I'd forgotten long division. Then my son needed it.

When my son gets a long division problem right, he gets so excited. He loves the thrill of it, and he high-fives me. Afterward he rewards himself with some kind of reward. Then we power through a bunch more.

He never really learned division, or long division, when he probably should have. He fell behind in school because of a bunch of schooling issues. So we've been going through a workbook together and doing a lot of long division. It's been really productive, and we've been having fun.

He has picked it up fairly quickly, like he does with all this math stuff. Meanwhile, I've been refreshing my own mind. I forgot how to do some of it, especially the flow of how you do long division. But it's super powerful, and I love it.

It isn't all high fives. When he gets frustrated, it sucks. We take a pause, and I slowly walk him back through things again. Sometimes I get a little frustrated, too, and I have to maintain my composure and try to be cool with him. I've lost it with him a few times, when he just isn't applying himself.

But if you power through that with him, it works out so nicely. Overall, it's really rewarding to sit and teach your kid something and feel good about the whole interaction together. It's nice.
