Different ways of Saying Numbers- Reversi

Different ways of saying numbers reversi

Instructions for teachers

Cut up one set of cards per group of two to four students so that each card has two boxes with the two versions of the number together, i.e. don’t cut between “one million” and “a million”. Get rid of any cards which are too difficult or not useful for your students, but make sure that there are still at least twelve cards.

Deal out the cards and ask the students to fold them so that the two versions of the numbers are on opposite sides of the card. It doesn’t matter which side is up at the beginning of the game.

There are several ways of playing the game, all of which involve students trying to say what is on the other side of the card, leaving them the other way up if their guess is correct. The next person can then do the same with the same cards, with different cards or with a mix of new and old cards. The different games are:

• Students choose any cards they like to guess the other side of each time, with highest total number of correct guesses (added up over the length of the game) winning
• Students choose any cards they like each time, with the longest uninterrupted string of correct guesses during the game (e.g. ten cards in a row one time) winning
• Students put all the cards into a column and have to start from the bottom of the column each time, with the person who gets furthest up the column winning (like climbing and falling down a ladder)

After finishing the game, the students can test each other on different ways of saying the same numbers, and then say similar numbers for other students to say other ways.
