Happy Halloween Everyone!

My gift to you, pumpkin pi:

Here is this week's extra credit:

Thursday 10/29

We reviewed the homework from Tuesday today (answers are posted on yesterday's blog post if you have some correcting to do tonight).

We also talked about perfect squares. Your job is to memorize all the perfect squares up through 15. They'll come in handy in upcoming lessons!

Homework: Finish the Perfect Squares worksheet

Wednesday HW Solutions: Chapter 4 Pre-Test answer key

Wednesday 10/28

I was at the district office all day, but in my absence you took the Chapter 3 test. I hope it went really well for you, perhaps even so well that you exited the classroom looking like this guy!!

Homework: Chapter 4 Pre-Test

Tuesday HW Solutions: Problem 2 worksheet answer key

Tuesday 10/27

We jumped into Chapter 4 today with Lesson 4.1 in class. We did problem 1 in groups and went over solutions together in class today.

Your homework is to do the Problem 2 worksheet to determine . . . will he catch him?

Here is the correct solutions for #4 on your homework tonight (in slope-intercept form):

y = 4/5x - 8

You'll need #4 to be correct in order to successfully complete the rest of the assignment.

Don't forget - you'll be taking your chapter 3 test tomorrow in class. Study well, and arrive prepared and confident!

Homework: Finish the Problem 2 worksheet

Monday 10/26

Today was a MATHia day. We passed back MATHia grades from the past two weeks, and got off to a good start for this next grading period. You should be wrapping up island 3 of MATHia.

We'll be taking our chapter 3 test on Wednesday this week. Good study tools are your chapter 3 pre-test, the chapter summary at the back of the textbook pages, your class work, and your homework assignments.

Homework: MATHia practice

Friday 10/23

Chapter 3 is complete. Nice work! We'll take our test on it next week. Perhaps now is a good time to begin studying . . .

Don't forget next week is Red Ribbon Week!

• Monday: Team up against drugs!
• Tuesday: Do the math - drugs just don't add up.
• Wednesday: We're too bright for drugs!
• Thursday: When you wish upon a star, there will be no drugs where you are.
• Friday: Wear red day!

School dress code still applies (including hats).

Here is this week's extra credit:

Thursday 10/22

Today we finished the second half of Lesson 3.6, which focused on equations in standard form.

If you get stuck your homework tonight (it's definitely a thinking assignment), remember you can use the Community to get some extra help.

Homework: Finish textbook pages 203-206 (#1-8, skip #2)

Wednesday HW Solutions: Equations in Slope-Intercept Form worksheet answer key

Wednesday 10/21

We learned three major things in the first half of Lesson 3.6 today:

• How to graph a function using slope-intercept form,
• How to write an equation in slope-intercept form given only the slope and a point, and
• How to write an equation in slope-intercept form given only two points

Tonight's homework focuses on the second two skills.

If you need some help on tonight's homework, check out the examples on pages 198 and 199 and the videos above! They'll show you exactly what to do with the info you have to determine the y-intercept and the slope. You can also post up where you need help in the Community.

Parents: After you child has reviewed the examples on those two pages, have them explain to you the process to find the equation of a line 1) given the slope and a point, and 2) given only two points. If they can explain their strategy in their own words, you know they're ready for their homework.

Only begin tonight's homework after reviewing the classwork from today. These skills definitely take practice!

Homework: Equations in Slope-Intercept Form worksheet

Tuesday 10/20

Today we finished Lesson 3.5 and can now determine the y-intercept from a graph, a table, a context, and an equation.

Parents: Ask your child to explain to you how to find the y-intercept in each of the four representations above. Have them show you an example of each in their textbook. If they can explain their process and their thinking, you know they've got it!

Homework: Textbook pages 192-194 "Talk the Talk" (#1-6)

Monday 10/19

We spent today in MATHia working towards our end-of-the week goals. Are you on pace to meet them by Friday?

