Rounding replaces a number with a nearby, simpler one (to the nearest ten, hundred, etc.) to make estimating and mental maths easier.
In class: Use a number line to see which ten/hundred a number is closest to. Underline the rounding digit and check the digit to its right.
This Grade 3 rounding set is free to print or save as a PDF, and its answer key is computed in code, so it is never wrong.
