Introduction |
|
These activities are designed
to be viewed on a 17-inch screen and with a resolution of 1024
x 768 pixels because some windows show measurements in centimetres and
millimetres that, when viewed with another configuration, won't correspond
with reality; and the size of some windows can even be too big.
Students should
have a pencil and a piece of paper to do calculations and deductions of
the formulas used in these activities.
After checking the
activities, it is a good idea for students to share ideas.
- To recognise the different solids of revolution in the objects in our surroundings.
-
To know the net of the cylinder and of the cone.
- To deduce and know the cylinder, cone and sphere area formulae.
- To apply these formulae when calculating the areas of these solids.
- To deduce and know the cylinder, cone and sphere volume formulae.
- To apply these formulae when calculating the volumes of these solids.
- To get into the habit of writing down the corresponding measurement unit in the outcome of an exercise.
