38, One day while I was at school, the electricity went out at home. When Ileft for school that morning, all the clocks were working and agreed that thetime was 6:30. When I got home they all showed different times. The wind-up clock, which was unaffected by the outage, read 5:21. The analog electricclock stops running when you unplug it from the wall and it starts up whereit left off when you plug it back in. That clock showed 3:50. My digital elec-tric clock, which resets itself to midnight electricity goes out and starts whenthe electricity comes back on, flashes until you correct the time. It was flash-ing 6:03 am. Assuming the electricity went out just once, what time did it goout and how long was it off?

Decimal multiplication Two Ways
Carlos:“Across the top I thought that one- tenth of 20 would be 2 so two-tenths of 20 is 4.Down the right side, 6 times 4 equals 24. Across the middle, I would have to mul-tiply six-tenths by ten to get 6. Two-tenths of 10 is 2. Down the left side, one-tenth of 20 would be 2, so six-tenths of 20 would be 12. 12 x 2 = 24 so it checks.”

Pat“Across the top, what could I take one-tenth of and get 8? It would have to be 80.Down the left, 2 x .1 = .2. At first, I did not know what to do with .2 x __ = 6.4.Then I thought that five two-tenths is one and thus 30 x .2 = 6. Just two moretwo-tenths gives 6.4, so .2 x 32 = 6.4. Down the right side, I figured 8 x 8 = 64 so8 x .8 would = 6.4. Across the middle 2 x 4 = 8, so it would have to be .4. Nowto check, is .4 x 80 = 32? Well, one-tenth of 80 is 8 and I need four of them. Inow see that four-tenths of 80 = 32.”

!!!!!!Benchmark PercentsMark is a manager of The Athlete Shop and is in charge of pricing sale items. In his jobhe often needs to mentally compute percentages of a specific dollar amount Here's anexample of how Mark does his calculations using "benchmarks":
A jacket is currently priced at $80.00. Mark already knows the following:
1% of $80.00 is $ .8010% of $80.00 is $ 8.0025% of $80.00 is $20.00
Using only these benchmarks, he combines these amounts to figure other percentages.
2% of $80.00 is $1.60 (double the 1% amt.)3% of $80.00 is $2.40 (triple the 1% amt.)4% of $80.00 is $3.20 (4 times the 1% amt. or double the 2% amt.)5% of $80.00 is $4.00 (5 times the 1% amt. or half of the 10% amt.)20% of $80.00 is $16.00 (double the 10% amt.)75% of $80.00 is $60.00 (triple the 25% amt.)23% of $80.00 is $18.40 (20% + 3% or $16.00 + $2.40)
Try some!
50% of $80.00 is 30% of $80.00 is
100% of $80.00 is 60% of $80.00 is
90% of $80.00 is 15% of $80.00 is
70% of $80.00 is 9% of $80.00 is
40% of $80.00 is 49% of $80.00 is
12% of $80.00 is 33% of $80.00 is
Make up some of your own.

3. Passing a state budget is a long and complicated procedure. At times this pro-cess can nearly shut down the state government. One year a house of representa-tives rejected the governor‘s budget proposal and developed their own version.There were 74 democrats and 46 republicans in the house that summer.
If 44 democrats and 35 republicans voted to pass the house version of the budgetand all members voted, answer the following questions:
Approximately what percent of the democrats voted yes? ____________
Approximately what percent of the republicans voted yes? ___________
Approximately what percent of all representatives voted yes? ___________

Percentages are used in basketball to indicate a players fieldgoal average. The "Dream Team" worksheet providesstudents with some statistics on well known players. Manyof the percentages will need to be rounded and shouldpromote some discussion.
One of the more interesting ways of involving students in working with percentsis to arrange to show a video of the first half of an actual game. Ask yourbasketball coach if he/she has a video to watch or tape a recent game from acollege or pro team that is televised. Assign each student one or more players towatch and keep a tally of the shots made and shots attempted on the sheetprovided. Follow this activity with a class discussion.

The purpose of the following activity is to familiarize students withthe % mode on a calculators.
Before introducing this activity, a class warm-up might include discussing ways ofwriting down calculator steps for basic arithmetic operations.
Warm-up 1
Say to the class "Add 17 and 8 on your calculator. What answer did youget? Now, write down each step that you took. Be specific."
Examples: 17 + 8 = OR 8 + 17 = OR 17 + 8 +
Warm-up 2
Say to the class, "Multiply 9 and 5 , then subtract 10 from the result. Whatis your answer? Record each step carefully."
Examples: 9 x 5 = - 10 OR 9 x 5 - 10 =
Make up more sample problems as needed. The introductory problem on thefollowing page is intended for students to experiment with their calculators untilthey find a way to use the % key and come up with a correct response. Possiblerecorded steps for this problem are shown below.
49.95 x 40 % =
40 % x 49.95 =
*40 x 49.95 %
*Some students will begin to see that when the % key is used, the decimal pointmoves 2 place; we want to encourage students to act meaningfully.
