Questions about How Much Longer?

What does the How Much Longer? worksheet cover?

It practises the difference between two lengths — 16 questions for Grade 2, all on Common Core 2.MD.A.1: Measure things with a ruler. The instruction to pupils is “Work out each answer”, and the answer key follows on the next sheet.

Does How Much Longer? come with an answer key?

Yes. All 16 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.
