**09/20**: Classwork: Math 9 Algebra baseline test | Classwork: Math 9 Geometry baseline test | Welcome Letter: Math 9 welcome letter to students and parents |

Homework assignment for Sep. 27 is to work on the remaining problems from the baseline review test and previous year's placement tests.

- Assigned on
**09/27**: Classwork: Algebra. Elements of mathematical logic. | Classwork: Geometry. Commensurate segments. | Homework: Assignment for Oct. 4. | - Assigned on
**10/4**: Algebra Classwork.: Elements of mathematical logic. | Geometry Classwork.: Thales proportionality theorem. Similarity | Homework: Homework assignment for Oct. 11 |

I pasted solutions of 3a and 3b from the last homework on the jamboard - you may do the rest. Please try to figure out a convenient way for you to use a jamboard, or any similar virtual board for working in class. For the new Algebra assignment on logic - please look through the handout. Do not pay attention to Math Induction - it will be our next topic.

**10/18**: Algebra Classwork: Mathematical Induction. Sequences. Progressions. | Geometry Classwork: Direct and Inverse theorems. Ceva theorem. | Homework: Assignment for October 25 |

You can skip the mathematical induction, sequences and progressions for now (Algebra problems 3-5) - we will do it next time. In geometry - please go over the proof of the generalized Pythagorean theorem (in geometry classwork handout - or just prove it yourself using the property of proportions that we considered in class!).

**10/25**: Classwork: Geometry. Similarity and homothety. | Homework: Homework assignment for Nov. 1. | - Assigned on
**11/1**: Classwork: Math Induction. Arithmetic and geometric mean. | Homework: Homework assignment for Nov. 8 |

In geometry assignment - please solve the problems using similarity and Thales theorem where appropriate; we will solve use these using Center of Mass later.

**11/8**: Algebra Classwork: Math Induction (contd). Eucleadean algorithm (rec) | Geometry Classwork: Geometry. Law of Lever. Method of mass points. | Homework: Assignment for Nov. 15 |

Since we did not cover the Geometry in class, you do not need to do the Geometry part of the homework.
