This is a tiered activity, which involves adding and subtracting decimals with different place values.
Cards 1-8 are word problems, which are more difficult and some are multi-step. Each set of decimals has different place values so students can practice lining them up.
Cards 9-16 are numerical problems, which are easier, but have different place values and must be lined up.
Students may work in groups to solve the problems. The questions can be cut up into task cards.
There is an Activity Log that can be turned in for a grade.
There is also an Answer Key.
