First day of the Second Semester

Today Mr. Maksymchuk told us about the new rules, and the wierd noises that there have been videos of. Then we talked about what we would do with computers, we are only allowed to use them when he askes us to, 'cause we were really bad. THEN, he asked us, about if it was worth his time to record him talking about a certain thing we are doing in math or science. He will only record if one person out of us all wants him to record him talking on and on and on and on.................. Then we did some stuff on similarity. Then Mr. Maksymchuk took Marty's phone and mine.

Math

Today in math, we did mental math 30 and found the average of all of them, then we did that assessment, and then some people worked on accelerated math or the chapter test on page 262.

today in math, we did mental math. Mr. Maksymchuk went around the classroom checking the questions that were homework. pg 246/247 7,8,15,16,17. The people who are finished the those questions are doing a practice assessment that is not for marks.

Scribe post for Nov. 29

Today we started off doing mental math, then we got a talking to about yesterdays assignment. Today we are to finish yesterdays assignment. Then if you get done you can start on the mid-unit review.

Scribe Post

Yesterday we were assigned to do...

• 5.1 Page 214-215 Qu. 5-8, 11-13 & 15
• 5.2 Page 222-223 Qu. 6-9, 11-15

All need to be done by tomorrow for homework.


Notes done today...

Today in math class we did mental math 21 and talked about definitions amd wemt over the questions

Details for FRIDAY!

Details For Fridays Assessment:

Priority order:

1: Finish assigned questions from each section

2: Finish chapter review (1-27) pg 87-89

3: practice test pg 90 (1-8) ALL!

4: Accelerated Math (SEE MR. MAKSYMCHUK!)

today in math we went over last night homework.

Below is a checklist for math and is ALL supposed to be done.


Checklist for Math:
1. Textbook 1.1
2. Textbook 1.2
3. Textbook "Mid-Unit Review" Pg. 21 Qu.1-11
4. Textbook 1.3
5. Photo Assignment.... (below)
Photo Assignment Checklist:
1. Title (Name of the Object)
2. Photo (*If web guaranteed, provide URL as credit)
3. Explicit- formula for surface area
4. Explicit- formula for volume
5. Calculator Link for surface area
6. Calculator Link
7. LABELS! (math 9, display name, savolume)

Shapes Assignment

The object we chose is a rectangular prism.

The formula for surface area is- 2(d(h+w)+hw)                d- depth
                                                                                                                                     h-height
The formula for volume is- dhw                                                    w-width

http://www.csgnetwork.com/surfareacalc.html  -  is a calculator for surface area

http://www.csgnetwork.com/volumecalc.html   - is a calculator for volume

These calculators are for all types of 3d shapes

Hemi-Sphere

Volume of Hemisphere = (2/3)πr³
Total Surface Area(TSA) of Hemisphere = 3πr²

cylinder

surface area formula: 2pir^2+2pirh

volume: v=pir^2h

this calculator link helps you find the surface area and volume of a cylinder.

Today in class we found out that we are going to have an assessment on Friday, Sept 30. It is on integers, fractions, and rationals. We are working on a booklet that  Mr. Maksymchuk gave us in the beginning of class, this booklet is based on what the assessment will be on. We also watched part of a video about how "new math" is not as good as the "old math", we didnt finish in class because Morganne kept talking hahaha. Mr. Maksymchuk told us if we want to watch the video we have to watch it on our own time.

this is a site where you can learn how to do fractions and integers but u can also see what else u will learn in grade 9 math.

LOLHAHAHA:D

this is a website that you can use so help you with useing fractions or integers.http://www.xpmath.com/forums/arcade.php?categoryid=3

This is a site for farctions and integers and alot of other math units. THis is a fun way to learn. http://www.arcademicskillbuilders.com/

The First Scribe on the blog

We started off with mental math, then went over the scribing directions, then he did a recording and a smartboard thing on Natural numbers - real numbers - integers - rational numbers - irrational numbers - whole numbers. Haha Maksymchuck paused the recording at the three minuite mark and missed a whole bunch of stuff. We learned that an unreal number is _i_.

A Challenge....

Create your first post. Distinguish yourself. Be creative. Introduce yourself. Be polite. Use correct punctuation, spelling, grammar, etc.

Remember, you're expected to use school-appropriate language, and follow the internet acceptable use policy....


Welcome to the online entity that is our class. Enjoy learning from and with each other...
