# Learning By Topic KS2: David Walliams and Mathematics

How many millions are equal to 1 billion?

Show the place value for each number in  1, 254, 367, 981.

Create a number code for the alphabet (e.g. a =1 b=2 be a bit more adventurous than this example) write your theme words using this code – can anyone crack your codes?!

Now ask an adult to write some addition, subtraction, multiplication and division sums in this code. Can you decode these and then solve them?

Look up the average salary of a doctor. How many years would they have to work to earn as much as Billionaire Boy (one billion pounds)?!

What would you buy if you had one billion pounds and had to spend all of it in one month!?! Make a shopping list and find out how much each item would cost – what is the total?!

The Ice Monster sold 110 000 copies in the first five days after its release! At £9.88 per book how much money was made in the first 5 days of sales?

For one week, read every day for an hour, record how many pages you read in that hour. Plot this information on a bar graph. Now interpret the data: on which day did you read the most amount of pages? On which day did you read the least amount of pages? What other information can be determined from the data?

Upper KS2: From the above data can you find the mean, median, range and mode?

Extension: can you convert and record the total amount of time spent reading from hours to minutes and then possibly even seconds?
