Questions about The Path Light Takes

What does the The Path Light Takes worksheet cover?

It practises modelling how reflected light entering the eye lets objects be seen — 2 questions for Grade 4, all on Common Core 4-PS4-2: Model how light bouncing off a thing and into your eye lets you see it. The instruction to pupils is “Number the steps from 1 to 4”, and the answer key follows on the next sheet.

Which Common Core standard does The Path Light Takes practise?

4-PS4-2 — 4-PS4-2, in the Physical Science domain for Grade 4. The published standard reads: “Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

The Path Light Takes is written for Grade 4, typically ages 9-10. It is one of the sheets on 4-PS4-2, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does The Path Light Takes 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 The Path Light Takes 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 The Path Light Takes free to print and photocopy?
