As Mary wasn't at school today, her teacher decided to send her the homework by text message using his old mobile phone. Unfortunately the teacher did not know how to use the predictive text facility so the wrong words were sent. Can you figure out the correct answers? Predictive Text entry, allows you to enter text by pressing only one key per letter. As you enter a word, the phone will automatically compare all of the possible letter combinations against a built in dictionary of words, and determine which word you intended to type. When it guesses incorrectly, you will get the type of result seen here. Other words have been substituted for the ones we want.

but on the other hand decimly it will be a 3 being a 4x4=16.
• 5th Class, Cloghroe National School, Co. Cork, Ireland
•
• This was good fun, but quite difficult. It took a quarter of an hour for most of the class to get the answer. It was well worth doing.
• P6/7 St Elizabeth,
•
• Fantastic! P6/7 loved the problem and once we understood the concept we found it really easy!
• Transum,
•
• Just wondering for how many more years will this starter be relevant. The photograph is an old phone and the newer phones don’t require predictive text as they provide a full keyboard. The comments above suggest that you like this starter but happy to replace it with something more up to date if you think pupils won’t relate to this.
• Y5, Willen
•
• We got half if it but now we are stuck - where are the answers?

[Transum: Keep trying Year 5. There answers are available to teachers and appear lower down this page when the teacher is signed in.]

 The Righteous Men is also available as an audio book.
