I take it all back!

This is hilarious.

Christopher came home today and said that in math they 'did measurement.'

I asked him if they did any measurements not starting from the 0 end of the ruler, and he said scornfully, 'We didn't do rulers. We did cups.'

Then he said, as an afterthought, 'Oh, Mommy! She taught us those unit multipliers!'

I love it!

I guess after nobody could convert 48 ounces to quarts she had the same thought I did:

UNIT MULTIPLIERS!

NOW!

BEFORE IT'S TOO LATE!

Naturally I'm feeling smug that my child was the only student in the class who'd heard of the things & knew how to use them.

update 7-16-2006: Smug is one thing; mastery is another. Christopher knew what unit multipliers were & how to use them, but he wasn't anywhere near mastery. We're starting unit multipliers again today. I'd like him to reach mastery/automaticity by fall, which I think should be possible. If not, this summer's unit multipliers will put him in good shape for the unit multiplier lessons he'll have in Saxon Algebra 1/2, which he'll be working his way through this summer and next school year.

update 9-14-2006: Christopher worked his way through 12 lessons of Algebra 1/2 and numerous pages of Vocabulary Workshop this summer. And that was about it. New target date: mastery of unit multipliers before college.
