Two Socrative tasks done in class today…these were meant to remind you of some key topics from the past few months that will reappear on the term test in about two weeks.
In-Class Assignment was done. Operating with polynomials, just like the work we were doing last week. Expect another one later this week (likely Friday).
Homework: Start refreshing for the term test.
New from yesterday/today:
pg.119-121, #1,2
pg.138 , #1,2,5
pg.140,-141 #1,5,9.
Download the “Socrative student” app for iOS or Android devices (free in the ‘App Store’ or ‘Google Play’).
Since technology is now creeping into every aspect of our lives, and especially the lives of young people, grade 9 students will be making use of handheld devices in class-for specific, closely monitored purposes.
We will be periodically using personal web devices (cell phone, iPod touch, etc) in class to conduct quick polls, assignments/practice quizzes and group exercises through the web based app, Socrative. Although many students do have such devices, it can’t be expected that all students have one with them at school; for that reason, these activities can be done via the classroom computers as well. Although there are hopes of doing so in the future, it is not yet my intention to use such tasks as marks for reporting purposes.
Privacy Concerns: No personal information is collected on students; in fact only their first name and last initial will even be entered in the data that I will see. Even the information entered by me (as a teacher and moderator) is minimal and does not associate me with our school, community or even city.
The use of the above mentioned devices during my class does not mean there is a change in school policy-it is still the expectation that devices are at the very least, turned off and out of sight throughout the common areas of the building and other classrooms unless given explicit permission from a teacher.
Please feel free to contact me with any concerns.
Corrections to yesterdays congruent triangles assignment. (see below).
Completed #13-24 on own…handed in as assignment.
Weekend homework:
pg.119-120, #3, 7 and 8(convince me, not a classmate), 9 and try #10… || means parallel.
Complete area problems from yesterday in class… see posted notes on Documents page.
Further practice with adding/subtracting polynomials (WATCH YOUR SIGNS!)
Then (for weekend homework):
pg 328-330, #9, 11, 13, 17, 23
pg. 343-345, #9,10, 12,13, 23
Further practice working with polynomials (multiplying, adding, subtracting, area problems).
Notes from class will be posted below soon.
Homework will resume soon; but, for now, questions from class should be done over and compared to given solutions as practice. Quick in-class task using cell phone or wifi device. Please bring to class if you have one. Don’t worry if you don’t have one though, the classroom computers will work just fine.
Homework will be assigned over the weekend.
Expect a small assignment in class on Monday and another one later in the week. Test should be Tuesday, 27 November…details to follow!
Practice identifying unique and congruent triangles (with reasons). Small assignment done at the end of class. See below for notes from today’s class. Photos will be posted soon.
No homework assigned. Don’t worry…the homework will resume soon! 🙂
Full class taken to review the homework (was part of the discovery from yesterday in class, pg.114-115 #1-4.
Discussion on ‘if…then’ / deductive reasoning and it’s applications.
See Documents page for board shots from today.
Breaking from the ‘front to back’ order in the text book. We’ll be working from chapter 7 and 3 over the next few weeks.
Today: further practice with distributive property. (Scalar times monomials, binomials and longer polynomials, monomials times all and binomials times all). Brief discussion of FOIL (they’ll see this next year, but it’s used to keep track of the distributive property with two binomials being multiplied.
See Documents page for notes/images from today.
