• This starter taught the children that things don't always happen on the first try - so you will have to try again and have patience.

• Nick, Waipahu Intermediate

• Is there any other way of doing this apart from trial and error?

[Transum: Hello Nick. It really depends on the given totals that are generated when the page loads. Some totals make the puzzle easier than others. Can I suggest that a more manageable puzzle is Latin Square and you can choose the level most suitable for your class.]
• Transum,
•
• Following on from Nick's comment above I have adjusted this Starter so that the puzzle you first see is one that minimises the amount of 'trial and error' required to solve it. This makes it easier than a randomly generated puzzle. However I have included a button to generate a random puzzle for those who enjoy a challenge. Good Luck!
