# Best Strategies to Solve Math Word Problems l Introduction To Math

TLDRThis video introduces a two-pronged strategy for solving math word problems effectively. First, determine if the answer should be larger or smaller than the initial parts, guiding you to choose between addition/multiplication or subtraction/division. Second, identify signal words that suggest specific operations: 'all together' for addition, 'decrease' for subtraction, 'per' for multiplication, and 'half' for division. By recognizing these clues, viewers can confidently select the correct operation to tackle real-life math challenges.

### Takeaways

- π Identify if the word problem suggests the answer is larger or smaller than the initial parts given; this guides whether to use addition/multiplication or subtraction/division.
- π Look for signal words that indicate specific operations: 'took' and 'how many are left' imply subtraction.
- π Use subtraction in problems where something is taken away from a total, like subtracting slices of pizza taken by Susie from the total.
- π For problems involving multiplication, look for words like 'for each' and 'how many total', as in calculating the total number of notebooks needed for students.
- π Multiplication is often used when dealing with multiples of a quantity, such as notebooks for each student.
- π Signal words for addition include 'all together', 'combined', 'increase', 'sum', 'total', and 'how many more'.
- β Signal words for subtraction are 'decrease', 'difference', 'how many left', 'remain', 'take away', and 'how many more'.
- βοΈ Signal words for multiplication are 'per', 'each', 'times', 'twice', 'triple', 'etc.', and 'total'.
- π Signal words for division include 'half', 'third', 'quarter', 'how many each', 'out of', 'percent', and 'quotient'.
- π§ Knowing the right operation to choose is crucial for solving word problems and applying math in real-life situations.
- π Memorizing these strategies and signal words will empower you to tackle any word problem effectively.

### Q & A

### What is the main focus of the video transcript provided?

-The video transcript focuses on strategies for solving math word problems by identifying key words and phrases that indicate the appropriate mathematical operation to use.

### What is the first strategy mentioned for choosing the right operation in a word problem?

-The first strategy is to determine if the answer to the word problem is likely to be larger or smaller than the initial parts given, which can suggest whether to use addition/multiplication or subtraction/division.

### How does the word 'took' in the pizza example suggest the operation to be used?

-The word 'took' implies that something has been removed or subtracted from the initial amount, indicating that subtraction is the appropriate operation.

### In the notebooks example, what signal words indicate that multiplication is the correct operation?

-The words 'for each' and 'how many total' suggest that the operation involves scaling up the initial quantity (24 students) by a factor (2 notebooks per student), indicating multiplication.

### What are some signal words associated with addition in math word problems?

-Signal words for addition include 'all together', 'combined', 'increase', 'sum', 'total', and 'how many more'.

### What signal words are indicative of the need for subtraction in a word problem?

-Signal words for subtraction include 'decrease', 'difference', 'how many left', 'remain', 'take away', and 'how many more'.

### Can you provide some examples of signal words for multiplication in word problems?

-Examples of signal words for multiplication are 'per', 'each', 'times', 'twice', 'triple', etc., and 'total'.

### What signal words should you look for when division is the required operation in a word problem?

-Signal words for division include 'half', 'third', 'quarter', 'how many each', 'out of', 'percent', and 'quotient'.

### Why is knowing the right operation crucial for solving word problems?

-Knowing the right operation is crucial because it directly affects the solution to the word problem, ensuring accurate results in practical, real-life math situations.

### How can the strategies discussed in the transcript help in real-life situations involving math?

-The strategies help by providing a systematic approach to identifying the necessary operation for solving word problems, which is essential for making correct calculations in everyday scenarios.

### What is the significance of signal words in determining the operation needed to solve a word problem?

-Signal words are significant as they act as cues that guide the problem solver towards the correct mathematical operation, thus helping to avoid errors and solve the problem efficiently.

Word problems often require you to infer the solution method from the text rather than being explicitly told.

A two-pronged strategy is introduced to determine the correct mathematical operation for word problems.

Assess if the answer to the problem is likely larger or smaller than the initial values given to choose between addition/multiplication or subtraction/division.

Look for signal words that suggest specific operations such as 'took' and 'how many are left' indicating subtraction.

In the pizza example, 'took' and 'how many are left' confirm the need for subtraction to find remaining slices.

For the notebooks example, 'for each' and 'how many total' suggest multiplication to calculate the total number needed.

Signal words for addition include 'all together', 'combined', 'increase', 'sum', 'total', and 'how many more'.

Subtraction problems often contain words like 'decrease', 'difference', 'how many left', 'remain', 'take away', and 'how many more'.

Multiplication is indicated by words such as 'per', 'each', 'times', 'twice', 'triple', and 'total'.

Division problems may include signal words like 'half', 'third', 'quarter', 'how many each', 'out of', 'percent', and 'quotient'.

Understanding signal words is crucial for choosing the correct operation to solve word problems effectively.

Practical real-life situations often involve word problems, making these strategies essential for everyday math.

The video provides a structured approach to identifying operations needed for word problems, enhancing problem-solving skills.

Learning to solve word problems is not just about academics but also about navigating everyday math challenges.

Mastering these strategies can help tackle any word problem encountered, promoting confidence in mathematical abilities.

The video concludes with the importance of applying these strategies to real-life scenarios for practical math skills.
