Hello everyone! Its Megan J here, and this post is about what went on yesterday and the the day before. All in all, not much happened, but we had a fun work block for both the days.
On the second day (the 28th), we received our practice tests and our collaborative quizzes. For the practice tests, the answer key is in the back, and be sure to mark your it before you hand it in. If anyone was worried, there is no homework assigned for these nights, so have a nice relaxing evening!

What is UP my mathmatical amigos? It's yo pal Katie. How are ya'll doin' today? I'm letting my ego swell at the fabulous compliment Mrs. B gave us today. That's right! We're two-ply toilet paper, folks! Let that just soak in and relish in that praise. We're on a roll today! Today we covered how to solve those nasty problems that involve, not 1, not 2, but 2+ right angle triangles! Now before y'all panic and tell me, 'How the diddly dang heck am I supposed to do that?' Let me walk you through the steps. Okay, so the question is asking to find RQ. 1. This is the time where you take your metaphorical scissors and snip those two triangles in a half! 2. You're going to pick the Triangle with the most information and solve it for the side where it's connected to the other triangle. You're going to bridge that information to the OTHER SIDE! 3. Using the found length from the previous triangle, you'll bridge it over to the other one, and solve for RS. Then you simply add both lengths together and Congratulations! You found the answer! What should you take away from this: 1. Seperate the Triangles. 2. Find the Triangle with the most information and solve for the side that connects to the other triangle. 3. Bridge that information over and solve for the answer the problem tells you to find! Also, don't use thicc highlighters to highlight things. It's a bad idea, kids. Here are also some videos in case I missed something or need a little extra help understanding this weird topic.
February 22 2018!!! Hey everyone its Will with todays post! I will be reviewing what we learned on Thursday February 22nd in Math 10 Challenge! To start the class we went over the rules of applying trigonometric ratios, we were also given some handy tools to remember when we're solving our problems. Our main tools consist of: 1. Trigonometric ratios: sine, cosine, and tangent 2. Pythagorean theorom 3.Knowing that the sum of all angles is 180 degrees 4. Drawing correct diagrams 5. Your brain. Do not forget your brain!!! After we went over solving problems as a class, we had a small chat about how we as students can avoid stress and pressure in the modern school environment. One tool that we can use is called a replacement thought, this involves replacing a negative/stressful thoughts that can disrupt our learning in the classroom, so, what is a good example of a replacement thought? Well, it's honestly something that makes you happy, and focusing on the positive aspects of a somewhat negative situation. As an example for me personally I really love basketball, so I like to think about being on the court and having fun with my teammates when the stresses of school are effecting my learning. When we learn to replace negative aspects of situations with positives, we change our mindsets and become more productive learners. Ok, back to math, later in the class we later went over angles of elevation, and angles of depression, don't forget that the angles from angles of elevation and depression are always found from the horizontal. We then looked over the Z rule, and here is a video talking about what the Z rule means and how we can implement the rule into solving problems!!! This video shows the Z and the C rule for alternate angles. I hope this video and post was interesting and have a wonderful day!!! Hello everyone, Afaf (or Olaf) here! :) Tuesday, February 20: On Tuesday, Mrs. Hoffman gave us a visit to answer all of our deep n' burning questions on ~shudder~ course selections. Some of you may have felt: a) Nervous b) Afraid c) A bit of both! And that's ok, remember Mrs. Bjornson's advice on breathing in and out exercises it's always helpful to put yourself in check before making these decisions. Moving on, if you were away have no fear because you can still grab a form from Mrs. Bjornson and look at the google classroom for any details on what you missed. - Reminder to hand in course forms, and to bring your own calculator to class. Wednesday, February 21: Today, Mrs. Bjornson started the class with important life lessons about wanting to do our best and pressure to succeed; we shouldn't let ourselves go to harmful comparisons of ourselves, just be happy you're healthy and still full of life. Without further ado, let's get on to our new trig lesson on finding lengths using SOHCAHTOA!! So to start off (ever so matter of factually, I know) we have to label the sides of the triangle with it's hypotenuse, opposite side