The purpose of this task is for students to notice how the decimal point behaves when numbers in the same place (both in the hundreds, both in the thousandths, etc) are multiplied, and might be followed by the task 12 Rectangular Units. It leverages students' understanding from grade 5 about patterns in the number of zeros of a product when multiplying by powers of 10 and patterns in the placement of a decimal point when a decimal is multiplied by a power of 10. With this task, we make sure that work is attached to a visual to set students up to understand multiplying any number of decimals.
