Hi! Did another post this morning with a similar comment, and don't want to be repetitive, but don't know how to cross-reference, so apologies if I sound like the AoPS marketing squad today....
Art of Problem Solving's Beast Academy might suit your DD (
http://www.artofproblemsolving.com/Store/beastacademy.php). From my own experience and consistent with many reviews I read, the kids who respond most to AoPS tend to be very visual-spatial, "whole-to-parts" learners, and math-inclined.
My main experience is with the older kids pre-algebra/ algebra, but Beast Academy is a distinct curriculum, currently available for grades 3 and 4 (I'm trying to entice my 2E DD8 into the grade 3 - we'll see. DS10 is the math man). The books are all comic form, and a lot of parent reviews I saw described kids (both much older and younger) reading them over and over for pleasure, with or without working through the associated math problems. So even if grade 3 is a bit more than you were looking for, I get the impression you can take them as lightly or substantially as your kid is inclined to go. DD carried them everywhere she went for a week (I have the whole grade three set) and perused them endlessly (looking more than reading, which she doesn't enjoy) - though I am still trying to get her to do any of the actual math!
AoPS is American, but we never really noticed. In the pre-alegebra course we only had to Google conversion factors once (seriously - 5280 feet in a mile? Thank god for metric). There were money questions, but it didn't make any difference that their dollars aren't Canadian dollars... and most of them were actually in problems that involved converting between multiple currencies. (The "feet" question came up in conversions too, now that I think about it.)
