Friday 4/29

We took a practice interim assessment in class today. Nice work!

Here is this week's extra credit:

Thursday 4/28

We finished our intro to scientific notation today with the last part of Lesson 13.4.

Homework: Student Assignments workbook 13.4

Wednesday 4/27

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)

Wednesday HW Solutions: Student Assignments workbook 13.3 answer key

Tuesday 4/26

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 Rule
• Zero Rule

Monday 4/25

We started our next Desmos project, worked in MATHia, talked a bit about the timeline for the next several weeks, looked at exceptional waterfall projects, and reviewed last Thursday's homework in class today.

Homework: MATHia practice

Friday 4/22

Tough test to close out the week. Nice work, everyone. Enjoy some downtime this weekend; we'll be back at it with powers next week.

If you'd like more time to finish your test, you may come in on Monday before school, during lunch, or after school.

Don't forget that MATHia and Desmos are due tonight!

Here is this week's extra credit:

Thursday 4/21

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.

Tomorrow we'll be taking our Chapters 11 and 12 test. Be sure to study your pre-tests, chapter summaries, and old class work / homework to arrive prepared.

Homework: Student Assignments workbook 13.2

Wednesday HW Solutions: Student Assignments workbook 13.1 answer key

Wednesday 4/20

We learned about powers and exponents today in Lesson 13.1.

Homework: Student Assignments workbook 13.1

Tuesday 4/19

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

Have you met your goals for the week?

Homework: MATHia practice

Monday 4/18

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

Homework: MATHia practice

Friday 4/15

Here is this week's extra credit:

Thursday 4/14

Today you 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 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 HW Solutions: Student Assignments workbook 12.1 answer key

Wednesday 4/13

I was out today, but in my absence you finished up Lesson 12.1, further developing your skills in writing systems from a context and solving them using linear combinations.

Homework: Student Assignments workbook 12.1

Tuesday HW Solutions: Linear Combinations worksheet answer key

Tuesday 4/12

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!

Also, we'll be taking Common Assessment #5 on Monday, April 18th. A study guide has been posted in the Document Locker.

Homework: Solving Systems with Linear Combinations worksheet

Monday 4/11

Today was a MATHia/Desmos day for us, the first of this new grading period. I hope you were able to get off to a great start! MATHia progress is available at the link above.

Homework: MATHia practice

Thursday HW Solutions: Student Assignments workbook 11.4 answer key

Friday 4/8

Have a great weekend, everyone.

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 Google+ Community. 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. Solve the system graphically.
5. Explain what the solution means in terms of the problem scenario.
6. Post text, written work, graphs, photos, and/or videos to Google+.

Thursday 4/7

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 HW Solutions: Student Assignments workbook 11.3 answer key

Wednesday 4/6

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 4/5

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 4/4

We worked in MATHia and Desmos today. MATHia/Desmos grades will be calculated on Friday. Are you on pace to meet your goals?

Homework: MATHia practice

Friday 4/1

Great first week with systems of equations, everyone! Have a wonderful weekend.
