Place value systems represent numbers using positional notation, with the value of each digit dependent on its place. However, place value is very abstract for young students. Seeing each place as a shape provides a visual foundation for number sense. Representing numbers as combinations of cubes, squares, and other shapes for each place makes place value more concrete and intuitive to understand. This place shape method works for any number system, not just base ten, and can help students more easily grasp formulas, algebraic manipulation, and advanced math concepts.
