This worksheet consists of a set of questions on addition and subtraction where students are required to add and subtract tenths and hundredths without regrouping. Students understand that when adding or subtracting decimals, it is important to align the decimal points and use zeros as placeholders. In this worksheet, they find the answer without regrouping. In this worksheet, numbers are laid one on top of another (vertical format). This encourages students to use the inherent place value structure to solve the problems.
