Real life plans and elevations - match the house plans to the images. Not as easy as it looks! There are two sets included here, one easier and one harder.
When was the last time you actually used a plan or elevation to teach this topic? This is a real life task based on real life house plans, great for getting students to discuss their geometrical reasoning and measurements.
Excellent extension task although I thought it needed some amendment so that pupils aren't flicking through lots of pages. I put four of the pictures on the board and presented the corresponding plans on an individual handout which worked really well.
