Help your sixth graders remember the rules for adding and multiplying positive and negative numbers with this printable algebra activity. Kids are encouraged to think of real-world examples where two negatives make a positive as well as ones where two negatives make a negative. You can then discuss the examples as a class and see how they relate to the algebraic rules.
