Transum's Three Way Challenge

As the title suggests there are exactly three different ways to complete the nine levels of this challenge. Simply changing the order in which the digits are multiplied together is not recognised as a different way.

This activity may be a good way to practise using your knowledge of prime factors and combining those factors in different ways to produce the three solutions required.

Please let us all know how your students get on with this activity by sharing your observations in the white comment box below.

You can earn a Transum trophy for each level you complete.

Here on the Transum website there are many interactive strategy games for you to try. Click on the button below to see our collection.

Strategy GamesThere are also hundreds of mathematical Lesson Starters on Transum. They are suitable for a range of ages and abilities and can be adapted to provide a quick 'settler' or developed into a whole lesson.

The solutions to this and other Transum puzzles, exercises and activities are available here when you are signed in to your Transum subscription account. If you do not yet have an account and you are a teacher, tutor or parent you can apply for one here.

"Being able to find the prime factors of a number may help you with this activity. The list of prime factors is a list of the basic building blocks of the number and you can combine some of these prime factors to make the four factors required (determined by the available buttons). You also have a button with one on it which is not prime so that should be remembered when combining the prime factors."
