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 2 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.

3-5-ETS1-1
NameDate
Sort each one into criterion or constraint.
1.Sort each one: Criterion: what success means or Constraint: what limits you?
Sort: The bank must stop 90 out of 100 homes flooding, The device must send a message in under ten seconds, It must be carried by one person, No mains electricity may be used
Criterion: what success meansConstraint: what limits you
2.Sort each one: Criterion: what success means or Constraint: what limits you?
Sort: The alarm must be heard from the far gate, The budget is ten pounds, You have two afternoons to build and test it, The shelter must stay standing in a strong wind
Criterion: what success meansConstraint: what limits you
3.Sort each one: Criterion: what success means or Constraint: what limits you?
Sort: The light must be visible at fifty metres, It must be built from recycled materials only, The model must convert one energy form into another, Nothing may be screwed into the wall
Criterion: what success meansConstraint: what limits you
