Math

This morning we did a sheet on Identifying The Extra Information.
Example:
                                    The average weight of a peanut is 0.35 lbs
                                    The average weight of a walnut is 0.80 lbs
                                    The average weight of a small rock is 1.5 lbs
                                     What is the total weight of the peanut and the walnut?

Extra info: The average weight of a small rock is 1.5 lbs
