Try a new approach to addition and subtraction by giving scholars the numbers but leaving out the sign. They must determine if the numbers have been added or subtracted, then write in the appropriate operation. There are a few examples here, and scholars complete 24 on their own. Half of these are simply numbers and half incorporate measurement units to show an application. All have double-digit numerals. There are also four word problems.
