Y5/6C Usain Bolt challenges

Usain Bolt can run the 100m in a world record time of 9.58 seconds. In maths we took this measurement and wondered what we could do in the time Bolt can run the hundred metres (ten seconds). We needed to each undertake a maths challenge and a challenge of our own choice. Some examples of the challenges were:

How many even numbers can you write down in ten seconds?
How many square numbers can you write down in ten seconds?
How many times you can bounce a ball on a cricket bat in ten seconds?
How many times you can bounce a ball on a tennis racket?
How many dominoes can you stand up in ten seconds?
How many times you can bounce a ball in ten seconds?

These results were collected and then displayed as frequency tables and graphs. We had lots of fun undertaking the challenges.
