I see that someone above has already posted about the mistake in 4a – can I just say that we had possibly the most beneficial and enjoyable reasoning and problem solving lesson trying to test and prove whether first 15cm was a possible perimeter, and then whether it was possible to have a rectilinear shape with an odd-length perimeter; the challenge moved to the staffroom at break time too, and we’re all very excited to have used our ‘prove it’ skills for a real purpose! Much more learning went on than was anticipated – thanks!!

Wow! As much as we endeavour to avoid any errors on our resources, however we are very glad to hear that this led to a teachable moment full of reasoning and problem solving 🙂 Thank you for letting us know. Louisa

Thank you for these resources they are great quality! I have noticed a mistake on answer 4a. the shape given cannot equal 15cm based on the left edge being 3cm and the right edge having a total length of 2cm. If it is a rectilinear shape then as far as I can work out the answer will always be even due to the corners having to meet in a right angle.

Hi Hannah, thank you for your feedback. I will pass this on to the resource creating team to look in to 🙂 Louisa

Hi,

This resource says perimeter of rectilinear shapes but when downloaded is the resources for perimeter of rectangles?

Thanks

Hi, can you try again now as when I’ve checked this, it downloads as Perimeter of Rectilinear Shapes. Many thanks, Sian 🙂

This is the wrong title for this lesson. This is area of rectangles and not rectilinear shapes. Please can you add the rectilinear shapes pack.
