How it works

Choose the kind of question above, then how many: 10, 20, 30 or 40.
Print the sheet. The student circles one answer per question. The answer key comes on a page of its own.
Or practise on screen. The same questions appear with options to choose from, and every answer is marked when you check. There is no score and no clock.
Keep the link. The address holds both the settings and the questions, so the same link gives the same sheet again.

Two kinds of question

Which is reasonable? Three values a power of ten apart, for example $0.20, $2 and $20 for an ice lolly. Only one of them lies in the reasonable range.
Compare. Which weighs more, a cat or a dog? Which costs more, a bus ticket or a plane ticket? Some questions ask about how many times as fast a cyclist is as a walker.

The ranges are reasonable, not measured: a price or a mass on the sheet is a fact inside the question, not a claim about what anything costs today.
