Original rope: 10 feet
Cut off: 4 feet
Question: How long is the remaining rope?
This is a subtraction word problem. We need to find what remains after cutting off part of the rope.
Tom starts with 10 feet of rope and cuts off 4 feet.
10 feet (original) and 4 feet (cut off)
Since Tom is cutting off rope, we subtract: 10 - 4
10 - 4 = 6
The remaining piece of rope is 6 feet long.
The remaining piece of rope is 6 feet long.
• Subtraction Rule: When something is taken away, subtract
• Subtraction: 10 - 4 = 6
• Unit Consistency: Both measurements are in feet
Apples: 5 pounds
Oranges: 3 pounds
Question: Total pounds of fruit?
This is an addition word problem. We need to combine two weights to find the total.
Mom bought 5 pounds of apples and 3 pounds of oranges.
5 pounds (apples) and 3 pounds (oranges)
Since we want the total, we add: 5 + 3
5 + 3 = 8
Mom bought 8 pounds of fruit altogether.
Mom bought 8 pounds of fruit altogether.
• Addition Rule: When combining amounts, add them together
• Addition: 5 + 3 = 8
• Unit Consistency: Both measurements are in pounds
Started with: 7 cups
Left over: 3 cups
Question: How many cups were served?
This is a subtraction word problem. We need to find what was taken away from the original amount.
The jug started with 7 cups and ended with 3 cups.
7 cups (original) and 3 cups (remaining)
To find what was served, subtract: 7 - 3
7 - 3 = 4
4 cups of juice were served to guests.
4 cups of juice were served to guests.
• Subtraction Rule: To find what was taken away, subtract remaining from original
• Subtraction: 7 - 3 = 4
• Unit Consistency: All measurements are in cups
Sarah's time: 20 minutes
Brother's time: 15 minutes
Question: How much longer did Sarah practice?
This is a comparison word problem. We need to find the difference between two times.
Sarah practiced for 20 minutes, her brother for 15 minutes.
20 minutes (Sarah) and 15 minutes (Brother)
To find the difference, subtract: 20 - 15
20 - 15 = 5
Sarah practiced 5 minutes longer than her brother.
Sarah practiced 5 minutes longer than her brother.
• Comparison Rule: To find how much more/longer, subtract the smaller from the larger
• Subtraction: 20 - 15 = 5
• Unit Consistency: Both times are in minutes
Original ribbon: 12 inches
First cut: 3 inches
Second cut: 5 inches
Question: How long is the remaining ribbon?
This is a multi-step subtraction problem. First add the cuts together, then subtract from the original length.
Lisa starts with 12 inches, cuts 3 inches, then cuts 5 more inches.
Total cut = First cut + Second cut = 3 + 5 = 8 inches
Remaining = Original - Total cut = 12 - 8 = 4 inches
The remaining piece of ribbon is 4 inches long.
The remaining piece of ribbon is 4 inches long.
• Addition Rule: Combine multiple subtractions first: 3 + 5 = 8
• Subtraction Rule: 12 - 8 = 4
• Multi-step Process: Solve one operation at a time
