What practice enhances numerical fluency according to Mathnasium guidelines?

Using mental math is a key practice that enhances numerical fluency as it helps students develop their ability to understand and manipulate numbers in their heads. This approach encourages quick recall of basic arithmetic facts and reinforces number sense, which is essential for problem-solving and understanding more complex mathematical concepts.

Mental math promotes confidence in students' mathematical abilities, allowing them to perform calculations quickly and accurately without relying on external tools like calculators. It builds a strong foundation by enabling learners to visualize numbers and their relationships, ultimately aiding them in various mathematical scenarios encountered in everyday life and academic contexts. This practice is highly recommended in mathematical education because it fosters deeper cognitive connections with numbers and operational understanding.
