Today you should send me only #8 and #14 from 7.1 Co-ordinates of Points on a Grid.
New work to move on to is 7.2 Translation. Complete questions #6 to 13 in the text. Answers will be posted on Tuesday.
Some background info on Transformations.
- Transformations are movements of points or figures on a grid.
- a Translation is a movement that combines a shift of the coordinates both left and right, and up and down without changing the orientation of the figure - these are also called slides!
- the movement is defined by a vector - for example [5,2] - notice the square brackets - the means its a vector and not a coordinate - coordinates use round brackets (5,2). The vector [5, 2] means 5 spaces to the right and 2 up. A negative is used in a vector to show a movement down on the y axis and left on the x axis - for example [-5, -2].
- when you slide a figure, the new figure that you draw is called the image. Label the coordinates of the image with capital letters but with a superscript I as you see in the text book example of the boat figure in the lesson.
- a translation can also be shown with a vector arrow - the vector arrow shows the exact movement and direction as seen in the text.

Thank you for sending your Test Yourself scores out of 30 for Chapter 10.
Now we will move on to our last Chapter of new work for Grade 8 - Chapter 7 Transformations. To begin we'll do some Math Art as described on page 220 called Getting Started.
To help, I've created step by step instructions. The first is the simple one called Tesselations 1. If you want more of a challenge, check out Rotational Translations!! Please send me a picture of your creations!
In either case you need to start with a square of paper. You'll need scissors to change the shape and some tape to tape it back together. Then you trace your tile over and create a pattern.

Steps to Solve Pythagorean Theorem
Method #1 when the hypotenuse is unknown
a² + b² = c² write out the formula
3² + 5² = c² substitute the numbers you know
9 + 25 = c² square those numbers
34 = c² add them
√34 = c
√34 = 5.83 find the square root
c = 5.83 the square root is the length of the unknown line of the triangle
Method #2 when one leg is unknown
a² + b² = c² write out the formula
3² + b² = 5² substitute the numbers you know
9 + b² = 25 square those numbers
9 – 9 + b² = 25 – 9 isolate the variable
b² = 25 – 9 subtract
b² = 16
b = √16 find the square root
b = 4 the square root is the length of the missing leg of the triangle

These are the ANSWERS for 10.5 Exploring Right Angles. Check it out to see how you did.
B. The angle measures are 90°, 20°, and 70°. The two smallest angles are complementary because they add up to 90 degrees.
D. The area of the square on the baseline is 27 m × 27 m = 729 m2. The area of the square on the foul line is 10 m × 10 m = 100 m2.
F. The length of the hypotenuse is about 14.4 cm, which is 28.8 m. Therefore, the area of the square on the hypotenuse is 28.8 m × 28.8 m = 829.4 m2.
G. The sum of the areas of the two smaller squares (729 m2 + 100 m2 = 829 m2) is approximately equal to the area of the larger square (829.4 m2).
H. The distance thrown is the square root of the sum of the areas of the two smaller squares. Using a calculator, 829 = 28.792 36, so the length of the hypotenuse is about 28.8 m.
Question #1. Why are the two non-right angles in a right triangle always complementary?
Answer #1. A right triangle always has one 90° angle. Since the sum of the angles in a triangle is always 180°, then the sum of the other two angles must equal 180° − 90° = 90°
Question #2. What did you learn when you compared the areas of the squares on the three sides of the right triangle?
Answer #2. The sum of the areas of the squares on the shortest two sides of the triangle is equal to the area of the square on the longest side of the triangle.
Question #3. How does the length of the hypotenuse relate to the lengths of the other two sides of a right triangle?
Answer #3 The hypotenuse is the square root of the sum of the lengths of the other two sides that have been squared.

How did the Exploring Quadrilaterals go?? Check out the video below which shows the process and helps explain it.
New for today is 10.5 Exploring Right Angles. Try following the instructions A to H and answer the reflection questions 1 to 3. I'll provide the solution tomorrow. You will need 0.5cm dot paper which I have provided below. If you can't print it for some reason, then your grid paper in your notebook will work as well but your drawing will be much larger.

The world changed and the math text book didn't!!!
I took a closer look at question 4 from 12.4 and I realized that this question was published when we still used pennies!!! If you don't consider using pennies, then it doesn't really require an organized list at all. 25 cents can be made up with only a few combinations of quarters nickles and dimes - in fact just 4 combinations! No need to submit!
Today you will move on to 12.6 Designing a Probability Model. As with all Exploration lessons, follow the instructions A to E and answer the reflection questions #1 to 3. Note that step D asks you to compare with your classmates - please try to do so with one other person if possible. No need to submit.

12.1 Understanding the difference between Theoretical and Experimental Probability.
When guessing one card from a total of 4 possibilities, then your chances (probability) of guessing the right one is one in four or expressed as a fraction one over four. This is called the theoretical probability. It is only theoretical because as you learned, that it is possible to guess ten times in a row and never get the correct answer. BUT, as you should have discovered by creating a chart with the percentages and then a graph of those percentages, is that the more you repeat the 'experiment' (guessing which card), the closer your percentage gets to one out of 4 which is 25%. So, what happens is, if you were to repeat the experiment 100 or even 1000 times your percentage would eventually settle out at 25%. mr. naccs
When guessing one card from a total of 4 possibilities, then your chances (probability) of guessing the right one is one in four or expressed as a fraction one over four. This is called the theoretical probability. It is only theoretical because as you learned, that it is possible to guess ten times in a row and never get the correct answer. BUT, as you should have discovered by creating a chart with the percentages and then a graph of those percentages, is that the more you repeat the 'experiment' (guessing which card), the closer your percentage gets to one out of 4 which is 25%.

Please submit homework from 9.4 Fractions of Fractions (text book #7 to 11)
Today move on to 9.5 Multiplying Fractions.
Here are some tips for this lesson.
1. Recall that when multiplying fractions, you multiply the numerators and the denominators separately.
2. Recall that any whole number, when represented as a fraction is improper. For example, the whole number 4 as a fraction is 4 over 1. So when you have a whole number in a multiplication question, change it to improper first.
3. The textbook uses fraction strips to try to model multiplying fractions. this is a difficult concept. You may better understand the model that uses grids. I have copied a Virtual Blackboard lesson below to help. We will use only the grid models.
Your practice work will be to complete the exercises in 9.5 of your workbook and submit them for evaluation by Monday April 13.

https://courseware.cemc.uwaterloo.ca/27/assignments/560/0
This video from the University of Waterloo courseware (above) does a good job of explaining how to multiply fractions and how to show a fraction of a fraction. Remember in Math the word 'of' means multiply! Modelling fractions with strips is quite a challenge to teach you digitally. Here are some tips:
1. Think of a fraction strip as a number line that is very fat. So a whole fraction strip represents the number 1. If it is broken up into 5 equal parts than each part is one fifth.
2. Really study the yellow boxes that explain the lesson in the text.
3. Notice how the fraction strips are lined up and they are the same size - b/c they represent 1 whole. So you can see that one half of one third - is one sixth. This proves what you already know about multiplying fractions - you multiply the top numbers (numerators and you multiply the bottom numbers (denominators) separately.
Please send questions if you need to during the work day.
Complete text questions 7, 8, 9, 10 and 11. The answers are not in the back so submit to me on Thursday April 9 for assessment
