In this feature, we have chosen some resources from the Special Numbers pathway onĀ wild.maths.org.

In some senses, all numbers are special, though some are perhaps given more attention than others... We hope you'll discover that there's a lot more to averages, fractions and square numbers than you might initially think!

Here's how you can send your solutions to these problems.

Five numbers added together in pairs produce: 0, 2, 4, 4, 6, 8, 9, 11, 13, 15 What are the five numbers?

15 = 7 + 8 and 10 = 1 + 2 + 3 + 4. Can you say which numbers can be expressed as the sum of two or more consecutive integers?

Three people chose this as a favourite problem. It is the sort of problem that needs thinking time - but once the connection is made it gives access to many similar ideas.
