Introduction to big data

A detailed presentation from Ben Houghton, data scientist at Barclays PLC. It is good introduction to Big Data and the three Vs (volume, variety and velocity). Other topics covered are machine learning and its use in fraud detection, legal and data privacy challenges and technology bottle necks caused by...

Evaluating statements about radicals

This lesson develops concepts relating to radicals. In particular, students will enhance their understanding of:

  • Use the properties of exponents, including rational exponents and manipulate algebraic statements involving radicals.
  • Discriminate between equations and identities.
    In this...

Meteorite investigators

In this lesson, students will investigate some of the meteorites and associated rocks in the loan box. They will test them for magnetism, do a visual analysis and measure their mass to calculate the densities of their items. This activity is particularly geared towards getting students to estimate the volume of the...

Trigonometric functions

This short task contains two questions on applying trigonometry.

The topics covered are:

  • Linking sine, cosine and tangent
  • Using Pythagoras to determine a length in a triangle and then give the tangent of an angle in surd form
