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.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Serving Up Word Problems includes three types of word problems:
Taking From (10 - ? = 6)
Taking Apart (10 - 6 = ?)
Comparing (10 - 4 = ?)
Each type of word problem includes three levels. Level 1 provides subtraction activities within 5. Level 2 provides subtraction activities within 12. Level 3 provides subtraction activities within 20. Students can practice each level using 16 task cards and manipulatives (e.g., Part-Part-Whole mat). Each task card has a corresponding response sheet. Teachers can access 144 response sheets for formative assessments.
