Study Notes
Long Division Methods
-
Setup: Write the dividend (3 or 4 digit number) under the long division symbol and the divisor (2 digit number) outside.
-
Estimation:
- Determine how many times the divisor fits into the first few digits of the dividend.
- Round the divisor for easier calculations (optional).
-
Division Steps:
- Divide: Find how many times the divisor fits into the leading part of the dividend.
- Multiply: Multiply the divisor by the number obtained in the previous step.
- Subtract: Subtract the result from the current dividend part, bringing down the next digit.
- Repeat: Continue the process until all digits of the dividend have been used.
-
Remainders: If a remainder is left over after the final step, it should be noted.
-
Checking: Multiply the quotient by the divisor and add the remainder to verify correctness.
Word Problems
-
Identify the Dividend and Divisor:
- Read the problem carefully to determine the total amount (dividend) and how it is divided (divisor).
-
Set Up the Equation:
- Formulate the equation based on the context of the problem, e.g., Total Amount ÷ Number of Groups = Amount per Group.
-
Use Long Division:
- Apply long division methods to solve, following the steps outlined above.
-
Interpret the Result:
- Analyze the quotient in the context of the problem.
- Consider whether a remainder is relevant to the solution (e.g., distributing items).
-
Common Scenarios:
- Sharing items equally among people.
- Determining how many items can fit into groups of a set size.
- Calculating costs, distances, or time when divided into parts.
These methods and techniques are essential for solving division problems involving 3 and 4 digit dividends by 2 digit divisors effectively and accurately.
Long Division Setup
- Long division is used to divide a 3 or 4-digit number (the dividend) by a 2-digit number (the divisor).
- The dividend is written under the long division symbol, and the divisor is written outside.
Estimation in Long Division
- Estimate how many times the divisor goes into the first few digits of the dividend.
- Consider rounding the divisor for easier estimation.
Division Steps
- Divide: Find how many times the divisor goes into the leading part of the dividend.
- Multiply: Multiply the divisor by the quotient you found in the previous step.
- Subtract: Subtract the result from the current dividend part, bringing down the next digit.
- Repeat: Continue this process until all digits of the dividend have been used.
Remainders in Long Division
- If a remainder is left over after the final step, it should be recorded.
Checking Long Division
- Multiply the quotient by the divisor.
- Add the remainder to this product.
- If the result matches the original dividend, the long division is correct.
Word Problems Using Long Division
- Dividend and Divisor: Identify the total amount (dividend) and the number of groups or parts (divisor) in the word problem.
- Equation: Formulate an equation based on the problem's context, describing how the dividend is divided.
- Apply Long Division: Use long division to solve the equation.
- Interpretation: Interpret the quotient within the context of the word problem.
- Remainder: Consider if the remainder is relevant to the solution.
-
Scenarios:
- Sharing items equally.
- Finding how many items fit into groups of a set size.
- Calculating costs, distances, or time split into parts.
