Printable A4 worksheets from the Stacked Bar Model — Ratio teaching tool. The bars are printed with one box per part and the amount from the question bracketed onto the part of the model it measures, so a student works on paper exactly as the class did on the board — and then draws the bars themselves.
The paper
A box a student can write in is about 10 mm across, so a question whose ratio needs more room than its column has is printed across two or more columns automatically. At Small no bars are drawn at all — that paper is fluency practice for a class that has left the picture behind.
Sections — and how many of each
The order is the teaching, and the picture comes off last. A, B and C are the tool's three question types with the bars already drawn — what changes is where the amount in the question sits on the model: around the whole thing, over one bar, or over the gap between them. D gives an empty space and asks the student to draw the bars themselves, which is the step that shows whether the model is theirs yet or still the page's. E asks for it in words, with no picture at all.
Options
Everything but the bars is off to begin with, so the plainest paper is the default and each extra is a deliberate choice. The one part line puts the hinge of the whole method on the page — find what one box is worth and everything else is multiplication — and is worth turning on for a class that keeps jumping straight to an answer. The check line prints 5 × ___ = 75, so an answer can be tested rather than believed. The thinking prompt is a misconception to argue with. The answer key shows one part and the reasoning, not just the totals, so it can be handed to a student.
