Math and Grammar Reviews

Hello class. I'm sorry I was sick today. We can talk about everything if I'm at school tomorrow (which I should be, I'm trying to get better!), but if you had problems please let me know. Also, did you get to review grammar with Luisa? What about types of writing? Please let me know.

Okay, tomorrow you have your grammar final and your math final. We'll go over math and grammar tomorrow at school, okay? I'll go over the answers of your homework and I'll help answer your questions. I know Warren helped you a little, but I want to make sure you understand everything.

For your math final, this post will tell you about the math final: http://hoyengradoquinto.blogspot.com/2010/11/math-review.html

There are 70 questions over most of the things we learned this year. You do NOT have to estimate or know place value. You DO have to write in word form, add, subtract, multiply, divide, use fractions, use decimals, compare numbers, and use algebra skills. You also need to know everything we did in Term 4.

Below, I've listed problems and I've posted your quiz and your math test from this term...
Here is your first math test over number theory: https://docs.google.com/fileview?id=0B3Gs8USRVEoYZDI2M2UwZjItZjQ1ZC00ZDAzLTgxNTgtZTY2OGVlMWM0NGZi&hl=en&authkey=COiZpf4M

Then, to review geometry, you should study the quiz you took last week. You can find it here: https://docs.google.com/fileview?id=0B3Gs8USRVEoYZjMyMWQxYmYtMDZlOC00YzY4LWIxZTMtMGNlMDU0OWM0ZGM5&hl=en&authkey=CNCb-MwF
Just copy that link into the address bar and it should it work. If it doesn't, please tell me.

If you want to review more, try SOME (not all... seriously) of these problems:
To review for Term 4, I would like you to do all the ODD numbers on pages 300-301
Set A 1-13
Set B 1-15
Set C 1-13
Set D 1-17
Set E 1-15

You should also study:
All the problems on page 509
the types of lines on page 482
the types of angles on page 483
the problems on page 485
problems 4 to 15 on page 537
problems 12 and 13 on page 644
pages 674 and 675, you should do: Set B, 1-4, Set D: 1-6, Set E: 1-3, and all of Set F.

For your grammar final you should do this worksheet:
https://docs.google.com./fileview?id=0B3Gs8USRVEoYOTVjOWU0MGQtZDZjYy00NjE4LWJlZGEtYThiMjM5YTE4YjU5&hl=en&authkey=CLnB-bUK It's the same as this post: http://hoyengradoquinto.blogspot.com/2010/11/grammar-review.html

I'll post the answers at 6:30 p.m.

Math Review Answers

Page 208:
1. B, because 8.9 = 8.90 (zeros at the end don't change the value), but 3.11 > 3.011 (because zeros before numbers that are after the decimal point DO change the value)
2. C, because 8.11 is bigger than 8.10, 8.01, or 8.00.
3. C, because if you look at the number 38.452 and you want to round to the nearest tenth, the 4 is in the tenth place. So you look behind the 4, at the five. Five is equal to 5, so you round 4 to 5. So the answer is 38.5
4. D, You need to add $3.25 and $0.95 because that is how much money he spent. When you add them together, you get $4.20.
5. A, You need to subtract 2.7 miles from 3.2. Carlotta has to walk 3.2 miles total, and she's already hiked 2.7 miles. To find out how many she has left, you have to subtract.
6. C. Remember to multiply without decimal points and add the decimal point at the end.
7. B, because you round 5.24 to 5 and 0.82 to 1. That means you multiply 5 x 1, which is 5. The closest answer possible is 4, so the answer is B.
8. C. If Neil can type 50 words in ONE minute, and you want to know how many he can type in 7.5 minutes, you need to multiply 50 x 7.5. That gives you 375!
9. A. Don't forget, when you divide decimals, you can add zeros onto the end of the dividend.
10. A, If Alyssa bought 4 pounds of oranges and saved $2.08 total, to find out how much she saved per pound you need to divide. You divide $2.08 by 4, and the answer is $0.52.
11. 0.493 rounded to the nearest tenth is 0.5, rounded to the nearest hundredth it is 0.49
12. The answers are A=0.5, B=1.3, C=2.4, and D=3.6
13. If one wedge of cheese costs $3.95, and the wheel has 8 pieces of cheese, the whole wheel of cheese costs 8 x $3.95, which is about $32. You can round 3.95 to 4, and multiply 4 x 8, which is 32.
14. Andrew's fish weighed more because Simon's two fish together weighed 5.18 kg, but Andrew's two fish together weighed 5.43 kg. You need to add each person's fish to find out how much they weigh together.
15. If you round all the numbers in the chart, most numbers are closer to 20, not 25. That means that $20/hour is a better estimate.

