Tech Team Year-End Evaluation

What did we do in Tech Team this year? What did I accomplish as someone part of the Tech Team?

I volunteered. A lot, I’d like to think. We had a number of events that required us, and I was present at many of them. I assisted the grade nines at the start of the year with setting up their devices. I led presenters around the school, and helped with setting up and taking down most exhibits during the CUEBC event. We hosted an event to show the kind of devices the school used, and I helped many parents decide what sort of device fit their child’s needs the best. I believe I certainly helped during these events, but for next year, I wish to be a more prominent sort of presence during the next year.

Technology for Parents, to Help Parent

Parenting is tough, that’s a given. Throwing technology into the mix of raising a child is terrifying. Just thinking of all the risks. But it can be made safe. There are tons of ways to keep your child safe whenever he/she is using a computer. Plenty of programs can help monitor activities that happen on the computer, acting as a sort of digital supervisor whenever the computer is in use. You can block or allow certain websites or programs to keep your child safe when surfing the web. Creating an administrator account on your device, and then creating a sub-account under that admin account lets you control any changes that your child makes when they’re signed into the sub account.

Probably the most important thing to do before letting them use a computer is explain the dangers of the internet and technology. It’s imperative to let your child know that the internet can be a wonderful place, but when used inappropriately, it can be dangerous. Things like malware, adware, and other phishing scams can damage not just your device, but your life. Losing money to someone who claims to be a Nigerian prince who is your long lost cousin, and needs money for an “investment” is not uncommon. However, teach your kid how to be safe online, and everyone will have a wonderful time.

Math 10 Week #17

This week,  we covered systems of linear equations. Systems give us two lines, and we are supposed to find the point at which these two lines intersect. We learned about three different methods to solve systems. One of these ways was to simply graph the two lines given and see where they intersect.

Another solution is to substitute one equation for another. Say you have two equations:

  1. 3x+2y=4
  2. x-3y=5

x is currently by itself. Simply isolate x, and the equation is now x=3y+5

Substitute x into the first equation, and you now have 3(3y+5)+2y=4. Expanded, it is 11y=-11. We now know y=-1

Substitute y=-1 into one of the equations, x-3(-1)=4

x+3=4. This means x=1

The lines intersect at (1,-1)

Math 10 Week #16

This week we discussed how to write different equations representing lines on a graph. There are three kinds of equations: slope-intercept form, general form, and point-slope :  form.

Slope intercept form: y=mx+b, where m represents the slope, and b is the y-intercept.

General form: Ax+By+C=0, where A>0, and A,B, and C are integers

Point-slope form: m(x-x1)=y-y1

Slope intercept form is the form that is used most of the time. Sometimes General form is used for an equation to look “nice”, because everything is on one side of the equation. If you have an equation in slope intercept form, that equation can be converted into general form.

y=\frac {2}{5}x-1          Converted into general form, the equation will say

2x-5y-5=0
