Happy Summer!

Alas, another year of schooling has come to an end. Hopefully it was a fruitful one for you, in which you chose to challenge yourself and expand your thinking and knowledge. See you next year!

Oh, and semester grades are now posted!

Happy summer :-)

Finals Week

Monday = one last session to go over the latest indications of your mastery levels.
Use this time wisely to help prepare yourself for the final exam.

Any online postings must be turned in MONDAY by the end of class (after that you won't have your computer anyways...)

TUESDAY (third period) and WEDNESDAY (7th period) = FINALS
Any remaining math homeworks, etc. must be turned in at the START of the period designated for your final. No notebook turned in at that time = zero. Sorry, no exceptions, this is the longest I can give you!

Dead Week! (Finals are next week)

This week is all about mastery:

flesh out your self-evaluations (more copies below), and make sure to get credit for your completed assignments.

Chapter 12

You have a set of investigations regarding volume and surface area to complete (4 pages - click below if you need more copies)



Then, pick 10 questions from each section for homework (12.1-12.7)

That's it!

We'll review a bit during these last days of class, and perhaps continue our talks about why geometry matters (it's more than just a grade)...

11.2 11.3 11.4 11.5 11.6

11.2 Areas of Regular Polygons
Interesting Reading - basically, add up the triangles!

11.3 Perimeters and Areas of Similar Figures
Scale Factors! (S.F.)
Perimeter of Big Shape = Perimeter of Small * S.F. PB = PS*SF
Area of Big Shape = Area of Small * SF * SF Ab = As*SF^2
Can you guess the relationship for volumes?

11.4 Circumference and Arc Length
π = C/d ~ 3.14 (Remember the rolling CDs?)
C = πd = 2πr
For ArcLengths, just take the ratio of the arc versus the circle (°/360)
ArcLength = (°/360)*C = (°/360)*πd = (°/360)*2πr

11.5 Areas of CIrcles and sectors
Just like with arcs, except now we're doing area
A = πr^2
Area of sector = (°/360)*πr^2

11.6 Geometric Probability
(ummm, can you say ratios?)

Monday 4/27

Period 7 – Geometry (10th graders)
Students please separate into FIVE groups of up to four, and have each group sit at a table – there needs to be FIVE groups.

Assign each group a number (1,2,3,4,5)

Each group must prepare whiteboard(s) that demonstrate how to solve the problems associated with their chapter section (determined by the group numbers assigned above) in the Chapter 10 review (pp.650-652)

Group 1 does 10.1, Group 2 does 10.2, etc.

When 20 minutes remain, each group should present their answers, photobooth and post their whiteboards to the class discussion page.

Thank you!

Interior and Exterior Angles in a Polygon (~Chapter 11.1)

Ch.11.1 - We have some notes on how to find the number of interior degress in a n-gon
and some notes on the how to find the measure of an angle in a regular n-gon
and we did a little project demonstrating how the exterior angles in a convex n-gon always add up to 360°

HW - Problems 1,3,4,5,6,7,13,36,58,67
OR fasten in the exterior angles project and write up a claim based on your evidence with detailed reasoning

interior degrees = (n-2)180
regular interior angle = (n-2)(180)/n
exterior degrees = 360
exterior regular angle = 360/n


Popsicle Stix Bridge

Build a bridge out of standard popsicle sticks (from Michael's)

The Parameters:
You can have a partner
Must span 24 inches
100 (or less) stix
Only Elmers Glue and/or Rubber Cement
Decorations CANNOT add structural support
DO NOT TOUCH other people's bridges

The Scoring Rubric:
70% if it Spans and holds the bucket
+1% for every 100g added to the bucket
more than 3kg = extra credit!

Congrats to JW and TR for their winning bridge design! It held 50kg --> 110 pounds!
(That's a big basket, two bowling balls, every mass in the class, and three Algebra books too!)

Week 12 - AIMS Testing

Mon - Happy Chavez Day!

Tue - P.3 = 10.2, P.7 = Chat about AIMS Stuph

Wed - AIMS Math

Thu - AIMS Science

Fri - Phix it Phriday

Week 11

This week we'll be finishing chapter 9 and introducing Chapter 10.1

Friday is test/phix it day. Make sure to turn in your academic goal sheet to your first hour instructor(s).

Week 10 Details

Welcome back from break!

Mon - Time for Trig, we learned about the ratios between the sides of a right triangle, specifically sohcahtoa (do you remember what it means?) and we practiced using them to find missing sides of triangles. 9.5 was assigned

Tue - Ok, so now we know how to use the sine, cosine, and tangent of angles to find sides, but can we use sides of triangles to figure out the missing angles (of course!) So we learned how to get the calculator to find the inverse sin, cos, and tan. 9.6 was assigned

Wed - Late start, hope you got great mileage out of the Resume workshop, summer school programs, and College Depot presentations!

Thu - Mr. Chapman is at the robotics competition, sophomores have an AIMS review packet to complete, juniors should work on their homework. Sophomores who finish their packets and juniors who complete at least 30 min of solid work can use the remainder of class to challenge people in online BLOKUS (or just keep working!)

Fri - same as Thursday, work hard, get things done, have a great weekend, and I'll see you on Monday.

Spring Break

Quarter Grades are posted, hope you earned your goal!

Homework is to have fun and rest up.

-------------------------------------------
For those looking to get ahead:
Keep going in Chapter 9 (10, 11, 12)
Start thinking about a final project that shows your mastery of geometry

Week 9 - Last week of the QUARTER!


Please ensure that you've turned in everything up through Ch.8, postings for Ch.9.1-9.4 and the Mousetrap Car/Paper Tower/Origami Mobile Project (8 origamis, on a hanging mobile)

Mon - 9.3 Classifying Triangles Using Pythag

Tue - 9.4 Special Right Triangles

Wed - Phinish up the quarter

Thu - Phix it Phriday (a little early this week ;-)

Fri - Breaking it down to Geometry...

Week 8 (2/23-27)

Happy AIMS week to everyone!

Mon - P.3 will start section 9.1, P.7 Mr. Chapman is off-campus, so take some time to:
1) do the bellwork quiz (see picture below)
2) check your grades
3) Finish old work & bring online posting up to date
4) CLEAN THE ROOM! Chairs can be left down as there is a meeting this afternoon in the room.

Tue/Wed = AIMS, so I'll only see you once

Thu = 9.2 - Pythagorean Theorem
See here for some Pythagorean Triples

Fri = Phix it Phriday
