**Task Name : **Index Laws Card Game |
**Task Level : **J (Year 9) |

**Semester : **1 |
**Topic :**Multiples and Indices |
**VC Strand : **Real Numbers; Patterns & Algebra |

**Web Address : **http://maths.crusoecollege.vic.edu.au/rnJ |

**Equipment Needed : **Stiff cardboard to make the cards; scissors |

**Victorian Curriculum outcome : **Apply index laws to numerical expressions with integer indices; Extend and apply the index laws to variables, using positive integer indices and the zero index |

**Task description : **Students use the index laws to make a concentration style card game. Students should use 24 cards, meaning there are 12 equations they need to show. Only four bases may be used so that the player can find the matching pairs based purely on the bases. All four index laws should be used in creating the cards, and each pair should involve working with either negative indices or variable indices. |

**Assessment options : **Photograph of the cards |

**Teacher notes : **Get the students to play each otherâ€™s games for practice. |
