This is a fun, hands-on approach to teach number sense and the concept of story problems. Use the pond or corral story mats with 10-frame squares or without. Students will love telling the stories and writing down their number sentences on the corresponding recording sheet. When their ability increases they can learn to write their stories down on the accompanying sheet. There are 16 addition and 16 subtraction story problem cards with the pond or corral theme for students to use with the mats or as a game by themselves.
