This product was designed to meet Common Core Standard 3.NBT.2 for third grade. The focus is on adding and subtracting within 1000. Students will use their knowledge of place value to add, subtract, and work with fact families.
There are 24 task cards and an answer key included in this download. These can be printed on card stock and laminated. One option for use is to have cards placed in a math station. An alternative is to place the cards around the room and have students rotate and solve. I have used these cards for independent and partner work by having students write the answers in their math journals. These also work well for early finishers.
