Percentages without a calculator, including percentage increases and decreases

I’ve been using Excel for over 20 years now and you will be amazed how superb it can be for teaching maths. This file is for teaching students how to work out any percentage of a quantity. There are scrollbars so you can select the starting quantity depending how easy or hard you want to make it. All of the answers are worked out automatically (that’s the beauty of Excel): you just need to click on the green ticks and they will be revealed. You can look at percentage increases and decreases too and there are some exam-style questions with answers provided too. Essentially, everything you need to teach your students about percentages, increases and decreases with all of the answers automatically worked out for you. Get ready to be blown away by the power of Excel. I also make sure my files are beautifully presented in order to capture the students’ attention right from the off. I have made a series of these so if you find this useful, please have a look at my other files.
