Adding and Subtracting Decimals - Practice 2
These worksheets will help your students practice their decimal addition and subtraction skills. The first sheet is set out with helpful divides to assist your students in layout. The second sheet gets a little trickier by removing these guides and introducing questions with different numbers of decimal places.
These worksheets are part of a larger unit that was written to help your Year 6 students add and subtract decimals and develop estimates through rounding to check their answers.
