Percentage of amounts: an introduction

I created this presentation to introduce finding a percentage of an amount to my lower ability Year 5 maths set. I was unable to find anything else online that demonstrated clearly what exactly an percentage of a number means and that didn't over-complicate the subject. There are plenty of visual examples to show how we find a percentage of an amount. The presentation clearly links percentages to fractions. It start by demonstrating percentages on a 100 square and progresses to using different numbers. Simple animations show how a number can be split into different fractions and percentages.
