Questions about Copying What Already Works
What does the Copying What Already Works worksheet cover?
It practises solving a human problem by mimicking a plant or animal part — 2 questions for Grade 1, all on Common Core 1-LS1-1: Solve a human problem by copying a body part that helps a plant or animal survive. The instruction to pupils is “Draw a line from each living thing to what it inspired”, and the answer key follows on the next sheet.
Which Common Core standard does Copying What Already Works practise?
1-LS1-1 — 1-LS1-1, in the Life Science domain for Grade 1. The published standard reads: “Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.” The worksheet assesses that standard rather than a paraphrase of it.
What age or grade is this worksheet for?

Does Copying What Already Works come with an answer key?
Yes. All 2 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 Copying What Already Works 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.

Yes. Copying What Already Works, 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.
