A Mathematics Lesson Starter Of The Day


Topics: Starter | Data Handling | Live Data | Statistics | Time

  • M Darwin, The McAuley Catholic High School
  • Live data the numbers change too quickly even though they repeat, it would be better if they were on longer - about 8 to 10 seconds.
  • F. Ricciardi, The Charter School, South London
  • I agree numbers change a too quickly. Not even enough time for them to jot them down before they change. Great idea though!!
  • Colin MacKay., Carnoustie High School.
  • This was fun, challenging, confusing, and a good mixture of questions, and just as well it was a 24hour clock.
  • Daisy And Conner, Scotland
  • Bonjour We loved this Maths Starter YOU ROCK TRANSUM.
  • Ole And Daisy, Year 6, Beckley School
  • We think Las Vegas and Delhi have the biggest time gap.
  • 6PJ, Epsom
  • Please lengthen the time the temperatures/times are displayed before they change.
  • Mr T, Kent, UK
  • Is anyone going to do anything about the numbers changing so quickly.
    Surely it can't be that difficult.
    Questions are brilliant, thanks.
  • Transum,
  • For all those who mentioned that the numbers change a too quickly there is now a new version with analogue clocks above. Click on the button under the Starter to see the alternative (original) version of this Starter in which the numbers change too fast for many people.
  • Peter,
  • I think the USA and the Middle East has the largest time differences.
  • 6r, Lacey Gardens
  • Nairobi
    St Petersburgh.
  • 5R, Cavendish Close Juniors
  • Auckland, New Zealand and Vancouver, Canada.

The temperature and times given are current (live) data so we are unable to provide answers to all of the questions.

1. Which city is currently the warmest?
Probably Bangkok but it depends on the current conditions.

3. What is the range of temperatures?
Take the coldest temperature from the warmest.

5. What is the time difference between Birmingham and Bangkok?.
Seven hours in the winter and six hours in the summer (daylight saving time)

7. It takes 11 hours to fly from Bangkok to Birmingham. If you take off at midday from Bangkok, what time will you arrive in Birmingham (local time)?
4pm. Though there is currently no direct flight from Bangkok to Birmingham!

2. What is the mean (average) temperature of these four cities?
Add up the temperatures then divide by four.

4. Estimate the temperatures inside and outside your classroom right now.
The inside temperature is probably about 23o C (if you are feeling comfortable).

6. What will be the time in Boston when it is half past midnight in Brisbane?
09:30 though this might be affected at different times of the year by daylight saving time. Does anyone know?

8. Can you guess which two cities in the world have the biggest time difference?
Depending on the definition of a city! Let us know what you think here.

Below is an Amazon search box and some items chosen and recommended by Transum Mathematics to get you started.

Have you read Craig's book yet?

Craig Barton must surely be the voice of Mathematics teachers in the UK. His wonderful podcasts interviewing the industry experts have culminated in this wonderful book. As Craig says: "I genuinely believe I have never taught mathematics better, and my students have never learned more. I just wish I had known all of this twelve years ago..." more...

"How I wish I’d taught maths' is an extraordinary and important book. Part guide to research, part memoir, part survival handbook, it’s a wonderfully accessible guide to the latest research on teaching mathematics, presented in a disarmingly honest and readable way. I know of no other book that presents as much usable research evidence on the dos and don’ts of mathematics teaching in such a clear and practical way. No matter how long you have been doing it, if you teach mathematics—from primary school to university—this book is for you." Dylan Wiliam, Emeritus Professor of Educational Assessment, UCL.

Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...

Texas Instruments Nspire Calculator

This handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TI-Nspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TI-Nspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others.

For the young people in your life it is a great investment. Bought as a gift for a special occasion but useful for many years to come as the young person turns into an A-level candidate then works their way through university. more...

iPad Air

The analytics show that more and more people are accessing Transum Mathematics via an iPad as it is so portable and responsive. The iPad has so many other uses in addition to solving Transum's puzzles and challenges and it would make an excellent gift for anyone.

You have to hold iPad Air to believe it. It’s just 7.5 millimeters thin and weighs just one pound. The stunning Retina display sits inside thinner bezels, so all you see is your content. And an incredible amount of power lies inside the sleek enclosure. So you can do so much more. With so much less. more...
