Parents and teachers should prioritize the 2.NBT.B.6 standard, which focuses on adding and subtracting within 100 using concrete models, drawings, or emerging strategies. Understanding this concept is crucial for several reasons.

Firstly, mastering addition and subtraction within 100 lays a strong mathematical foundation for students. This knowledge is essential not only for subsequent grades but also for real-life situations, as these operations are frequently used for budgeting, shopping, and time management.

Secondly, this standard encourages the development of number sense. When children learn to visualize numbers and use concrete models, they enhance their ability to manipulate numbers mentally, fostering more advanced math skills as they progress.

Moreover, by solving problems using different strategies—like decomposition or regrouping—students develop critical thinking and problem-solving skills. Supporting them in this area enables differentiation to meet individual learning needs, ensuring all children can succeed.

Lastly, parent and teacher collaboration is vital. Regularly practicing these skills at home reinforces classroom learning, creating a consistent educational experience. By emphasizing 2.NBT.B.6, adults help students build the confidence and competence needed to thrive in math and beyond.
