Use your addition and subtraction skills, combined with some strategic thinking, to beat your partner at this game.
This activity is based on data in the book 'If the World Were a Village'. How will you represent your chosen data for maximum effect?
There are six numbers written in five different scripts. Can you sort out which is which?
On a digital 24 hour clock, at certain times, all the digits are consecutive. How many times like this are there between midnight and 7 a.m.?
What is the greatest number of counters you can place on the grid below without four of them lying at the corners of a square?
These clocks have been reflected in a mirror. What times do they say?
Place the numbers from 1 to 9 in the squares below so that the difference between joined squares is odd. How many different ways can you do this?
This big box multiplies anything that goes inside it by the same number. If you know the numbers that come out, what multiplication might be going on in the box?
This 100 square jigsaw is written in code. It starts with 1 and ends with 100. Can you build it up?
What happens when you add the digits of a number then multiply the result by 2 and you keep doing this? You could try for different numbers and different rules.
Take a look at these data collected by children in 1986 as part of the Domesday Project. What do they tell you? What do you think about the way they are presented?
Looking at the Olympic Medal table, can you see how the data is organised? Could the results be presented differently to give another nation the top place?
Look at some of the results from the Olympic Games in the past. How do you compare if you try some similar activities?
In this game the winner is the first to make the total 37. Is this a fair game?
These clocks have only one hand, but can you work out what time they are showing from the information?
What does the overlap of these two shapes look like? Try picturing it in your head and then use some cut-out shapes to test your prediction.
What shape is the overlap when you slide one of these shapes half way across another? Can you picture it in your head? Use the interactivity to check your visualisation.
On a digital clock showing 24 hour time, over a whole day, how many times does a 5 appear? Is it the same number for a 12 hour clock over a whole day?
An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.
