'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?
An angle measures the amount of turn
|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.
