Nov 24 classwork

Homework for 17th

Finish worksheets handed out in class (algebraic expressions exponents...), practice probability quiz.

Definitions on probability terms.

Homework due November 3

1. Spectrum pages 75-78: Read and do the problems. Be prepared for some graded classwork on the concepts that are covered on these pages. I will be scanning in some additional material on probability for those of you who are interested and are worried about SSAT questions.

2. Be able to define all of the bold-faced words used in pages 75-78.

3. The 3 page classwork packets were handed back to all of you with a cover sheet that needs to be completed (both sides.)

Correct any parts of the worksheets where you received less than full points. I will do a second grading of the corrected answers. Your second grading CANNOT BE LESS than the first, as I will NOT be taking away points!!! Then, I will average the two grades!

4. I did not collect pages 41 and 42 from the Spectrum book (customary measurement exercises) so you will have these pages to review for a possible quiz next time on ounces, pounds, inches, feet, quarts, gallons, pints, etc. Make sure pp. 41 and 42 are ready to be handed in on Nov. 3, too.

5. Have a good break!

Homework, Week Four (due next class)

It only looks like a lot:

pages 41-42 review of customary measurement
pages 88-91 review of geometry with special emphasis on similar triangles. I gave a class handout that I said I would be collecting on Thursday. I will collect it on Monday, at our regular class. Show all work and be prepared to do a short quiz on similar figures, i.e. similar rectangles, etc., using proportions.

Quiz Results: Pretty Good So Far!

To the three eighth-graders absent yesterday (9/29) I will hand out a replacement quiz for you to do at home and turn in next week. It shouldn't take you longer than 45 min. and you may consult your text if you need to.

Homework, Week Three

In class this week we reviewed percentages and how to find them. Your assignment is to complete all of 3.1 (we started in class) and the 3 pages of section 3.2. I had recommended doing column a only, but do check your answers and make sure you can do this. The answer key should help you out. If you are taking a while to get the hang of it, please do all. There will be a quiz on Monday on percents, ratios, and proportions.

I reviewed how to do percents as a proportion in class and I wish the book showed that technique for each of the 3 different kinds of problems you see in section 3.2.

For example, if you have to find 8% of 25 you can simply multiply .08 times 25 or

set up a proportion 8/100 = n/25.

Either way will get you the same answer. Try using the proportion method some of the time to be sure you feel comfortable with it.

Possible Pop Quiz on the Horizon

Just a warning to eighth-graders: this is the best way to be sure you are using your homework time wisely. You have a key in the back of your book to check that you know what you are doing. You have many examples in the texts and handouts. Be prepared to show what you know about ratios and proportions.

Vocabulary Words

Improper Fraction
Mixed Numeral
Reciprocal
Fraction in Simplest Form
Ratio
Proportion
Factor
Multiple
GCF (Greatest Common Factor)
LCM (Least Common Multiple)




I urge you to use your own words, giving examples to help you to remember these concepts. The more you use your own words, the surer you will be of being able to remember these! At least that's the theory! And, when we have a test, you'll be able to use your vocabulary sheets.

Handouts and Homework, Week Two

Here are the four pages I handed out in class.
They are due next class, 9/22. For the percent page, please memorize where indicated!! Plus, please look over pp. 23-24 in your book and be able to do problems like the word problems on p. 24. You might want to practice as I suspect that there will be a quick quiz on using proportions to solve word problems.
Use pencil and show your work.

For those of you really into math, take a look at this site and let me know if you are interested in forming a group/team. It would be fun to compete!!

Homework, Week One

1.6: 1e,2e,3e,4e,5e
1.7: row 1
1.8: rows 1 and 2
1.9 rows 1 and 3
1.10: row 1
1.11 row 1
1.12: row 1
p. 16: probs. 6-8
2.1: rows 1-3
2.2 rows 1-3
2.3 probs 1-3

For 2.1 above, you are asked to cross-multiply to check if a proportion is true. Please do that for the exercise this time. However, I'd like you to think about the other ways we have of knowing when a proportion is true. For example, we know that a proportion such as 1/2 = 2/4 is true, even without cross-multiplying. Be ready to talk about the problems for 2.1 in which you really need to cross-multiply to check the proportion, and which ones you could test in other ways.

Writing assignment:

Define the following in your OWN WORDS and give examples:

improper fraction
mixed numeral
reciprocal
fraction in simplest form
ratio
proportion
factor
multiple
GCF (Greatest Common Factor)
LCM (Least Common Multiple)

Materials and books

Materials you will need for our class will be a thin three-ring binder with dividers for 3 sections: Worksheets, Vocabulary, and Quizzes. The Spectrum workbooks are yours to keep and you can write in them. Please only use pencil and show all work on your assignments. There is an answer key in the back of the workbook and it is a good idea to check your own answers to be sure you understand the material. Do corrections in a red pencil, so you will know what you have to study/review carefully. We will have weekly quizzes.

This site will be used to post all assignments and handouts, in case you are absent or lose one. If it seems helpful to everyone, I might add extra explanations after class on things we have discussed. Sometimes I will post puzzles that seem like fun.

If you have questions that can't wait for our next class, you can email me at kbalkoski@lelycee.org!
