This is a 4 page set of purposeful practice station work. Includes a page full of ADD 10 more, a page full of SUBTRACT 10 less, a page full of ADD 100 more, and a page full of SUBTRACT 100 less. Each set is designed for you to copy, laminate, and cut the pairs apart. Students will use the station to match pairs. Can be used as a memory game for no assessment or have students match pairs and record the problems on a piece of paper for an informal assessment. Each page can be used by itself as its own practice station or combined with the other cards for a more timely station. Excellent hands-on reinforcement practice!
