Decimal Subtraction
1. State the problem: Explain that subtraction of decimals means finding the difference between two decimal numbers.
2. Align the decimals: Teach learners to write the numbers vertically, making sure the decimal points are lined up.
3. Add zeros if needed: If the numbers have different decimal places, add zeros to the shorter number to make the decimal places equal.
4. Subtract from right to left: Start subtracting digits from the rightmost place value (smallest decimal place) moving left.
5. Borrow if necessary: If the top digit is smaller than the bottom digit, borrow 1 from the next left digit.
6. Place the decimal point in the answer: The decimal point in the result should be directly below the decimal points in the numbers.
7. Check the answer: Review the subtraction to ensure accuracy and explain the meaning of the result in context.
