1.NBT.2 Task Cards: Two-Digit Numbers Task Cards 1NBT2: First-Grade Math Centers:

These 96 unique task cards are aligned with Common Core Standard 1.NBT.2: Two-Digit Numbers. Several types of questions help you assess your students' mastery of two-digit numbers.

1.NBT.2.Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:

10 can be thought of as a bundle of ten ones — called a "ten."

The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.

The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

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.
