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

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.
