Number sense
Number sense is a foundational concept in mathematics education that encompasses a student's ability to understand and manipulate numbers in various contexts. It is recognized as crucial for academic success, particularly in early childhood education, where it is a focus from kindergarten through second grade. Studies indicate that individuals may possess an innate number sense, with toddlers displaying the capability to recognize small quantities without formal counting. As children grow, their interactions with numbers significantly enhance their number sense, allowing them to approach mathematical problems more flexibly and strategically.
Research has shown that children with strong number sense are better at estimating, recognizing patterns, and breaking down complex problems into manageable parts. In contrast, those with weaker number sense often rely on rigid procedural methods. Parents and educators play a vital role in developing number sense by engaging children in activities that involve counting, estimating, and exploring numerical relationships. This interactive approach not only fosters a deeper understanding of numbers but also prepares children for future mathematical challenges. Overall, nurturing number sense is seen as essential for lifelong mathematical competence and problem-solving skills.

Number sense
Number sense is a concept in mathematics education. It refers to a student's ability to understand and work with numbers in various ways. For example, students may be able to demonstrate multiple strategies for solving the same problem. In the twenty-first century, math educators believe that number sense is of utmost importance, and it has become a focus of math education in kindergarten through second grade.
Overview
Experts believe that people are born with an intuitive sense of numbers. Toddlers have demonstrated the ability to recognize groups of one, two, or three objects before they are able to count. Additionally, a 2019 study conducted by researchers at Johns Hopkins University showed that children as young as fourteen months have the ability to associate quantity with counting despite not yet having an understanding of the concept of numbers. In this experiment, the findings of which were published in the journal Developmental Science, the researchers discovered that when children were shown objects that were counted out loud before being hidden, they could better remember the number of objects involved. Over time, as their brains continue to develop, they are able to recognize groups of four or five without counting. The more people interact with and explore numbers, the sharper their number sense becomes. In the twenty-first century, math educators have made number sense a key focus of mathematics education.
A 2022 study published in the Journal of Neuroscience points out that good number sense in early childhood is often predictive of academic success, while deficits in number sense often continue throughout life, developing into lifelong impairments in mathematical abilities. The researchers identified a brain circuit that plays an important role in whether a child is born with the ability to develop good number sense. According to the researchers, this gave important insights into children's differences when learning about numbers. They hoped that studying this brain circuit would lead to the development of effective interventions to remedy learning disabilities.
Experts had already noted a difference in how students approach solving mathematical problems. Students with poor number sense tend to rely on procedures for solving problems, even if that procedure is not the easiest way to reach a solution. They prefer to work out problems on paper using a step-by-step process rather than make mental calculations. Students with good number sense use numbers more flexibly. They depend less on formal procedures and may use a range of strategies to solve a problem. They may break difficult math problems into a few smaller, easier-to-solve pieces. For example, they might break the problem 14 × 7 into two simpler problems—10 × 7 and 4 × 7—and add these two solutions together. Students with good number sense are able to make reasonable estimations before solving a problem. They demonstrate an understanding of magnitude—greater than, less than, bigger, smaller—and they quickly and easily recognize number patterns and relationships between numbers.
Parents can help their children develop their number sense by creating opportunities for children to interact with numbers. For example, they might encourage their children to count the number of plates and the number of pieces of silverware on the dinner table. Then they might ask them, "Which number is greater?" or "How many plates are left if I take one away?" They can encourage children to practice estimating by asking, "About how many pretzels are in the jar?" or "About how much lemonade is in the pitcher?" The more parents engage children in conversations about numbers, the more comfortable children will become with them.
Teachers can develop their students' number sense using several strategies. One strategy is to demonstrate various ways to solve the same problem. The teacher may invite the class to make suggestions to further encourage discussions of numbers and number relationships. Another strategy is to pose problems with multiple answers. For example, teachers can present students with a group of numbers and ask them to identify the number that is not like the others. Such a problem requires students to think about the relationships among all the numbers in the group and consider all the ways in which they are alike and different. Encouraging mental math and estimation are other tools teachers can use to improve students' number sense.
