Maths
takes shape We need to be aware of the
shapes and spaces all around us. They affect how we dress, arrange the
furniture, decorate our homes and build the world around us!
Orange peel
Peel an orange (or a satsuma) then do the following.
Divide it into segments.
Count the segments.
Eat one segment. That's one segment out of
how many?
Eat half of all the segments. How many segments
was that?
What other fruits have segments?
From
3D to 2D
Get an empty cereal box (a three-dimensional shape), and carefully take
it apart at the seams by undoing the edges. Flatten the box out and see
its shape as a two-dimensional shape. This is called a 'net'.
Look at the nets of other box shapes.
Shape
of the day
Choose a shape that you can look out for when you go to the shops. You might
choose triangles, squares, cubes, pyramids and so on. How many shapes can
you see in your shopping trolley?
Imagine
this
Close your eyes and imagine that in front of you there is a cube. Can you
see it in your mind?
What shape is one side (or face) of a cube?
(It's a square)
How many sides (or faces) has it got? Remember
to keep your eyes closed!
How many corners has it got?
How many edges
has it got? Seeing the shapes in your head is very important in maths.
Try this with other solid shapes.
