📚 Topic Summary
Multiplying decimals by whole numbers using models involves visualizing the decimal as a concrete representation, like a shaded grid. Each part of the grid represents a decimal value, and by combining multiple grids (the whole number), we can visually determine the product. This method helps build a strong understanding of what it means to multiply a decimal.
Essentially, you are adding the same decimal value multiple times, as many times as the whole number indicates. Think of it like repeated addition but with decimals! This approach makes abstract concepts easier to grasp.
