Again, the language here. Finding a percentage change. It can easily be confused with changing by a percentage. I need to have a sit down and think about how I talk about the language here, and how specific I am. Especially with our EAL learners.

Percentage of amount [Non calc]
Download the PowerPoint/Worksheet here
Lots of stuff here.
I use the ‘work out 10% first’ method.
I stole the mind map idea from Don Steward, who came up with the best tasks.
I’ve done another Blooket, too.

Percentage of amounts [calc]
Download the PowerPoint/Worksheet here
I’m going through and updating my percentages PowerPoints so that I have all of percentages done and ticked off. Here’s the percentage of amounts with a calculator one, I’ll upload percentage of amounts without a calculator next. I like to separate the two skills.
I also make a blooket. You can find that here. I’m currently loving blooket. It’s basically like Kahoot, but with games. I think the games are really well devised, and it’s great for getting kids doing simple, procedural questions. I also like how the best mathematician doesn’t always win. I know that seems counter intuitive, but often with Kahoot, the same person wins every time. Which can demotivate some. It’s also great for getting them doing work over a longer period of time than Kahoot is.
Again, I’ve actually been really busy updating all sorts of resources. Use the menu at the top to see what I’ve got.

Reverse Percentages
Again, simple. There’s example problem pairs covering discounts/price increases and three exercises of questions.
Not much more to say.
Again, if you want to get in contact about collating these somewhere where people will actually see them, hit me up on Twitter. I’m @ticktockmaths.

New resources : Decimal Time, Percentage Increase without a calculator, Two or half?
We’re back learning from home this week, and it’s given me a bit of impetus to clean up some old resources and make some new ones. Everything here is quite short and simple, but hopefully it saves someone a bit of time.
Decimal Time
Download the PowerPoint and worksheet here.
I’ve recently found out you can save a PowerPoint as filename.gif. So cool! I found when I was doing compound measures that my students needed extra practice on this. It was holding them back from answering speed questions correctly. So here is a quick lesson on converting time.
I delivered this digitally, sharing my screen over Google Classroom and using my iPad pencil to write my modelling over the example problem pairs. I added the PDF of the questions into the Google Classroom and gave them ten minutes to complete the questions either in their books or digitally on the PDF.
We then came back after these ten minutes to go through the answers. I then made sure they could not leave the lesson until they had handed in their work on Google Classroom. This a routine I go through pretty regularly and I find it works really well. It means I get a log of what they’ve done and there’s accountability as their work is checked then and there.
Percentage Increase and Decrease [Non Calc]

Really simple lesson. Really simple questions. However, I also added a little slide of 9 multiple choice questions. I like this format. It did require over 150 animations, though!
It was really nice to show this and go through the questions one-by-one discussing why I had chosen the wrong answers. I am not 100% happy with the question set, though. If you’ve got any good suggestions for questions, please tweet me @ticktockmaths.
Starter : Two or a half
A really simple starter. I made this because I did a Kahoot online with my year 10s and a large proportion of them got question 11 wrong. They knew how to do speed, but they instinctively didn’t really want to get a half as an answer. I made this as a starter for the following lesson to really hammer home the point.
Quite a productive week. It’s easy to make stuff when you don’t put yourself under pressure to make 1000 slide behemoths, but just simple, quick and easy resources that don’t reinvent the wheel.
