3D Shape: A vertex is a corner. Name:
‘Vertices’ is the plural of ‘vertex’
and means more than one corner.

2D Shape is flat.
Something is symmetrical when it
is the same on both sides. A
shape has symmetry if a line
drawn down (vertical) or across
(horizontal) the middle shows that

HOW CONCLUSION
A prism has two ends that are the Prisms and pyramids:
same shape and size. It has flat
sides.
Put a ring around the shapes that
are not prisms.
Write the name of the shape and
say whether it is a prism, a
pyramid or neither.

HOW CONCLUSION
Name the shapes in these
tessellating tile patterns
a. Hexagon
b. Square, triangle
Symmetry: If a shape can be
folded in half exactly onto itself
along a line, then that is a line of
symmetry.
There is a vertical
line of symmetry
in the shape.
There is a horizontal
line of symmetry in
the shape.
There are also
diagonal lines of
symmetry.

Nets of 3D shapes: A net of a 3D
shape is what it looks like if it is
opened out flat.
If you cut along the edges you
can open it up to make a flat
shape. This flat shape is called a
net.

- A shape has rotational
symmetry when it can be rotated
and it still looks the same.
- The order of rotational symmetry
is the number of times the shape
looks the same in one full turn.
