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]

Download the PowerPoint and the worksheet here.

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

Download the PowerPoint

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.

The Cosine Rule

Download the resources here.

I did the Sine Rule ages ago but never got around to doing cosine rule stuff. I think because the Mathspad activities are so good!

I didn’t go much into labelling the sides (which maybe I need to in future) or putting it all together. I think I’m going to do a resource called ‘Trigonometry : Putting it all together’ where several rules are used. Maybe with some exam questions and a bit of goal free stuff.

No posts for the next two weeks. I’m off on holiday.

Things I Think I Think…3

I aplogise to the Hull City blog Amber Nectar, who I kind of nicked this post format off.

  1. I’m really into ‘fill in the gaps’ activities recently. I love how they develop thinking forward and backwards. I love this worksheet on time calculations which I used recently. I went down really well and sparked great conversations. Love this kinda stuff. (Although for some reason TES won’t let me review the resource and give it 5 stars).
  2. Talking of TES, I’ve updated my resources on Measuring Bearings, Calculating Bearings, Expanding Brackets and the Sine Rule and uploaded them on there. I’ve corrected mistakes, sorted out some formatting and freshened things up.
    I’m still unsure about all this. I don’t think my resources should be on their own website. I understand that we have far too many resource websites to check, but at the same time TES is pretty rubbish. It’s annoying to update a resource if I see an error and track changes, and it’s interface and search isn’t great.
    Plus there’s all this paid junk flooding the listings meaning that stuff never gets seen. The other thing is that I struggle to get feedback there. I don’t know if stuff is not getting downloaded because it’s rubbish or because people don’t see it.
    I’d love to have a platform with some quality control that I could submit resources to, but I realise that’s probably a pipedream considering how much such a thing would cost to run.
    Tweet at me if you want to discuss any of this because I think there’s potential in connecting things.
    I know it’s kinda pathetically attention seeking but I’ve been making resources for 10 years now and I feel a lot of it just gets lost in the mix. Which kinda puts me off doing it.
  3. Talking about bearings… I did my measuring Bearings lessons the other day, and we’d lost a load of half protractors. So I used this template and printed them out on tracing paper. A game changer! It worked brilliantly. Just make sure you change the printer output setting to ‘transparent’ or whatever similar setting you are offered.
  4. I’ve been thinking a lot about books recently. I’ve got some colleagues who are really on it with books and end up with classes that have awesome books. It’s something that I really want to work on next year (I’m sure I’ve said this before). I think it requires quite a lot of follow through and effort, though. Definitely something to think about.
  5. I love this Tweet. Lots to think about in regards to the language that we use.
