What is on this sheet
A percentage is a fraction with a hundred underneath it, and the fastest route through most of these is to say that out loud: 25% is a quarter, 10% is a tenth, and 15% is a tenth plus half of it. A child who reaches for a formula on 50% of 60 has learned the wrong thing about percentages.
The amounts run from ten to two hundred, which is roughly the range a price tag, a test score and a recipe live in. That matters more than it sounds — the whole reason this topic is on the syllabus is that it is the one piece of school arithmetic an adult uses weekly.
The answers were worked out when the problems were, so the key is the same page with the answers drawn in rather than a second attempt at the same questions — there is no way for the two to disagree. The number in the footer is the seed the sheet was built from: it is printed so that the identical sheet can be had again next week, rather than one that merely looks like it.
Change what is on it
This page is one sheet out of a family that can print thousands, and the settings behind it — how many problems, how big the numbers get, how they are laid out, whether there is room to work — are all switches. The builder link at the top of the page carries this sheet’s own settings, so the bench opens on exactly the sheet here rather than on a blank one.
The configuration travels in the address bar rather than on a server, so the link can be bookmarked or sent to somebody as it stands — and what they open is this sheet, down to the seed, rather than another one like it.
