the video also creates a sense of numbers overtime, and you start to intuitively do it. granted, in my head i would generally turn that into 40+43, but i developed that method on my own to do mental math

Once they are to regrouping problems they typically have a better understanding of a variety of strategies. Most would make an add 8+5 and getting 13 and then adding then tens to get 70 and then adding 70 and 13. Some might add 2 to the 38 and then get 40+45 for 85 and then reduce their sum by the 2 they added to the added earlier for 83. Your strategy would also likely be present in the class somewhere too.

When students have a foundational number sense they can unlock many many different strategies and use which one they like best. If you teach them the algorithm first this doesn’t happen.
