Parents and teachers should care about the 2.NBT.B.7 standard in the Number and Operations in Base Ten domain because it lays a crucial foundation for children's mathematical understanding. This standard requires students to "add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction." Mastery of this concept supports not just arithmetic skills but also enhances problem-solving abilities.

Understanding place value is vital for more complex mathematics that students will encounter in higher grades. By grasping how numbers are composed of tens and ones, children develop the ability to group and manipulate numbers effectively. This forms the cornerstone for topics such as regrouping during addition and subtraction, understanding the equalities in math, and starting to work with larger numbers.

Furthermore, proficiency in these skills contributes to academic confidence and engagement. When students positively experience success in math early on, they are more likely to develop a love for learning and mathematics specifically. Parents and teachers play a pivotal role in reinforcing these skills through practice and encouragement, therefore fostering a supportive environment for mathematical growth. Overall, nurturing 2.NBT.B.7 builds essential cognitive skills that benefit students throughout their educational journey.
