What Counts, and What Limits is a free printable Grade 3 to Grade 5 science worksheet on defining a design problem with criteria and constraints, aligned to Common Core standard 3-5-ETS1-1. It prints 3 questions with an answer key on its own sheet of paper, in 25 versions that each ask different questions, so no two pupils in the class work from the same page. Print it from the browser or download it as a PDF — no account, no email.
Set 4 of 25 · the same problems every time you open this link.
Set 1 has all 25 in a single PDF. All 25 sets ask different questions.

NameDate
Sort each one into criterion or constraint.
1.Sort each one: Criterion: what success means or Constraint: what limits you?
Sort: The light must be visible at fifty metres, Nothing may be screwed into the wall, It must be carried by one person, The bank must stop 90 out of 100 homes flooding
Criterion: what success meansConstraint: what limits you
2.Sort each one: Criterion: what success means or Constraint: what limits you?
Sort: No mains electricity may be used, The shelter must stay standing in a strong wind, It must be built from recycled materials only, The device must send a message in under ten seconds
Criterion: what success meansConstraint: what limits you
3.Sort each one: Criterion: what success means or Constraint: what limits you?
Sort: You have two afternoons to build and test it, The budget is ten pounds, The model must convert one energy form into another, The alarm must be heard from the far gate
