Rounding Checker

Rounding depends on the place value you are rounding to, not just the nearest-looking number. This checker asks for the original number, the target place, and the rounded answer. It calculates the nearest value for that place, then compares it with the student response. Decimal places such as tenths, hundredths, and thousandths are supported, along with whole-number places like tens, hundreds, and thousands.

Use this when students are learning which digit to inspect and when to round up. If the answer is wrong, the checker gives the rounded value for the selected place, which helps separate place-value mistakes from basic arithmetic mistakes. It is intentionally narrow: it checks the final rounded number. If a worksheet includes many rounding problems or written explanation, the photo checker below can mark the whole page at once.
