Real 4th Grade problems, one per topic, from multi-digit multiplication to roman numerals — the same explanations your child sees when practicing online.
Multi-digit Multiplication
Estimate 209 × 4 by rounding 209 to the nearest hundred. What is your estimate?
- Round 209 to the nearest hundred: 209 → 200 (the tens digit is 0, so round down).
- Multiply the rounded numbers. 200 × 4: multiply 2 × 4 = 8, then put back the 2 zeros: 800.
- So the estimate is about 800.
Answer: 800

Rosa ran 8.5 km on Saturday and 5.7 km on Sunday. How many more kilometers did Rosa run on Saturday?
- The question compares two amounts ("how many more"), so subtract the smaller from the larger.
- Line up the decimal points: 8.5 − 5.7. Think in tenths: 85 − 57 = 28 tenths, which is 2.8.
- So the answer is 2.8 kilometers.
Answer: 2.8

What number is CXXVIII?
- Split CXXVIII into place-value groups: C | XX | VIII.
- C = 100, XX = 20 (10 + 10), VIII = 8 (5 + 1 + 1 + 1).
- Add the groups: 100 + 20 + 8 = 128.
- So CXXVIII = 128.
Answer: 128
