Worksheet directions

Grade 6 • Independent Practice • Work on your own. Show your calculations or reasoning where needed.

Sample questions

1. A student claims 25.9 + 0.49 = 263.9. Use place value or an estimate to diagnose the decimal-point error and give the correct answer.
2. A student claims 46.3 + 0.85 = 471.5. Use place value or an estimate to diagnose the decimal-point error and give the correct answer.
3. Solve 19.1 + 0.37. Check the result with an inverse operation and explain why the check works.
4. Solve 39.5 + 0.73. Check the result with an inverse operation and explain why the check works.
5. Compute 12.3 + 0.25 using the standard algorithm. Explain how you determine the decimal point in the answer.
6. Compute 32.7 + 0.61 using the standard algorithm. Explain how you determine the decimal point in the answer.
