Happy Halloween everyone!

My gift to you: Pumpkin Pi!

We worked in MATHia today. Don't forget that the current Functions & Linear Models module is due next Friday.

Be safe tonight!

Homework: MATHia practice

Friday 10/28

I was out today, but in my absence you worked in MATHia X, and are hopefully nearing the finish line on this current module. Two weeks to go!

Here is this week's extra credit:

Thursday 10/27

Today we took a quick look at perfect squares.

After that, many of you finished your Chapter 3 test. Those that were already done spent the rest of the period doing more work with Marblesides (see Monday's post) or working to catch-up in MATHia X.

Speaking of MATHia, are you on pace to finish the Functions & Linear Models module by November 11th? Since today is a minimum day it's a perfect opportunity to spend some extra time with MATHia X at home if you're a bit behind. You should have 14 or more workspaces complete by tomorrow.

Homework: Perfect Squares worksheet

Wednesday HW Solutions: Chapter 4 Pre-Test answer key

Wednesday 10/26

We took our Chapter 3 test in class today. I hope it went really well for you, perhaps even so well that you exited the classroom dancing!!

Homework: Chapter 4 Pre-Test

Tuesday 10/25

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

We'll be taking our Chapter 3 test tomorrow. Happy studying!!

Homework: Equations in Slope-Intercept Form worksheet (all the even problems tonight)

Monday 10/24

We worked through an awesome Desmos Marbleslides activity today to experiment with slopes and intercepts of linear equations. If you'd like to spend a bit more time on the challenge problems tonight, feel free to jump right in at student.desmos.com.

• Period 4: 2NM88

Also, a reminder that we'll be taking our Chapter 3 test on Wednesday. Happy studying!

Homework: MATHia practice

Friday 10/21

Don't forget next week is Red Ribbon Week! Don't forget to show your drug-free pride by participating in our spirit week activities.

• Monday: Sweats Day
• Tuesday: Crazy Day
• Wednesday: College & Career Day
• Thursday: Decade Day
• Friday: Wear Red Day

School dress code still applies (including hats).

Thursday HW Solutions: Slope-Intercept Equations answer key (odd)

Here is this week's extra credit:

Thursday 10/20

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.

Parents: Have your child 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 (just the odd problems tonight)

Wednesday 10/19

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 (Problem 6)

Tuesday HW Solutions: Determining Y-Intercepts answer key

Tuesday 10/18

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 the rest tomorrow.

Homework: Determining Y-Intercepts worksheet

Monday 10/17

Today we worked in MATHia X and went over one of the more challenging problems from last week's common assessment.

Homework: MATHia practice

Friday 10/14

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

Here is this week's extra credit:

Thursday 10/13

We prepped for tomorrow's Common Assessment #2 today with a rather involved warm-up, then spent the rest of the class period investigating the rate of change from an equation with an awesome Desmos activity!

If you didn't finish the activity in class today, be sure to do so tonight at home. Head to student.desmos.com, then type in your class code: S3PHS

A study guide for tomorrow's common assessment is available in the Document Locker.

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

Wednesday HW Solutions: Slope from Equations worksheet answer key

Wednesday 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

Tuesday HW Solutions: Rate of Change worksheet answer key

Tuesday 10/11

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: Rates of Change worksheet (Problems B & D)

Monday 10/10

We worked today in MATHia X.

I also shared that we'll be taking Common Assessment #2 on Friday. A study guide has been uploaded to the Document Locker.

Homework: MATHia practice

Friday 10/7

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



Here is this week's extra credit:

Thursday 10/6

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

Wednesday 10/5

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

Tuesday 10/4

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!

Homework: Textbook pages 153-154

Monday 10/3

You spent today working in MATHia X. The entire Functions and Linear Models module is due in a little over a month. Are you making good progress?
