1.OA.6 Task Cards 1.OA.5, Addition and Subtraction within 20 Task Cards:

These 96 UNIQUE TASK CARDS are aligned with Common Core Standards 1.OA.5 and 1.OA.6: Adding and Subtracting within 20. Several types of questions help you assess your students' mastery of adding and subtracting within 20.

1.OA.5. Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

1.OA.6. Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Task cards are great for a whole-class game, math centers/stations, fast finishers, extra practice, homework, scavenger hunt, quiz-quiz-trade, morning work, small groups, or review for test.

Each card is numbered for your convenience, and there is a student recording sheet and an answer key included. The cards also include the CCSS in the lower left-hand corner. All task cards are included in color and in black and white for your printing needs.
