Charlie has made a Magic V with five consecutive numbers:

It is a Magic V because each 'arm' has the same total.

Alison drew this magic V:

Charlie said "That's really just the same Magic V as mine!"

What do you think Charlie meant?

There are six more Magic Vs that are the same as Charlie's - can you find them all?

**Can you find all the possible Magic Vs that use the numbers $1$ to $5$ and are different from Charlie's?**

How can you be sure you have found them all?

**What happens if you use the numbers from $2$ to $6$? Or from $3$ to $7$? Or $4$ to $8\dots$?**

Here is a spreadsheet to help you investigate Magic Vs made from five consecutive numbers.

**Can you describe an efficient strategy to find all Magic Vs for any given set of numbers?**

Can you use your strategy to find all the possible Magic Vs that use the numbers $987, 988, 989, 990, 991$?

**Can you find a Magic V where each arm has a total of 60? Or**** 1000? Or...?**

**Can you find more than one?**

**Can you find a Magic V for any arm total? **

Charlie and Alison drew some more letters, to see if they could make them magic - that is, using consecutive numbers to make equal arm totals.

Magic L? | Magic N? | Magic W? |

Investigate some of these Magic Letters in the same way that you explored Magic Vs.
