Worked Example 2
A Fraction Problem
A board is 812 feet long. Dan cuts 3 pieces that are each 134 feet long. How much of the board is left?
- 1Pieces cut: 3 × 134 = 514
- 2Left over: 812 − 514 = 314
Answer: 314 feet
Common Mistakes to Watch For
Stopping after the first step
Wrong:Kim's change is $8.25.
$8.25 is the cost of the notebooks. Add the pen, then subtract from $20: $10.26.
Lining up decimals by the last digit
Wrong:8.25 + 1.49 = 8.374
Line up the decimal points: 8.25 + 1.49 = 9.74.
Helpful Math Tip
Have your child list the steps in words first ("find the cost of the notebooks, add the pen, subtract from 20"), then do the math.
