Pyramids and Prisms in the Real World
Different parts of a shape

Task 2: With Teacher: Attributes of Shape
Collect a 3D shape,
 First student places their object into a hoop.
 Second Student places their object into the hoop if it shares an attribute i.e vertices, faces, edges, regularity, volume, surface area, base area, pyramid, prism, shape of base, shape of faces, flat or curved surfaces, solid construction, open construction, hollow construction, mass. They tell the others what attribute their objects share.
 Each student then places their object into the hoop if their object also shares that attribute.
 Once all of the students have had a go, the students collect their object and the next student places their object into the hoop.
Task 3: Investigating Eulers Rule
What we are learning today  We are learning about Euler's Rule, a mathematical formula that is used to prove a prism or pyramid is a polyhedron.
In geometry, a polyhedron is simply a threedimensional solid which consists of a collection of polygons, usually joined at their edges. The word derives from the Greek poly (many) plus the IndoEuropean hedron (seat).

Task 4: Firing up the brain
Please play the games below with your sound turned off!
Prisms and Pyramids
Prisms: A prism is a 3D shape. Two parallel faces are the same polygon and all other faces are rectangles.
A cylinder is NOT a prism! 

Pyramid  A pyramid is a 3D shape of which the base is a polygon (Triangle, square, octagon etc.) and all the other faces are triangles. 

The triangles meet at a point (apex), which is the vertex
furthermost from the base polygon.
The name of the pyramid usually comes from its base shape i.e. Triangular Pyramid
A cone is NOT a pyramid.

TASK 1 Modelling  Cross Sections of Pyramids
Work in Pairs, choose a partner that will help you learn!
In your pair, use modelling clay to create a pyramid AND a prism of your choice (example shapes are available from the teacher).
Photograph your models, and insert them into your keynote of definitions of shapes and attributes. Make sure you properly name your shape, and whether it is a pyramid or a prism. If you are unsure of the 3D shape  ASK 3 before me.
Make a prediction, what do you think it will look like if we sliced the model in half? Draw what the shape will look like, Photograph it and save into your keynote.
Under teacher direction  Slice your model in half. Was your prediction correct? Photograph and record into your keynote
NET TOWN
The senior block is going to create a city scape, using nets to construct 3D buildings.
We will have some nets to hand out, however we encourage you to seek out and create your own nets (see link below)
Before you construct your 3D shape, you need to decorate your net to look like a city building  windows, doors, signage, colours etc.
Extension  Can you connect a prism to a pyramid to create roofs, and other marvellous buildings?

Investigation  Prisms and Pyramids
Investigate Euler's rule further, create a table like the one above in your binder book, and sketch out a series of different polyhedrons (prisms or pyramids).
Extension ideas  Some examples (but not limited to.)
 Include Euler's rule and use it on your constructions
 Investigate these special 3D shapes  tetrahedron, dodecahedron, toros, sphere, cylinder. How do they differ from prisms and pyramids? Can you find examples in the real world?
 Amaze the teachers  light up your Minecraft construction and combine various prisms, pyramids and 3D shapes.
