3D shapes - Pyramids and prisms

 Yesterday N got to the page in her maths book all about shapes, 3D shapes to be precise.  It was asking her to count how many faces were on each shape.  I know she is a more visual learner so this morning we made 3D shapes.

It only took two shapes and it all clicked, she is now happily drawing shapes all by herself she enjoyed it so much!

Here's how we done it:

To make a pyramid:

Make a square (we measured our sides as 6cm) remember to ensure all corners have 90 degree angles.

measure out 60 degree angles from each corner outwards to make 4 triangles the same size.

Add little tabs to the right side of each triangle.

score down all the lines...

using the tabs glue it together so it looks like the above!

We also made this triangular prism:

We made the rectange 10cm long and used 60 degree angles to make the triange.

Added some tabs again...

Then glued it together.

This was beneficial to N, I hope someone else out there can make use of it too.


  1. Thanks for this I have pinned it to my pinterest ready to use next maths lesson :)


    Love your idea, well done! This link might prove useful for printing out 3D SHAPES if you don't have time to make your own.Have fun!

    1. Thank you! I have now favourited that link! N really enjoys making things from scratch but I think HB will enjoy the printables. x

    1. Thank you! N enjoyed helping me use her protractor and measuring it all out. x
