- Find the total number of books initially in the library
- Subtract the number of books checked out
- Calculate the remaining books
- Verify the answer is reasonable
245 + 178 + 89 = 512 books total in library
512 - 125 = 387 books remaining
387 + 125 = 512 ✓ (original total)
Starting with ~500 books and removing 125 leaves ~387, which makes sense
There are 387 books remaining in the library.
• Problem decomposition: Break complex problems into manageable steps
• Operation sequence: Add first, then subtract
• Verification: Use inverse operations to check answers
Geometry applications: Using geometric formulas to solve real-world problems involving perimeter, area, and cost calculations.
Perimeter = 2 × (length + width) = 2 × (24 + 16) = 2 × 40 = 80 feet
Cost = Perimeter × Price per foot = 80 × $4 = $320
Area = length × width = 24 × 16 = 384 square feet
80 × 4 = 320 and 24 × 16 = 384 ✓
The cost to fence the playground is $320, and the area is 384 square feet.
• Perimeter formula: P = 2(l + w) for rectangles
• Area formula: A = l × w for rectangles
• Unit consistency: Maintain proper units throughout calculations
Fraction applications: Using fraction operations to analyze data and determine parts of a whole in real-world contexts.
3/8 + 2/8 + ? = 8/8 (whole), so ? = 8/8 - 3/8 - 2/8 = 3/8
Soccer: 3/8 × 24 = 9 students, Basketball: 2/8 × 24 = 6 students
Swimming: 3/8 × 24 = 9 students, or 24 - 9 - 6 = 9 students
9 + 6 + 9 = 24 students total ✓, and 3/8 + 2/8 + 3/8 = 8/8 ✓
3/8 of students chose swimming. Soccer: 9 students, Basketball: 6 students, Swimming: 9 students.
• Fraction addition: Same denominators, add numerators
• Fraction of whole: Multiply fraction by total to find part
• Data verification: All parts should equal the whole
Pattern recognition & data analysis: Identifying numerical patterns and calculating statistical measures to interpret information.
Jan: 24, Feb: 28 (+4), Mar: 32 (+4), Apr: 36 (+4), so May: 40 (+4)
Total books: 24 + 28 + 32 + 36 + 40 = 160 books
Average = Total ÷ Number of months = 160 ÷ 5 = 32 books per month
Pattern: +4 each month, Average: 32 is reasonable given the range 24-40
40 books will be read in May, and the average is 32 books per month.
• Pattern recognition: Look for consistent differences between consecutive terms
• Average calculation: Sum of all values divided by number of values
• Data prediction: Extend patterns logically based on observed trends
Money & time applications: Integrating decimal operations with multiplication and division to solve real-world financial planning problems.
$3.25 × 8 weeks = $26.00 saved
$12.50 + $4.75 = $17.25 spent
$26.00 - $17.25 = $8.75 remaining
$20 ÷ $3.25 = 6.15... ≈ 7 weeks (round up since partial weeks count as full weeks)
Emma has $8.75 left, and it will take 7 more weeks to save $20 more.
