One of the things that has frustrated us with our 10 year old’s current school is that he has no text books. This makes it hard for us to look up how he’s learning things. It’s especially frustrating in math as they now learn different methods we did.
Recently, I was struggling to show him how to divide. (Well, I wasn’t struggling to show him how to divide but my way seemed to be completely foreign to him, as if he’d never learned it before. So I was struggling to build on what he already knew.)
So I asked his teacher how he had taught the class to divide, and he sent me back this work sheet with the “4 methods he had taught them”.
Nevermind that those are 3 methods and one explanation on how to write problems – I will admit that at times I’m a bit too pedantic about saying exactly what you mean. (But really, it’s math, you have to say 3 when you mean 3!)
While it seems like a good way to understand what division is all about, it seems to be lacking in ways to easily come up with the exact answer. But it does work to teach them how multiplication and division are related.
I also really liked that it was immediately followed up with word problems, i.e. “Mike has 32 cookies. He wants to share them equally with his 6 friends. How many cookies does each friend get?”
I hope there’s a next step where they learn how to divide the “good old-fashioned way”. Whether or not they do, I’ve already taught my 10 year old that way, although I had to teach him decimals as well. (I’m sure that when I first learned to divide, they very conveniently left out all problems with remainders and then added them in later.)
Which way do you think is the best way to teach kids about division?
