Fourth grade math and eighth grade science

I don't mind proofreading a multiplication table (rule something-or-other is that there can be a typo in anything), but every time I look at a problem that's basically about the children learning the relative sizes of pints, cups, and quarts, or similar, I find myself thinking "can't we just do this in metric?" There's nothing wrong with practicing their eight-times table, but I doubt that students elsewhere in the world keep being handed questions like "which is larger, 2 liters or 230 milliliters?" On the other hand, points to Louisiana for noting that the way to learn how the two systems relate is "a meter is slightly longer than a yard" rather than precise conversions that leave students thinking only in inches and yards.

2 Pallas is not the largest asteroid. The IAU did not redefine "asteroid" when they introduced the "minor planet" category last year, but even if they had, 4 Vesta is larger in two of three dimensions and significantly more massive.

Sometimes the editorial notes (this place uses Word and "track changes") are straightforward things like "there is no question 4 here" next to a deleted entry for it in the answer guide, and sometimes they're paragraphs about astronomy or evolution.
