Thursday 4/27

Today for our minimum day we finished our intro to scientific notation today with the last part of Lesson 13.4.

Homework: Student Assignments workbook 13.4

Wednesday 4/26

Today we learned how to use scientific notation to represent both really large and really small numbers in Lesson 13.4. We'll do some more work with scientific notation tomorrow.

Here's a great visualization of the kinds of things for which we'd need scientific notation to measure or count. Notice the base 10 power in the lower right corner?

Homework: Textbook pages 714-715 (#2-4) & page 717

Tuesday 4/25

Today we finished our look at exponent properties with a look at negative and zero exponents in Lesson 13.3.

This now completes all six of the exponent rules that you need to memorize and be able to use to solve and simplify a variety of problems. You'll find all six in the graphic on this post. Study, study, study; practice, practice, practice!

• Product Rule of Powers
• Quotient Rule of Powers
• Power to a Power Rule
• Negative Exponent Rule
• One Power Rule
• Zero Power Rule

Monday 4/24

We had a Boss Battle then worked in MATHia/Desmos for the rest of the period.

Homework: MATHia practice

Friday 4/21

We visited the math fair today. I hope you had a lot of fun looking at all the projects, and reflecting on just how much you've grown since last year. 

Here is this weeks Extra Credit:

Thursday 4/20

Today we investigated multiplying and dividing powers in Lesson 13.2. Don't forget to complete any unfinished classwork from today. Problems 2, 3, and 4 were assigned in class.

Homework: Textbook pages 700-701

Wednesday 4/19

We learned about powers and exponents today in Lesson 13.1.

Homework: Student Assignments workbook 13.1

Tuesday 4/18

Many of us were away today performing at Knott's Berry Farm with band, orchestra, or choir. Those that remained worked on MATHia/Desmos with Mr. Medina.

MATHia and Desmos due tonight! Those of you who were away performing all day, I need Desmos turned in as soon as you have access to a computer, and MATHia I will push back one extra day before I record yours.

Homework: MATHia practice

Monday 4/17

Tough test to close out Chapters 11 & 12 today. If you needed a bit more time to finish up, you can come in either before or after school or at lunch on Wednesday. The same also goes for the common assessment, let's try to get everything we need done by Wednesday so we can look forward to our next subjects.

Remember, MATHia/Desmos grades will be due by Tuesday night! You'll get all day in class on it tomorrow.

Friday 4/14

We took Common Assessment #5 in class today, then worked in MATHia and Desmos afterwards.

Homework: MATHia practice

Thursday 4/13

Today we finished up our look at systems of linear equations with Lesson 12.2.

We'll put your new knowledge and skills to the test on Common Assessment #5 tomorrow, followed by our Chapters 11 & 12 Test on Monday. Don't forget to put in a little extra time studying over the next few days.

Homework: Student Assignments workbook 12.2

Wednesday 4/12

Today we finished Lesson 12.1, all about writing equations from context and solving them using linear combination.

Homework: Student Assignments workbook 12.1

Tuesday 4/11

We discovered our third and final method to solve systems of linear equations today: solving by using linear combinations (also sometimes called the elimination method) in Lesson 12.1.

It takes a little bit of practice to get this technique down, but I think you'll find it quite helpful to quickly and easily find the solution of a linear system of equations.

Be sure to use the example on page 652 to help you with your homework tonight!

Homework: Solving Systems with Linear Combinations worksheet

Monday 4/10

We had a MATHia/Desmos day today, along with our first foray into dealing with Bosses in Class Craft! I'm hoping this can be something we can have weekly for review, so be prepared! I enjoy seeing the development of everyone's characters as we advance through the class.





This Friday we are going to have the next Common Assessment, so I have decided to extend the deadline for MATHia/Desmos to Monday night. This gives a bit more time to make sure we have everything done when we need to since we won't have all of Friday to work on it. Keep up the good work everyone!

Homework: MATHia practice

Friday 4/7

Sorry for all of the technological issues Friday. Hopefully things will be figured out when we get back, have a great weekend, everyone.

It's late, so I'll accept this until Thursday, but here is this week's extra credit:

We've been studying scenarios that can be modeled using two linear equations recently. Your objective, should you choose to accept it, is to create your own scenario that can be represented, and hopefully solved, using a system of linear equations.

We've looked at systems where two items are decreasing (reef tanks), two items are increasing (savings accounts), one item is increasing and one is decreasing (income vs cost), and even scenarios where we're tracking the combination to two variables (adults and children, attendance vs admission).

Complete each of the tasks below and post all your content to the comments section on this post. Be creative! Impress us!

1. Define your problem scenario. What's happening? What do we need to determine?
2. Write two or more equations to represent the scenario. Define your variables.
3. Solve the system via substitution.
4. Explain what the solution means in terms of the problem scenario.
5. Post your scenario here in the comments of this post. Feel free to include both text and/or photos of written work or graphs you may have created to show your solution.

Thursday 4/6

Today we wrapped up our look at solving systems via substitution with the last of Lesson 11.4.

Homework: Student Assignments workbook 11.4

Wednesday 4/5

We spent another day working with solving systems of linear equations by substitution, this time shifting our attention towards context problems and systems that model them with Lesson 11.3, Problem 3 and Lesson 11.4 Problem 1, Part 1.

Be sure to put in an additional 10 minutes each night studying these new concepts and/or reviewing any homework or class work errors. This is tough stuff and requires extra effort to master.

Homework: Student Assignments workbook 11.3

Tuesday 4/4

Today we introduced ourselves to a second method to solve systems of linear equations: Substitution!

We're going to be working with this method all week, so you'll have plenty of time to get comfortable with the ins and outs.

Today was a good intro. Tonight's homework will be a good chance to test out your new skills.

Homework: Textbook page 630

Monday 4/3

Welcome to April!

We worked in MATHia/Desmos today. MATHia and Desmos grades will be calculated on Friday, April 14. Make sure we are staying on pace to get everything done!