You should be nearing completion of island 3, since we nearing the end of chapter 3. If you're not quite there, consider spending some extra time this week to get yourself back on track.

Homework: MATHia practice

Friday 10/16

Ten weeks and two common assessments down! Have a great weekend, everyone.

Here is this week's extra credit:

Thursday 10/15

Today we learned how to find the y-intercept in a graph, table, context, and equation in Lesson 3.5. We did the first half of the lesson, and will finish it next week.

We'll be taking Common Assessment #2 tomorrow. Be sure to study all of Chapter 2 tonight, and the first half of Chapter 3 (everything we've learned so far), so that you arrive fully prepared tomorrow. If you have any questions, post them up in the Community and we'll help you out!

Homework: Determining Y-Intercepts worksheet

Wednesday 10/14

I was at the district office all day, but in my absence you worked in MATHia.

Reminder: We'll be taking Common Assessment #2 on Friday. Your chapter 2 and 3 pre-tests, and your chapter 2 test all make great study tools! A study guide has been uploaded to the Document Locker to help you get ready.

Homework: MATHia practice

Tuesday 10/13

We finished our look at finding the rate of change / slope of an equation today in the second half of Lesson 3.4. We discovered that it's always a two step process:

1. Get the equation into
   y = mx + b format
2. The slope is the coefficient of x

We also did a Desmos activity to investigate the meaning of slope in graphs and equations. If you'd like to do/finish the activity at home, go to student.desmos.com and use class code we2s. Extra fun: have your parents try it!

Also, a reminder that we'll be taking Common Assessment #2 on Friday. A study guide has been uploaded to the Document Locker (linked in the toolbar above).

Homework: Textbook pages 179-180 (#3, 4, 5, 7)

Monday 10/12

Today we learned how to find the slope (also known as rate of change) from an equation in Lesson 3.4. We learned that when an equation is written in slope-intercept form, the coefficient in front of the variable x represents the slope. To find the slope, all we have to do is rewrite any equation in slope-intercept form!

Don't forget to check your class work with the answers linked above.

Homework: Slope from Equations Worksheet

Friday 10/9

And just like that, the first quarter of the school year is complete! Report cards will be carried home next Friday.

But first . . . the last MATHia grading period of this quarter ends tonight at midnight. Have you met your goals yet?

Here is this week's extra credit:

Thursday 10/8

Today we tackled Lesson 3.3, which focused our attention on finding the rate of change and unit rate from a context.

We learned that there's not a set formula or method to solving these - it's all about thinking critically, evaluating what you'd need to know to answer the question, and using the clues given to determine the rate.

Homework: Textbook pages 168-170 (#6, 7, 9, 10)

Wednesday 10/7

We finished our look at rates of change from a table today with the last part of Lesson 3.2. The focus today was on tables that may or may not represent linear functions, and what it takes to tell the difference.

Homework: Textbook pages 160-161

Tuesday 10/6

Today we continued our look at finding the rate of change and unit rate from a table with Lesson 3.2. We're now proficient with both informal and formal methods.

Sometimes, some students get tripped up not with the rate of change methods, but in adding and subtracting positive and negative numbers. If you need to brush up on those skills, use the daily practice links at the side to become an integer master!

Homework: Textbook pages 148-149

Monday 10/5

We spent today working in MATHia. The current MATHia grading period will close on Friday. Are you on track to meet your goals?

Homework: MATHia practice

Friday 10/2

Great job this week, everyone!

Here is this week's extra credit, with a twist:

Describe, in your own words, the process for finding the rate of change from a graph. To earn the extra credit, post your description to The Community for everyone to see!

Thursday 10/1

Today we learned how to find the rate of change from a table with Lesson 3.2. We learned both an informal method (arrows) and a formal method (y2 - y1) / (x2 - x1).

Be sure to practice the formal method on your homework tonight, as it's a more powerful way to determine a correct answer without error!
