Treasure Island 

by

Robert Louis Stevenson

 

'What?' I hear you cry, 'does Treasure Island have to do with Maths?' 

Well quite a lot really.

For Year 6 we based finding Captain Flint's treasure and cannon shots from one pirate ship to another on ANGLES.

ANGLES???? What is an angle?

Angles

An angle measures the amount of turn

Names of Angles

As the Angle Increases, the Name Changes:

types of angle

Type of Angle Description
Acute Angle an angle that is less than 90°
Right Angle an angle that is 90° exactly
Obtuse Angle an angle that is greater than 90° but
less than 180°
Straight Angle an angle that is 180° exactly
Reflex Angle an angle that is greater than 180°

 

We used a protractor and our knowledge of the different sizes of angles to estimate, measure and record where the treasure and cannon balls would hit. 

Take a look a Captain Flint, aboard the Cleopas, modelling how to find the treasure and cannon balls using a protractor.
