10/11/2020 | For our first lesson, we will introduce pooled testing in the context of coronavirus. [Show less] |

10/18/2020 | We will be introduced to modular math. We completed pages 1-6 of the handout. [Show less] |

10/25/2020 | We will be continuing the second half of the handout on modular math. We will also learn modular math applications, such as checksums. [Show less] |

11/1/2020 | We will finish up our review on modular math, learning how to subtract and divide in modular math as well as learning how to prove divisibility rules with modular math. [Show less] |

11/8/2020 | We will be exploring an ancient Egyptian technique of splitting fractions into their unit parts. We completed pages 1-16. [Show less] |

11/15/2020 | We will continue our exploration of Egyptian fractions (pages 17-24). Homework is pages 25-26. [Show less] |

11/22/2020 | To conclude our exploration of Egyptian Fraction Representation, we will complete the Egyptian Fractions part 1 handout and begin Egyptian Fractions part 2. Pages 6-8 EFR part 2 are assigned as homework. [Show less] |

12/6/2020 | We will look a method to prove mathematical hypotheses: proof by induction. [Show less] |

12/13/2020 | We will continue to explore proof by induction and introduce proof by contradiction. *Last class of fall quarter, Happy Holidays! [Show less] |

1/10/2021 | Suppose we break a stick into three pieces randomly. What are the chances the resulting pieces will form a triangle? [Show less] |

1/17/2021 | We will continue and complete our packet on breaking sticks. In which scenario are we most likely able to form a triangle from our broken sticks? [Show less] |

1/24/2021 | This week we will learn how to convert between fractions and decimals, while also exploring the properties of terminating and non-terminating decimals. [Show less] |

1/31/2021 | We will continue to explore terminating and non-terminating decimals. WHY do decimals have these properties? How can we write non-terminating decimals as fractions? [Show less] |

2/7/2021 | We will write and define sequences and numbers through explicit and recursive definitions. We will also explore arithmetic sequences and how we can generalize the sum of n-terms in the sequence. [Show less] |

2/14/2021 | [Show less] |

2/21/2021 | We will continue our work on arithmetic sequences, then transition to learning about arithmetic series. [Show less] |

2/28/2021 | We will introduce geometric sequences and explore how using geometric series can help us convert non-terminating decimals to fractions. [Show less] |

3/7/2021 | Today, we introduce combinatorics: the mathematics of counting. [Show less] |

3/14/2021 | We will complete the combinatorics worksheet from last week. Furthermore, we will explore what happens if the order of the items in our list matters. [Show less] |

4/4/2021 | Can you move the earth with a lever? Today's math circle lesson will require creativity, physics, and a little intuition to balance levers. [Show less] |

4/11/2021 | We will refresh our minds on combinations and permutations from before spring break, and we will also begin to explore probability. [Show less] |

4/18/2021 | To test our knowledge of combinatorics that we learned over the past few weeks, we will go over 4 tough problems. [Show less] |
