# Please May I Have Years 2 - 6

A game for two players, each with a calculator.

### Preparation

This game is special because it emphasises the use of good manners when you ask for something. An adult might be needed to help introduce the game.
• One calculator each (there's one on your phone)
• Write the title of this challenge and today's date on a fresh page in your maths journal.

### How To Play Please May I Have

 The game makes a point of correctly using place value language. For example, instead of saying the number in the photo is three-five-two, players would say three hundred and fifty-two. The game is played by two (2) players, each with their own calculator. Players secretly enter a number in a chosen range, say 100 - 999. For example the player in the photo has entered 352 (three hundred and fifty-two). Players take turns to ask for a digit that they hope will be on the other player's screen. If one of the opponent's digits is guessed the opponent must state the value of the digit. Example Suppose Player A has 352 on the screen and Player B asks: Please may I have a 5? Player A must answer: Yes, you may have 5 tens.
At this point Player A would subtract 50 from his/her total and Player B would add 50 to his/hers.
Then it would be Player A's turn to ask.

But, suppose Player A has 352 on the screen and Player B asks:

Please may I have a 9?
Sorry, I don't have one.
At this point both screens stay the same. Then it would be Player A's turn to ask.

Keep playing until one player either reaches a screen above 999 (nine hundred and ninety-nine) and wins,
or a screen below 100 and loses.

Special Rule

• If a player has more than one of the digits requested, they may give any one without revealing that they have others.

Have fun exploring Please May I Have.

We suggest it is used at least three (3) times a week for about fifteen (15) minutes over several weeks.

Make the game more challenging, especially for older learners, by asking questions like:

• What happens if ... we start with a range from 750 to 1,250?
• What happens if ... we start with a range from 0·1 to 10?
What would your screen look like if it was showing a number smaller than 0·1?
