# Classroom Resources

This collection from Teachers TV features videos, covering a wide range of mathematics topics, which are intended to be shown in class. Often ideal for use as as a lesson starter, some show practical applications of mathematical principles which pose problems for students to solve. Areas covered include:

*algebra to solve real problems
*surface area of different shapes
*averages
*continuous data
*estimation
*nets
*ratio and proportion
*distance/time graphs
*equations
*golden ratio
*probability
