[quote=Anonymous][quote=Anonymous]Welcome to Common Core where they teach math this way. I learned "carry the one" growing up. My oldest is learning multiple ways of adding (including the 35+51 example above). Teaching anything other than "carry the one" seems more complicated but I realized that for years, when adding in my head, I'll do the 35+51 method. [b] I just wouldn't have known how to teach or explain that. [/b] Now, don't get started on my oldest not memorizing multiplication tables. [/quote] I have a friend who loves Singapore Math for just this fact - that it explains ways people have simplified math for themselves after learning the algorithm (carry the one/borrow) years ago. But I'd argue the fact that you do this shows you understood basic addition and subtraction and it works better to learn the standard algorithm and the concept and then intuit the other methods from years of practice. That's what you did, and it worked.[/quote]