and adjacent. Afterwards, find the "unknown" and 2" knowns. " Then use the sine, cosine, and tangent functions to pick the correct trig function for your problem. Last but not least put it in two ratio/fraction forms and multiply the pair and divide the spare for the answer. Example: A triangle has an angle of 45° and a hypotenuse length of 6 cm and an unknown (x) opposite. What is the length of x? sin45° = x/6 sin45° X 6 = x 4.2 = x * Don't forget to circle your answers * HAPPY LEARNING CategoriesHey guys it’s Alex here doing your Monday fun-day blog!!! (even though this post came out Tuesday morning) In class we learned how to get angles using Tangent, 2.1 in the textbook and Sine/Cosine, 2.4 in the textbook. In the tutorial video the nice british man explains how to find angles using tangent, sine, and cosine ( more on that in a second). The nice friendly british man in the tutorial video DOES NOT PUT HIS FRACTIONS INTO DECIMALS!!!!! Like Ms B said we do not care about the decimal. For example if you are using tangent and your opp is 4 and you adj is 14 all you need to do is put X=tan-1 (4/14 simple just put a bracket between the tan-1 and the number and just divide. I hope that made sense, if not please watch the tutorial video To get your angle you will only need to know 2 lengths. If you have 2 lengths, you will need to label them. If you need to know how to label, go read the last blog post that Sarah did. It will help a lot!!:) once you have the lengths labeled you can will need to use SohCahToa or your brain to figure out which equation to use. When you have that down you can plug in your equation into the calculator. Do not forget to hit your 2nd, shift, or inverse button before hitting that sin,cos, or tan option. Last but not least. Do not commit a math sin. I missed a very funny joke thingy that happened and Ms B even explained it to me:’( and I still didn’t understand it. I have committed the real math sin. Hi everyone! It's Sarah with ya blog post. At last. Sorry for the delay, but I wasn't able to make a post on the actual day of the lesson. Got locked out, gosh darn technology! Anyways, we learned about trigonometric ratios. SOHCAHTOA and all that good stuff. But more on that in a sec. We also refreshed our collective memory on how to label a triangle. The long side opposite to the 90 degree angle is the hypotenuse (hyp), the side opposite and the side adjacent to 'x' are opposite (opp) and adjacent (adj) respectively. Just like the diagram above! Now, back to everyone's middle name (according to Schwab) SOHCAHTOA. If you forgot, SOHCAHTOA means Sine=Opp over Hyp, Cos= Adj over Hyp and Tan= Opp over Adj. And that's totally it for trig ratios! Note the comic sans. WHEN YOU CAN'T GET INTO THE BLOG AND POST IS LATE.
Hi everyone, it's Sheyda, and I'm back for yet another blog post :) So this blog post isn't about lesson per say, however, it is about some pretty important facts you should know. So for those of you who might have missed Friday's class (Feb. 9th), we had a collaborative quiz. The format of a collaborative quiz is straightforward. Everyone will receive their own individual quiz, but you are welcome to discuss with the people around you if you have any questions or concerns. Now, when I say discuss, I don't mean you can yell across the room. Even though this may be a collaborative quiz, you must keep the room environment quiet. We must respect each other's learning needs :) Now, if you're like me and you freak out when there is a quiz, DON'T! Why? Well, because it is always possible to get 100% on a quiz, even if you don't get all the correct answers. If you get all the questions right, bravo! If you don't here is the way to get full marks. Correct your quiz. Yeah, that's it! If you can correct your quiz showing the steps of how to get to the right answer, then you can get full marks. Also, just to let you guys know for those who were wondering, these quiz will make up ≈ 1% of your total mark. The first collaborative quiz on Unit 1 was corrected today in class. If you missed it, the answers as well as the quiz itself are now available on Google Classroom under the "Stream" section. Here is the link to GC : Now, we are going to change topics. We are going to talk about homework. So our first unit test is just around the corner (This Thursday, Feb. 15th fyi), and that means that it is almost time for us to hand-in our homework sets! Don't worry if you still aren't done, you still have 2 days left to finish it. And if you don't finish it come time of the test, you have 2 school days to hand it in, but try and get it done for the test day if you can. For each section of the unit homework you must give yourself a mark out of 3 :
There are more details on the Homework Process on Google Classroom : I hope this was helpful to anyone who had any questions or concerns. Have a great and happy Tuesday! P.S ~ Tomorrow is Valentine's Day <3 !
