Argh! Bar Models.

I don't know. I just don't know.

We did a word problem today. With algebra. Yes, yes, I know I posted awhile back that Catherine finally got the bar models in Singapore Math. Thing is, she got them but she doesn't like them.

We read the question. We determined what the unknown was. Catherine whipped up an equation, 2a plus 3a over 2 equals 1044.(I wrote it out because I don't know how to knock out "over 2" on a keyboard). Sure, it could have been simplified a bit but she created it so we did the math. I then did a bar model (it was so much easier for me!), decided it was 1044 divided by 3.5 and did the math. The answers matched.

Now granted, algebra is coming much easier to me these days then it ever has before but how come she finds it so easy?

Just a note. It wasn't all roses. Her multiplication was sloppy and her spelling (on a worksheet)...Oh my. I just won't mention that. At least she's not shy about trying to write anymore. But oh my.

My husband swears that one can progress naturally from addition and subtraction to algebra. At one time I would have sworn he was wrong, but my children seem to be proving otherwise.
