Adding and Subtracting with Decimals

To add and subtract with decimal numbers students learn how to use the place value table to align the digits in columns. By fixing the position of the decimal point they gain a secure understanding of each digit’s value, why numbers are carried over for addition and how they can be borrowed when calculating the difference.
Differentiated Learning Objectives
  • All students should be able to add and subtract with decimals using the place value table.
  • Most students should be able to add and subtract with decimals using the written column method.
  • Some students should be able to calculate the difference between a pair of decimals in order to solve problems.
