Multiplying Decimals With Partial Products

Students have been hard at work deepening their understanding of multiplication and numbers by working on understanding the partial products algorithm and how it is tied to the area model. By being able to things of numbers as a representation of their actual value, students are having a better understanding of what happens when we multiply numbers by different values. For example, if we multiply 0.3 by 0.8, we are able to know that our answer will be in the hundredths. We can quickly then multiply 8×3 = 24, and we know that the product is 24 hundredths, or 0.24. Below are some pictures of the students walking their partners through the steps of how to find the exact product.
