Stretch

A scale plan measures 6 cm by 4 cm at 1:100. Find the real floor area in m².

Reveal a worked check after attempting

6 m by 4 m, so 24 m².

Deep challenge

Two solids have identical front and side elevations. Must their plans be identical? Explain with an example.

Reveal a worked check after attempting

No. Different depth arrangements can produce the same elevations; a plan reveals the arrangement from above.

What Went Well (WWW)

I selected the correct geometric fact, theorem, formula or transformation and used a clear diagram with appropriate labels and units.

Even Better If (EBI)

I will name the fact or theorem, show the substitution or construction step and check whether the size, direction and units of the result are reasonable.
