We learned about congruent triangles today in the first half of Lesson 8.2.

We discovered the difference between equal and congruent, and investigated how to write congruence statements and measure/length statements.

Homework: Textbook pages 439-440

Monday 1/30

Today we passed back the first MATHia X grades of second semester, then jumped back into MATHia and into our second Desmos project.

Remember to split your time between MATHia and Desmos to reach all your goals.

Homework: MATHia practice / Desmos project

Today we tackled reflections with the first half of Lesson 7.4. We'll finish the other half tomorrow.

We'll be taking our Chapter 7 test on Thursday, which will cover all three transformations that we've learned so far:

• Translations
• Rotations
• Reflections

Be sure to study lessons 7.1, 7.2, 7.3, and 7.4 to get yourself fully prepared.

Homework: Transformations worksheet

Monday 1/23

We worked in MATHia and Desmos today.

Reminder: the Geometric Transformations module and your Desmos House project are due on Friday.

Homework: MATHia practice

Friday 1/20

Congrats on finishing your 20th week! Have a great weekend, everyone.

Here is this week's extra credit:

Thursday 1/19

We finished our look at rotations today with the second half of Lesson 7.3.

We also learned how to use the Darth Vader in the City technique to rotate points and vertices about any point. This is going to come in very handy on our test next week!

Homework: Student Assignments workbook 7.3

Wednesday HW Solutions: Rotations worksheet answer key

Wednesday 1/18

Today we worked with rotations with the first part of Lesson 7.3. We'll finish the rest of the lesson tomorrow.

Homework: Rotations worksheet & finish any leftover class work (from either today or yesterday)

Tuesday 1/17

Today is class we explored the effects of our second kind of transformation, a rotation, with an awesome Desmos activity.

For those that were absent today, you'll need to complete the activity at home on your own. Head to student.desmos.com and type in the class code that goes with your period.

Period 1: WVARV

Period 2: W5AMT
Period 6: S3748

Homework: Play the Center of Rotation game at home with a parent or sibling.

Friday 1/13

Great first week back, everyone! For those absent today, we jumped into our first Desmos project. You should check with a classmate for details, so you can catch yourself up this weekend.

Thursday HW Solutions: Student Assignments 7.2 answer key

Here is this week's extra credit:

Thursday 1/12

We continued our work with translations today with a look at translating linear functions in Lesson 7.2.

We discovered that translating a linear function either vertically or horizontally will change the y-intercept, but will not change the slope in any way.

Wednesday 1/11

Since the laptop connections have been restored, we jumped back into MATHia today and started the Geometric Transformations module.

Homework: Compose a summary of Lesson 7.1. Be detailed and include all the new terms learned throughout the lesson.

Tuesday 1/10

We contained our look at translations today with the second half of Lesson 7.1.

Here's the Desmos tool we used for translations in class today: bit.ly/desmostranslations

Homework: Student Assignments workbook 7.1

Monday 1/9

We had some technical issues with our laptops today, so we jumped into translations with Lesson 7.1.

Here's the Ohio State Marching Band illustrating a translation for you. :-)

Parents: Ask your child to explain in their own words (and identify in their class work) the terms transformation, translation, congruent, image, and pre-image.
