Questions about Setting the Bar and the Bounds

What does the Setting the Bar and the Bounds worksheet cover?

It practises defining a design problem with criteria and constraints — 3 questions for Grade 3 to Grade 5, all on Common Core 3-5-ETS1-1: Define a design problem, with what counts as success and what limits you. The instruction to pupils is “Sort each one into criterion or constraint”, and the answer key follows on the next sheet.

Which Common Core standard does Setting the Bar and the Bounds practise?

3-5-ETS1-1 — 3-5-ETS1-1, in the Engineering Design domain for Grade 3 to Grade 5. The published standard reads: “Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Setting the Bar and the Bounds is written for Grade 3 to Grade 5, typically ages 40-41. It is one of the sheets on 3-5-ETS1-1, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Setting the Bar and the Bounds come with an answer key?

Yes. All 3 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.

How many different versions of Setting the Bar and the Bounds can I print?

25 — one per pupil, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.

Is Setting the Bar and the Bounds free to print and photocopy?

Yes. Setting the Bar and the Bounds, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.

Is there a lesson plan to teach 3-5-ETS1-1?
