This week, Primary 5 have been extending their knowledge of 3D shapes. In Primary 4, we learned that 2D shapes could make 3D nets and ‘skeletons’. So, we decided to use our knowledge of shape properties to create some more. Here are some of the shapes we created:
We did run into a problem – although we had the correct number of faces, edges and vertices, we couldn’t make our shapes join accurately. So, we thought about why this might be. We realised how important it is to measure shape edges and re-made our designs using accurate measurements. This meant our ‘skeletons’ would join together easily and we could add tabs to our nets to glue them.
Next week, we are going to be looking at angles. Check in with us to see what we have learned.
Until next time…
Primary 5 & Miss M 🙂
