We start students thinking about the concept of what a decimal is by presenting the values in fraction form. This is then transferred to using a numbers line and showing the movement of an addition build on that line. Two of the worksheets provide students with a completely functional numbers line so that they may highlight the visual movement of a decimal sum to the tenths.
The worksheets provide students with a variety of techniques for solving decimal addition and subtraction problems, including converting to fractions and using a decimal number line.
