Sometimes people miss a lesson in class due to illness or sports and start falling behind. One way to prevent falling behind is to watch, and learn from, the amazing collection of videos offered free online by KHAN ACADEMY.

I have viewed many of these video lessons and found them to be accurate.

So why bother learning this?

Well, in short, it helps your mark; it helps your understanding of the world; it helps support your brain knowledge; and once you have learned it you may find it is not difficult at all.

People wanting to go to university to be doctors, lawyers, engineers, or scientists all need to know this material. So, set aside some time, watch, and learn!

Get the point?

Enjoy,

Linear Relations Resources by UOIT

Education Teachers in Training at the University of Ontario Institute of Technology located in Oshawa Ontario Canada has posted some helpful math training videos on the topic of linear relations.

URL: http://faculty.uoit.ca/kay/G10_AppWebPage/linrel.html

I have viewed some of them and believe they can help students. Watch-Pause-Rewind and Watch Again!

So, if YOU want to learn about linear relations, slope, intercepts, and equations of lines, this could be a good place to start!

Which is your favourite video on the topic of linear relations?

Whole numbers, integers, and number lines!

Number lines help us organize numbers in size from small to big. The website http://www.mathsisfun.com/whole-numbers.html provides an interactive opportunity.

This interactive website is good for students that want to learn where to put points on a number line. Try it, you'll like it!

What are integers?

Integers are a type of number. The set of integers includes all natural numbers such as +1, +2, +3, and so on. And integers include all negative natural numbers such as -1, -2, -3, -4, ......and so on. Plus integers include the number zero.

So an integer is any number contained in the set of numbers {...-3, -2, 1, 0, 1, 2, 3, ... }

Is +100 an integer? Yes.
Is - 234 an integer? Yes.
Is  1.25 an integer? No, since the number 1.25 is not one of the numbers in the set of integers.

6 Tips for Grade 9 & 10 Math Students (Ontario)

Hanna's Math Tips For Grade 9/10 Students.

1st. Register for Free Math Online Chat Help for grade 9 and 10 students. approx 5:30-9pm Mon-Thurs.
Register using your Ontario Education Number (OEN) shown on any report card.
Register at https://homeworkhelp.ilc.org/secure/login.php

2. Find and bookmark http://www.khanacademy.org/math/algebra/quadtratics It has complete video lessons. Grab your questions, some pencils and paper, a calculator, and headphones. Give yourself 30-60 minutes to learn. Then watch, rewind, pause, and watch again. All high school math topics are covered here. Wow!

3. Make a Math "Vocabulary" List for new words, expressions, and formulas. Eg. What does FACTOR mean? What are the ZEROES of a quadratic equation?

4. Explore www.algebrahelp.com shows algebra tips and strategies for SOLVING EQUATIONS.

5. Write down any questions you have at night. Give the list to your teacher at the beginning of next class. Respectfully, ask to be shown how these (or similar) questions are done properly. Keep it to 1 or 2 key questions.

6. To boost confidence, follow this plan:

• Day 1 - Ask to sit in the front row to see better.
• Also on Day 1, ask at least 1 question during class;
• Ask at least 1 questions again for Days 2, 3, 4, and 5. Realize that nothing bad happens by asking a question.
• Then, from Day 6 and every day thereafter keep asking at least 1 question during class. It can be any question at all! This confidence building activity only works if the plan is followed. (Try writing down the questions the night before it that helps). Use a checklist to track your effort and results.

Finally, I am convinced that all students can learn math. But it takes time and effort.
Good luck. And never give up!
