Sample Sections and Sample Problems with Solutions
Number and Number Sense
Sample Problem:
Estimate the sum of 347 and 489.
Answer Key Explanation:
To estimate, round each number to the nearest ten or hundred:
- 347 rounds to 350
- 489 rounds to 490
Add the estimates: 350 + 490 = 840
Estimated sum: 840
Precise Calculation:
- 347 + 489 = 836
Conclusion:
The estimate (840) is close to the actual sum (836), demonstrating the usefulness of estimation in checking answers.
---
Addition and Subtraction
Sample Problem:
Subtract 256 from 738.
Answer Key Explanation:
Step 1: Align the numbers by place value.
Step 2: Subtract units: 8 - 6 = 2
Step 3: Subtract tens: 3 - 5 — since 3 is less than 5, borrow 1 from hundreds.
- Borrow 1 hundred (which is 100), leaving hundreds digit as 6, and tens digit as 13.
- Now, 13 - 5 = 8
Step 4: Subtract hundreds: 6 - 2 = 4
Final answer: 482
---
Multiplication
Sample Problem:
Multiply 23 by 4.
Answer Key Explanation:
Use standard multiplication:
23 × 4 = (20 + 3) × 4 = (20 × 4) + (3 × 4) = 80 + 12 = 92
Alternative Method:
Use the grid method or lattice multiplication for visual learners.
---
Fractions
Sample Problem:
Shade 3/4 of a rectangle divided into 4 equal parts.
Answer Key Explanation:
- Divide the rectangle into 4 equal parts.
- Shade 3 of these parts to represent 3/4.
- Confirm that the shaded parts are contiguous or scattered, depending on the question's specifics.
