Decimals worksheets for Grade 3 (Elementary School)
What this unit covers
Decimals are understood as so many units of 0.1, and addition and subtraction are carried out in column form. The work extends to cases that carry and borrow, and Fill in the Blank plus word problems such as Addition (Comparing) and Subtraction (Comparing) tie each situation to an expression.
Lining up the right-hand ends in the column instead of the decimal points is the standout error, turning 2.5 + 13 into something like 3.8. Check whether the decimal points sit in a straight line. Presentation trips children up too, as when 1.0 is not rewritten as 1, or 0.5 is written as .5.
