CCSS.MATH.CONTENT.2.NBT.B.5 emphasizes the fluent addition and subtraction of numbers within 100. At this stage, students are expected to leverage their understanding of place value, the inherent properties of mathematical operations, and the interplay between addition and subtraction. For example, knowing that 8 + 2 = 10 can help in understanding that 10 – 2 = 8.
