A great resource to consolidate rounding to decimal places, this worksheet begins with section A asking three retrieval-style questions on place value.
Section B then provides a table with values to round to 1, 2 and 3 decimal places.
Section C then has some mixed questions on rounding to 1, 2, 3 or 4 decimals.
Section D can then be used as a discussion activity where learners can provide their questions to round to the given values.
