  13. Stay In Your Groups • We are going to learn how to play: Blackjack 1

  14. Rules • The same rules as blackjack but instead of trying to reach 21 you need to get to 1. • Use the cards you are given to try and add up to 1. • Each card has a fraction with a value between 0 and 1. • It is possible to go over the value of 1. This means that you cannot win that round.

  15. Adding Fractions Review • Add fractions together by only adding the numerators! • The Denominators must be the same! • Remember what you do to the denominator you must do to the numerator! • You can change fractions by finding equivalent fractions! • For instance ½ is the same as 2/4 which is the same as 3/6 and so on.

  16. Practice • ½ +3/4 = • 2/3 + 1/3 = • 3/8 + 1/3= • 6/10 + 1/5 =

  17. Let’s Play a Practice Round! • Choose one person in your group to be the dealer. • They have the cards and will deal you out two cards each. • Go around one by one and either get another card from the dealer or stay with the cards you have. • Keep track of how many times you win!

  18. Play! Do not forget to Have fun!
