Where does MEP teach...

[Gentlemommy]

Subtracting with borrowing multiple times? Like 4,002-2,216? Dd wants to do this problem, and I want to make sure I'm teaching her in the same way MEP will. She can subtract with some borrowing, like 4,536-2,229, she would know to do the thousands, hundreds, and then 36-29.

I just need to know how MEP teaches borrowing from a zero I guess...

Thank you!!!

FWIW we just did the out-loud part of Year 4 lesson 103, and it's the first time I or my daughter remember seeing a problem with borrowing from a 0, and later down the problem (it was a multiple-step problem) there was some multiple-borrowing going on.

 

Really the way MEP seems to be teaching that is by asking out-loud problems with the child is generally expected to do the problems mentally, and therefore in chunks. They're prepping the kids to subtract hundreds and then tens, or whatever makes it easiest to do mentally. I haven't seen it teach the standard algorithm yet.

My son did some, inc borrowing from zero or having to go over multiple places, in 3B, but had been doing it in his head before that.
