Y6 – 03.07.20 – Maths Challenge 5

Hi Year 6, I hope you are all safe and well. It was lovely to see all of you at our Leavers Assembly even though it was sad saying goodbye.

This week you have been set a variety of different math’s challenges that many of you have enjoyed. Today, I will continue with these challenges.

Task 1

This is a problem solving game. Please complete the task by following the link and blog your score.

Task 2

For this task you will need to answer the following questions.

There are a number of ways the digits 2,5,7,8 can be placed in a subtraction sum like the one below:


57 - 28 = 29 as a column subtraction


In this example, the answer is 29.

Can you rearrange the four digits to find all the (positive) answers it is possible to make? The answers must be positive.

 



Here are two follow-up questions you might like to consider:

  • Can you work out which four digits you need to start with to be able to get all the possible answers 7,9,11,13,18,22,29 and 31?
     
  • Can you show that, if we’re only allowed to use consecutive digits (e.g. 5,6,7,8), 31 is the largest possible answer and 7 is the smallest?
