Today in class, we didn't do that much work, we only have to finish one Assignment/Homework.
Here's our Assignment/Homework :

Hello everyone. I'll just be showing you 5 examples from our homework. And Simran will show you another 5 on her post. My 5 questions are on the first page/pg. C-41.

For homework we got assigned to do 37 questions from a work sheet. For my scribe I will be doing 5 questions from C-42.


For my next question I did the first word problem on C-42.





Always remember to put your simple word answer first! Now Here is how I got the answer:

Here is my 3rd question:


Here is my 4th question:

Now here is my last question for my scribe!



That was my scribe, I hope it helped you with your homework! For the next scribe I choose Kara.

The second way for subtracting mixed numbers is to borrow. You use this if the wholes are big, and when you don't want to multiply (if the number's too big for you). To use this, you write the mixed number a different way, but still having the same amount (eg. 36= 35 4/4). Add the whole with the fraction (35 4/4 + 1/4). Then, you could subtract. Which gives you the answer (33 2/4 or 33/ 1/2).

This is another question using way 2: borrowing.

Don't forget to do your homework (worksheet). And if you're not done your eportfolios, finish it . One more thing, the 2 minutes storyboard and script are also due on Monday.

For the next scribe I pick Kristin.

Today in class we went over our homework, the 4 adding fracion questions and the 3 word problems. Here are the correct answers:

Also we got word problems i will do 2 of them:

When Betty opens the cake box, Betty finds that 3/8 of the cake has been squished. Luckly she finds half a container of ice cream in the freezer. If she molds it properly she will have enough to make the cake whole again.

3/8 -cake

1/2 - ice cream

3/8 + 1/2 =

3/8 + 4/8=

= 7/8 !

next question

Betty is making punch for the party goers. She needs 3/5 L of orange juice, 1/2 L of lemonade and 1/4 L of Grenadine. How much liquid is in the punch?

3/5 -orange juice

1/2 - Lemonade

1/4 Grenadine

3/5 + 1/2+ 1/4 =

12/20 + 10/20+ 5/20=

= 27/20

change to mixed = 1 and 7/20

Thanks and please leave a comment. For the next scribe i choose Lina! For people who don't know who that is, it's Zerlina.

Today in class we still talk about squares but we also learned how to cut them into equal pieces. We used tiles to make them in eqaul pieces.

I am gonna make some examples of how to cut them into equal pieces.

I dont know how to explain it in words so I am just going to put some more pictures as examples.

all you do is basicly cutting them in equal pieces.

I hope that you have understood what i have done. Sorry for any mistakes I have made. PLEASE leave a comment.I choose ANYONE who wants to do the next scribe. 

Today in class we made a times table (12x12). We made this on grid paper and made a chart along with the times table called the Perfect Square Chart.

On the times table, we were suppose to color the numbers that would make a perfect square which would be in a diagonal. And color the other numbers with different colors, like so


And here is the Perfect Square Chart. In this chart it has the number squared, the factors, and the answer.


We also had to answer "to be in the Perfect Square club you must be..." and "if you don't belong to the perfect square club you..."

I answered these the best I could.
1.) To be in the Perfect Square club you must be a whole number meaning you cannot have a decimal.

I hope that you have understood what i have done. Sorry for any mistakes I have made. PLEASE leave a comment. I choose Andrew to do the next scribe.

So today we corrected right angle problems and the mean, median, and mode problem. Then, we were given 3 problems to solve using the Pythagoras theorem. TEST : THURSDAY. These problems will help you better on the test.

By the way, √ <-- this means the square root. Question 1:
a^2+b^2=c^2
a^2+2^2=8^2
-2^2 -2^2
a^2=8^2-2^2
a^2=64-4
a^2=60
√a^2=√60
a=7.745

Question 2:

a^2+b^2=c^2
a^2+13^2=20^2
-13^2 -13^2
a^2=20^2-13^2
a^2=400-169
a^2=331
√a^2=√331
a=18.193

Question 3:

a^2+b^2=c^2
6^2+b^2=23^2
-6^2 -6^2
b^2=23^2-6^2
b^2=529-36
b^2=493
√b^2=√493
b=22.206

After, we were given these questions:

I can't really help you on this because I don't understand the last 2 questions.

But the first questions answer is : 1/3

Thank you for reading! Tomorrow is my last day! Comment!

The Following times were recorded, in seconds. For the runners in a race.

The Pythagorean Theroem is something we have been learning in math class for about two weeks now.

Vocabulary
legs - the two sides of the right triangle that makes the 90 degree angle (side a and b)
hypotenuse - the longest side of the right triangle (side c)
R.A.T - Right Angle Triangle. Has a 90 degree angle
Greek - a person from Greece and the form of language
theorem - something to be proved from other formulas.

Artifacts

1st
Pythagoras
A Greek mathematician who was born between 580 and 572 BC, he died between 500 and 490 BC. People call him the "father of math and geometry." He was the first person to discover that the earth was round and that it revolved around the sun. He was also the first person to be a vegetarian (a person who only eats vegetables). Pythagoras is also famous for the Pythagorean Theorem.

2nd
Pythagorean Theorem

3rd

Right Angle Triangle (R.A.T)

• 90 degree angle
• Theta and Beta
• hypotenuse (side c)
• legs (side a and b, makes the right angle)
• half of a rectangle or square

4th
Square

• 4 - 90 degree angles
• total - 360 degrees
• quadrilateral
  

Questions
We had all sorts of questions concerning the Pythagorean theorem, trying to figure out what a, b, or c was. We also had word problems involving this theorem.
