Judging designs against criteria
Evaluate design ideas and finished solutions against criteria — personal preferences or given, co-developed or agreed criteria — including sustainability (e.g. uses reused or recycled materials, can be taken apart, uses little energy), and suggest improvements
Lesson
Set out your lesson
“Criteria define success; constraints limit resources; preferences say what we like. Reused paper is one sustainability check, not proof of the best environmental choice overall. Safety: Use only light pencils and paper; no sharp cutting or tipped furniture. Stop: End after checking one model. No added tape, heavier loads or sharp tools.”
Bring to the table
- Two reused paper sheets, pencil and ruler
- One wooden pencil to hold; stable flat work surface
Extra for the adult
Worked example. Illustrative evaluation: a channel retains the pencil during the defined 1 cm slide. Its footprint is 12 cm by 8 cm. It uses reused paper and unfolds intact. It meets those four local checks. A colour preference is not evidence of better retention or strength.
Optional challenge. Explain a trade-off if a wider base meets stability needs but fails the size limit.
What to notice. Keep both tables and the sketches. Note adult folding, measuring or suggested ratings.

Check understanding
- Judge their own finished design by saying what they like about it, whether it works for its purpose and whether it used materials wisely (e.g. reused boxes, little waste)
- Evaluate two design ideas against all the criteria, including at least one sustainability criterion, using a simple rating table
- Evaluate their finished solution against the criteria and suggest one change to make it work better or be more sustainable
“After building something like a model or a bird feeder, can your child say how well it works, what they like about it and whether they used materials wisely — and what they'd change?”
