This can be used as a whole group independent practice activity as well as a center activity.
Cut out numbers 0-10 or 0-20 based on your objective and tape/glue them to a brown bag. These will represent the sums and/or differences. Pass out the addition or subtraction cards to each student. Students can then move throughout the room, placing their card into the bag marked with the sum/difference of their equation. This can then be used as a center.
