Midterm Self Assessment and Goal-Setting
It seems like just yesterday, starting science 10 but now we have reached the middle point.
So far we have completed our biology unit and are almost done our chemistry unit.
In biology unit I think I understood concepts very well, with little reexplanation required. I was able to complete all of the assigned work and I understood all of it. I struggled with thinking down to such a small level. Trying to figure out how everything worked autonomously keeping us alive was fascinating to me but still it was slightly confusing trying to understand how something could function so perfectly yet not be conscious.
In chemistry I have been doing very well with balancing equations. I have been enjoying balancing as it always works out in the end. Its like a puzzle with the answer appearing if you think hard enough. something I struggled with was the chemical formulas, I found it confusing at first but the more I practiced the easier it got.

Residential School Word Cloud
This word cloud is a reference to the story “Sugar Falls” by David alexander Robertson and Scott B. Henderson. The cloud references residential schools and missing and murdered indigenous women including Helen Betty Osborne.
“Week 17” In math 10
Week 17
Time flies doesn’t it?
It seems like just yesterday when I started these blog posts and with a snap we are at the last.
As this will be my last blog post I thought I would do something different, in light of the upcoming final.
In todays blog post I will be going over all of the blog posts I made.
We will be going from latest to newest.
“Week 16” In math 10
In this week we went over all of the systems of solving equations.
Reminder:
Systems are
- graphing.
- substitution method.
- elimination method.
Week 30 ➗ 2 In math 10
This blog post was about an assignment handed out to me from my teacher, the assignment required me to have to graph my initials.
Reminder: Rise over run
“week 14” in math 10
This was not my greatest post, but it has useful information nevertheless.
In this blog post I went over how to find the slope of an equation without graphing.
Reminder:
Week 13 in math 10
In this blog post I went over how to find rise over run using a graph.
Reminder:
Rise=Y
Run=X
“Week 12” In math 10
In this blog post I went over how to find the domain and range of an equation
Reminder:
Range = bottom Y coordinate and top Y coordinate.
Domain = Left X coordinate and Right coordinate X
“Week 11” in Math 10
In this blog post I go over how to find the Y and X intercepts of a rule.
Reminder: Isolate Y
“Week 10” in math 10
In this Blog post I go over how to Prepare for a test.
Reminder: SLEEP!
“Week 9” in math 10
In this blog post I teach how to find out what sides are: opposite, adjacent and the hypotenuse on a right angle triangle and also some tips and tricks to remember!
Reminder:
Opposite side is furthest from the hypotenuse point
“week 8” In math 10
In this post I show how to factor polynomials.
Reminder: The second numbers sum is two numbers times together equaling the last number. (read the post)
“Week 7” In Math 10
In this blog post we go over how to multiply polynomials, using a formula called “the window method.”
Reminder: Keep track of all the numbers.
“Week 6” In Math 10
In this post we traveled back to grade nine to remember how to solve a simple polynomials equation.
Reminder. x² and x are different, don’t add them!
“Week 5” In Math 10
In this week I went over how to calculate an angle on a right triangle.
Reminder: To solve for an Angle you have to use Sine, Cosine or Tangent to the power of -1.
Week 4 in Math 10
This is one of my best posts, in this one I show you how to use a calculator to calculate Sine, Cosine and Tangent (or Sin, Cos and Tan for short)
Reminder: The “2nd” button is very important.
“Week 3” in math 10
In this post I go over how to use scientific notation.
Reminder: don’t count the first digit.
“Week 2” in math
In this post I go over a simple way to find the factors of an equation.
Reminder: KEEP TRACK OF THE NUMBERS (I speak from experience)
“Week 1” in Math 10
And we have reached the bottom, 16 blog posts later.
In this blog I talk about how I use math in my day-to-day life.
Reminder: math can be useful (sometimes)
And that’s all.
looking back, I might miss this…
Have a good one!

“Week 16” In math 10
As you might know, week 16 of math 10 was the week before Christmas break and as you could guess students (me included) were dying to escape the confines of our classrooms. But nevertheless blog posts don’t stop for no break.
In this blog post, I am going to go over different ways to solve a system.
our ways being:
- graphing.
- substitution method.
- elimination method.
To start off lets get our equations
Sweet, right off the bat lets go over how to solve with graphing.
Lets load up our trusty graphing calculator
To solve this equation we need to place both of our equations into desmos.
Like so:
Now you want to look for the middle coordinate. The middle coordinate of this equation is (-1.333,1) not a great point but one nevertheless.
you can do this but i would recommend the other options as this takes a large amount of time.
On to the next!
The substitution method!
to start off the substitution method you need to choose one of the equations and isolate it.
Unless your equation is is already set up like ours is.
all we have to is place the Y intercept form of the equation in the part where the Y is on our second equation.
like so:
now we need to times to two into the equation.
making it
Now you just need to isolate the variables
leaving us with:
finally you need to divide 12 by -9 leaving us with X= -1.333
to find Y all you need to do is go back to the original equation and replace X with the number.
The elimination method!
The elimination method is my preferred way to solve systems
The elimination method requires you to eliminate one of the variables through either adding or subtracting.
To do this you would take your two equations and either subtract or add them to remove a variable.
if we add
with
we are left with:
3 = 3y
and dividing that we get 1
place that back into the equation replacing Y you get the next digit of the coordinates.
I hope you better understand how to solve a system using these methods. If you don’t, feel free to comment your question and I will try my best to answer it!
