## Status message

Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan (link is external) on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform (link is external).

## Algebraic Proof Lesson

The students will get their first introduction to proofs. Since we are dealing with algebraic proofs, this is the first time students will be challenged to justify every step of solving an equation. They must start to think WHY along with HOW.

Resource Type:
Content Area:

## Conditional Statements

Students will identify, write, and analyze the truth value of a conditional statement. They will first learn what the inverse, converse, and contrapositive of a conditional statement is and by the end will be able to write all 3 of these. There will be a variety of math related examples along with real life examples.

Resource Type:
Content Area:

## Pairs of Angles

The students will be introduced to adjacent + vertical angles along with linear pairs. They will be asked to solve problem based off these angle relationships. Additionally, they will find the complement and supplement of an angle.

Resource Type:
Content Area:

## Measuring and Constructing Segments

Students will be using the segment addition postulate and the midpoint theorem to find the lengths of various segments. This will include simple drawings as well as more challenging word problems. These postulates and theorems will be used the entire year in Geometry.

Resource Type:
Content Area:

## Understanding Points, Lines, and Planes

Students will define a point, line, ray, segment, and plane as it relates to Geometry concepts they will be exploring the rest of the year. These definitions will become essential once students start writing proofs and determining when to use certain notation. This is a building block for the entire year.

Causes of the War

Total War

America and the War

The Flu Pandemic

The Paris Peace Conference

## CPCTC Lesson - Congruent Parts of Congurent Triangle

In this lesson, students will learn how to use the CPCTC theorem (Congruent Parts of Congruent Triangles are Congruent) in order to complete a proof. They will first use one of the 5 triangle congruence theorems (SSS, SAS, AAS, ASA, HL) in order to use the CPCTC. It is a great lesson putting together everything they have learned thus far in the unit.

Resource Type:
Content Area:

## Two-Party Debate

Students will culminate the unit on political parties with a debate on whether America should continue on with a two-party system or move to a multi-party system. To incorporate technology and an international aspect to the debate you will be participating with a classroom from Canada via Skype, a country that has a multi-party system.
