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: Textbook page 709

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 (#2-4)

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

Homework: Read page 710; do page 708

Monday 4/24

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

Homework: MATHia practice

Friday 4/21

We visited the Math Fair today! I hope you all had fun looking at the projects and seeing some of the applications they found for what we do in class every day.

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: Textbook page 692 Talk the Talk

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 with Mr. Medina.

MATHia due tonight! Those of you who were away performing all day, I will push MATHia back one extra day before I record yours.

Homework: MATHia practice

Monday 4/17

Tough test to close out Chapters 11 & 12. 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 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 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.

Today seemed to go very well. I hope it cleared up this topic a bit for those of you who were still struggling. We were working very hard today as well, great job all around.

Homework: Textbook pages 659-661

Wednesday 4/12

Today we finished up Lesson 12.1, further developing your skills in writing systems from a context and solving them using linear combinations. Today was a much better day than yesterday, keep up the good work. I know this can be a difficult topic which is why we need as much practice as we can get.

Homework: Textbook page 654/Finish last nights worksheet.

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 made progress in MATHia today, while some of us explored a little bit more with Class Craft. We're having fun with our characters but make sure we are on progress to meet the MATHia deadline.

This Friday we actually have our next Common Assessment, so I have decided to extend the deadline for MATHia to Monday night. That gives us an extra weekend to get stuff done. Keep up the work everyone.

Homework: MATHia practice

Friday 4/7

Sorry for all of the technical issues on Friday everyone. Enjoy the weekend and I hope things will be figured out when we get back.

It's late but here is the extra credit for this week:

Thursday 4/6

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

Tonight's homework is tough, so please be sure to give it your best effort, care, and attention. We want you all to be substitution masters!

Homework: Textbook pages 635 #5a,b,c

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.

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: Textbook pages 631-632 (#2a-d)

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 today. MATHia grades will be calculated on Friday, April 14th. Some of us have had trouble getting stuff done by the due dates, be sure you are staying on track and managing your time to get everything we need done.

Homework: MATHia practice
