Equations
• Before he went to work, Paul has $24.50. He earned
$12.50 more putting up a fence. Paul had a total of how
much after work?
• Identify the equation pattern.
• Write the equation
• S+M=T
• $24.50 + $12.50 = T
Addition Pattern
• Kate had 734 stamps in her collection. Then her uncle
gave her some more stamps. Now Kate has 813
stamps. How many stamps did Kate’s uncle give her?
• Identify the pattern
• Write the equation
• S+M=T
• 734 stamps + B = 813 stamps
Addition Pattern
• Waverly took $37.00 to the music store. She bought
headphones for $26.17. How much money did Waverly
have remaining?
• Identify the pattern.
• Write the equation.
• B–A=R
• $37.00 - $26.17 = R
Subtraction Pattern
• Jenny rode her bike on a trip with her bicycling club.
After the first day Jenny’s trip odometer showed
that she had traveled 86 miles. After the second
day the trip odometer showed that she had traveled
a total of 163 miles. How far did Jenny ride the
second day?
• S+M=T
• 86 miles + m miles = 163 miles
Addition Pattern
• How many years were there from 1066 to 1215?
•
•
•
•
Subtraction Pattern
L–E=D
1215 – 1066 = Y
Y = 149 years
• The first week 77,000 fans came to the stadium. Only
49,600 came the second week. How many fewer fans
came to the stadium the second week?
•
•
•
•
Subtraction Pattern
L–S=D
77,000 – 49,600 = F
F = 27,400
• Beverly bought two dozen juice bars for 18¢ each. How
much did she pay for all the juice bars?
•
•
•
•
Multiplication Pattern
NxG=T
24 x $0.18 = M
M = $4.32
• Every day Arnold did the same number of push-ups. If
he did 1225 push-ups in one week, then how many
push-ups did he do each day?
•
•
•
•
Multiplication Pattern
NxG=T
7 x P = 1225
P = 175 push-ups
• The beach balls were packed 12 in each case. If 75
cases were delivered, how many beach balls were there
in all?
•
•
•
•
Multiplication Pattern
NxG=T
75 x 12 = B
B = 900
• Only 39 % of the lights were on. What percent of the
lights were off?
•
•
•
•
Addition Pattern
P1 + P2 = W
39% + N = 100%
N = 61%
• The farmer harvested 9000 bushels of grain from 60
acres. The crop produced an average of how many
bushels of grain for each acre?
•
•
•
•
Multiplication Pattern
NxG=T
60C = 9000
C = 150
• Three twentieths of the test answers were incorrect.
What fraction of the answers were correct?
•
•
•
•
Addition Pattern
P1 + P2 = W
3/20 + F = 20/20
F = 17/20
