Math Extensions allow students to play an active role in their learning. The activities in this resource can be used to introduce or practice the Georgia Standards of Excellence:
MGSE1.OA.6 Add and subtract within 20.
b. Fluently add and subtract within 10.
The standard expects first graders to fluently add within 10. However, this resource has three levels. The first level includes addition facts within 5. The second level includes addition facts within 10. The third level includes addition facts within 20.
Each level is paired with a response sheet. Teachers can use the response sheets as formative assessments.
