Which technique is effective for teaching place value?

Employing visual aids and manipulatives is an effective technique for teaching place value because these resources make the abstract concept more tangible for students. When learners can physically interact with items such as base-ten blocks or place value charts, they are better able to grasp how numbers are structured and the significance of each digit's position within a number.

Visual aids help in illustrating concepts like ones, tens, hundreds, and so on, enabling students to visualize how numbers are formed and how they relate to one another. Manipulatives, such as counters or blocks, allow for hands-on activities where students can build numbers, compare values, and understand addition and subtraction in terms of place value. This interactive approach fosters deeper understanding, as students can explore, experiment, and engage with the material in a meaningful way.

In contrast, auditory reminders might support memory but do not provide a visual or hands-on experience that is crucial for comprehension. Repetitive lectures and focusing solely on written exercises can lead to rote memorization without ensuring true understanding, as they do not allow for dynamic learning or application of place value concepts in a practical sense.