Sorry I missed last week. Wanna join my free gift card giveaway? Click the subscribe button, turn the notifications on and finally leave a nice comment down below.Spheres! And Hemispheres! Hey everyone, Campbell here. (Totally writing this while listening to my brother play Tainted Love 10 Hrs.) For the past 2 days we've covered SPHERES. (How to calculate surface area, volume, and fun facts about them.) A sphere is a thing that has all its points an equal distance from the center. We also covered circles (If you don't know what a circle ( cir-cle) is, go to Kindergarten). We also talked about hemispheres, which are HALF OF A SPHERE. On day #1 we started with a cool activity were we made a graph as a class showing how great our calculations are for finding PI. We were only of by a very small itty bitty tiny bit. BTW, check the graph now. It's 100% satisfaction guaranteed! We then tried the first question in the notes, where we had to find the diameter of a soccer ball. After we did that (or copied Ms.B) we talked about Archimedes (Greek guy) and the story of him trying to find the volume of a crown for a King. Ms.B told us about how bathing helps people think, which is how Archimedes thought of how to find the volume of the crown. He then proceeded to run down the street nude (The difference between naked and nude is that naked means feeling vulnerable, nude is being without clothes). So we then started the next problem in the notes, where there's a sphere dropped in water, and we need to know the water depth. We did half of it, then waited to today to finish it! When day #2 started, we finished the problem from yesterday. I'm not gonna tell you the answer, or how to solve it, since part of the problem is figuring it out for yourself. (Some of us learned the symbol for Therefore. That was nifty.) We then talked about the pyramids in a sphere(not real pyramids) that are all connected to the center. We discovered that the VOLUME of the pyramids are equal (=) to the VOLUME of the sphere (Cause they're kinda inside the sphere and take up all its space). And now the part that some of you (like me) are all waiting for if your just too lazy to check the sheet (like me)! HOMEWORK: pg. 51: #3b, 4b. 5b, 8, 13, 17, 20 and pg. 54: #5b. Time for some selfish advertising. I am totally making a movie, and starting a club for meetings. Just ignore the people trying to get you to go to their clubs, and listen for the announcement to come to Movie Club at some lunches. JOKES (are for losers. the best jokes are ones were they're not typed) RIDDLES= Ask me on Monday for the Answers If you're in a race and pass the runner (or walker, driver, etc.) in second place, what place are you in? EASY When does yesterday come after today? TRICKY A woman (or man) is sitting in their hotel room when there's a knock on their door. They open the door to see someone they have never seen before. The stranger said "Oh, I'm very sorry. I thought this was my room." The stranger then leaves. The woman (or man) immediately phones security. Why? FUNNY What has an ostrich butt, besides a ostrich? JOKE Hey everyone! I hope that you had a great and relaxing weekend, and that you had a good Monday. So, this post deals with unit 1.4 and stretches over both Monday and Tuesday due to the fact that we did not have enough time to finish the lesson on Monday. I'd like to thank Chloe for that amazing video that we watched on Monday. Seeing as this 'class' was over two days, I'm going to put everything that was non-math related (but still important, imo) at the top here and then I'll put the math-y stuff in the next paragraph. We got some good info on what is important to put on our scholarship resume and what isn't (anything before grade 10). Also, saying that you've done a math contest will look good, so if you want to sign up for that check out the google classroom. You can hand in a form that will let Ms B know if you want to do it this year. Volunteering also looks great, on any type of resume(i think), so if you see anything that needs doing in the community, at school, in the city, see if you can volunteer to help that, or start your own initiative. Ms. B's room is also always open at lunch to eat and/or to do homework, so if you have any questions she, or another student, will probably be able to be of help. A great idea was proposed for our class: we could go outside everyday before class, even for just five minutes. Personally, I think it would help to wake me up, and even if it didn't, I think it would just be fun to get some energy out before math.
So thats everything atually relevant for for today, now onto some out of context quotes:
"This seems like a lot of b*s" -Ms. B "'Cause math is stupid" -Katie I hope that this helped and that I didn't miss anything, if I did, please let me know in the comment section down below, I hope everyone has a great night! -Emma |
