## Activity: “noughts and crosses” and module test

26. Let us play “Noughts and Crosses”!

You need a friend and a rectangle with decimal numbers as in the example.

You may also write your own decimal numbers in the blocks.

• Player 1 chooses any number on the rectangle and must say what number ÷ or × by 10, 100 or 1 000 will give that number.

e.g. 2,5 : 25 ÷ 10 = 2,5 or

0,025 ´ 100 = 2,5

 0,9 2,2 0,45 1,4 2,5 0,08 0,91 0,17 0,007 3,6 0,168 0,024 0,14 0,98 0,016 4,1
• Player 2 checks with the calculator.
• If player 1 is correct, he marks his block with a x or o.
• Take turns until one of the players is the first one to get 4 x’s or o’s in a row. (horizontal, vertical or diagonal).

what's the big difference between prejudice and discrimination?
A prejudiced person may not act on their attitude.  Therefore, someone can be prejudiced towards a certain group but not discriminate against them.  Also, prejudice includes all three components of an attitude (affective, behavioral and cognitive), whereas discrimination just involves behavior
