Make Change

Count up to find the exact change Example: Price $7.67; Amount given $10.00

Start at $7.67. Count up to $10.00

$7.68 $7.69 $7.70 $7.75 $8.00 $9.00 $10.00 To check the change count the bills and coins from the greatest to least

value

$1.00 $2.00 $2.25 $2.30 $2.31 $2.32 $2.33 So you should receive $2.33 as change

Compare and Order Money Amounts You can use a place value chart to compare money amounts.

Start at left. Look for the first place where the digits are different.

Example: Compare $306.97 and $319.23

The amount $319.23 has more ten dollars than $306.97 So, $319.23 > $306.97

Hundred Dollars

CONFIDENTIAL 12

Compare and Order Money Amounts You can also compare and order the same way you do for whole numbers

Step 1: Line up the decimal points. Compare the three amounts. Step 2: Compare the remaining two amounts. Step 3: Write the money amounts in order from least to greatest.

Example: Compare and order from least to greatest: $7.13, $6.95, $6.89 Step 1:

$7.13$6.95$6.89

7>6, so $7.13 is the greatest number. Step 2:

$6.95$6.89

8<9, so $6.89 is less than $6.95 Step 3:

$6.89$6.95$7.13

CONFIDENTIAL 13

Order from greatest to least: $0.98, $0.86, $0.99 $0.99, $0.98, $0.86

CONFIDENTIAL 14

Round Money You round money the same way you do with whole numbers

Step 1: Find the digit in the dollars place. Step 2: Look at the place to the right of the dollars place. Step 3: If the digit is less than 5, round down. If the digit is 5 or greater,

round up. Example: Round $7.13, $6.89, $6.95

Step 1:$7.13$6.89$6.95

Step 2:$7.13$6.89$6.95

Step 3:$7.13 $7.00$6.89 $7.00$6.95 $7.00

Temperature, Changes and Negative Numbers Temperatures can be below 00F or 00C. These are negative temperatures. You read 20 degrees below zero as - 200F. What is the temperature change from 150F to -50F?

Step 1:Find the change in temperature from 150F to 00F . The change is 150.

Step 2: Find the change in temperature from 00F to -50F. The change is 50.

Step 3: Add the 2 changes. 150 + 50=200.
