Making Change
To calculate the amount of change that should be given: • Subtract the cost from the amount given
Change should be made using the smallest number of bills and coins possible. We do this by counting up.
Example
Marcus bought a new action figure for $17.73. He gave the cashier $20.00. How much change should he receive?
$ Given: $20.00 - Cost: - $17.73 Change: $ 2.27
Practice
Spent $7.25, paid $10.00 $10.00 -$ 7.25= $2.75

Measures of Time
60 seconds = 1 minute 366 days = 1 leap year 60 minutes = 1 hour 12 months = 1 year 24 hours = 1 day 10 years = 1 decade 7 days = 1 week 20 years = 1 score 52 weeks = 1 year 100 years = 1 century 365 days = 1 year 1,000 years = 1 millennium
Practice
60 minutes = 1 hour _60__ seconds = 1 minute
365 days = 1 year 100 years = 1 century _10_ yrs. = 1 decade 1 score = 20 years
Instructional notes

Practice
_3_ ft. = 1 yd. _36_ in. = 1 yd. _12__ in. = 1 ft. _5,280 ft. = 1 mi.
