Number Pieces helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students can:
- Use number pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide.
- Use edge pieces to display the dimensions of arrays created with number pieces.
- Use the drawing and math text tools to label representations and show their understanding.
