OBJECTIVE: Find the (greatest) common factor of two or more
integers(6-4, 221ff)[1.1.3] ACTIVITIES: Review factors,
factor trees, prime numbers and prime factorization. Be sure
to place the emphasis on common factors not GREATEST) as the

OBJECTIVE: Identify and simplify rational numbers (6-5,
Pp224ff) and Express rational numbers as decimals and
terminating decimals as fractions. [1.1.3] ACTIVITIES: Take
time to introduce 'rational' numbers and compare them to
'fractions' including decimal fractions. Review decimal
division AND writing the problem when calculators are used.
NOTES: HOMEWORK: SHOW why fractions and decimals are rational
numbers

AW8-15 Joey dumped the change out of his pocket and found that he had 25 coins totalling exactly $1.00. What coins might Joey have had in his pocket?
AW8-49 When she was visiting her grandpa's farm, Trisha saw that he raised only hens and hogs. She counted 38 heads and 100 feet in the barnyard. How many hens and how many hogs did her grandpa have int he barnyard?
AW8-50 [Granola Bars $.10 Honey Drops 2 for $.15 Carob Chews 3 for $.25] Tom spent $1.00 on ggodies at the 'Natural Nibbles' store. He bought 11 items. What could he have bought?
AW8-74 Sandy is organizing a basketball league. She needs to know how many games will be played so she can reserve the gym. If there are 8 teams and each team plays each of the other teams twice, how many games will be played?
AW8-90 Allen and his friends are sitting at a large round table playing a card game. In this game, there are 25 cards in the deck. The cards are passed around the table, and each player takes 1 until there are no cards left. Allen takes the first card and also ends up with the last card. He may have more than the first and last cards. How many people could be playing cards?
AW8-105 ABC Company has just received 16 computers that must be divided among its 3 branches--Branch A, Branch B and Branch C. In how many ways can the 16 computers be divided among the 3 branches if each branch is to receive at least 1 computer?

And use it to find out what kind of fraction denominator various numbers make. For example, 3, as a denominator makes a repeating decimal. 7 does too, but it is more than one number before the pattern repeats. The program asks you how many places after the decimal point you wish to solve to. These are the screen prompts:
Solve 1/n to how many places? [the numerator is 1 because, if it is a repeating decimal, the answer will be a multiple of the 1/n answer.]
Enter your denominator:
At this point, the program will give you the prime factors of the denominator, then it will solve the problem to however many places you desire.
You have two choices:
- 1. Make a list of denominators which generate repeating decimals which repeat 1 numeral, then 2 numerals, then 3 numerals, etc. until you have a list of 10 denominators, the last of which contains a series of ten digits before it repeats. Be sure to explain how you chose your numbers.
or
- 2. Find a denominator which does not appear to repeat in the first 100 places.. Be sure to explain how you chose your numbers.
This is due no later than end of class on 29 January and is worth from 3 to 5 extra credits. Work from now until January 29 must be kept current.