Page 334-335
1. There are 5 stars. 3 of them are colored. That means the fraction is 3/5.
5. The rectangle is divided into twelve parts. 8 parts are green. The original fraction is 8/12. We can divide 8/12 by 4 and get 2/3. 2/3 is the simplest form.
6. Line C, because 2 1/4 is more than 2, and 1/4 is halfway between the whole number and 1/2.
7. B, 1/2. That is because 0.5 is 5/10. We can divide 5/10 by 5, and it becomes 1/2.
8. B, because 1 1/3 is more than one, but not a LOT more than one.
9. In order from least to greatest: 1/4, 3/8, 1/2.
13. 1.4, 2 1/5, 3.7
15. 2/4 = 0.5, 5/10 = 0.5, 7/10 = 0.7, 3/4 = 0.75, 3/5 = 0.6

Math Final

Hey class!! Earlier Antonia asked if this was all you need to study... so, I'm going to tell you exactly what is on your math exam right now!

1. You need to write decimal numbers in word form. (example: 324.42 is three hundred twenty four AND forty-two hundredths)

2. You need to know the value of a digit in a decimal number. For example, in 3.456, the 4 is worth 4 tenths, the 5 is worth 5 hundredths, and the 6 is worth 6 thousandths.

3. You need to compare decimal numbers using <,>, or =. For example, 3.5 = 3.50, but 3.5 > 3.05, and 3.5 < 2 =" 6." style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 500px; height: 500px;" src="http://upload.wikimedia.org/wikipedia/commons/thumb/4/4f/PieChartFraction_threeFourths_oneFourth-colored_differently.svg/500px-PieChartFraction_threeFourths_oneFourth-colored_differently.svg.png" border="0" alt="">

10. You need to be able to write a fraction in the simplest form. Here's an example:


11. You should understand the difference between irregular fractions and mixed numbers.

This picture shows a mixed fraction, 2 1/3:


12. You need to be able to make irregular fractions into mixed numbers and mixed numbers into irregular fractions. To make an irregular fraction a mixed number, you divide the top number (the numerator) by the bottom number (the denominator). So, 10/5 would be 10 divided by 5, which equals 2. 12/11 would be 12 divided by 11, which equals 1 with a remainder of 1, so the answer would be 1 1/11.

To make a mixed number an irregular fraction, you multiply the bottom number times the whole number and add the top number. So, 1 2/3 is 3x1 +2, which equals 5/3.

13. You need to be able to compare fractions using <, >, and =. So, which is bigger 1/2 or 2/3? You need to find a common denominator (use six for this problem). Multiply 1/2 by 3 and 2/3 by 2. You get 3/6 and 4/6. That means 2/3 > 1/2.

14. You need to be able to change decimal numbers into fractions. For example, 0.25 is 25/100, and that can be simplified to 5/20, which can be simplified to 1/4. (Or you can divide 25/100 by 25 and get 1/4!)

I'm posting the answers to the review in just a minute!

Math Final Tomorrow!!

Hey class...

Here are the problems you should do. I'll post the answers around 6:30 or 7:00, okay? If you have a question, leave a comment or send me an email. REMEMBER to check the comments or your email later, because I ALWAYS respond!
