This math unit begins with enhancing students' understanding of basic division by powers of ten, emphasizing the adjustment of decimal places when dealing with positive integers. Progressing deeper into the unit, students learn to handle divisions involving decimals and negative powers of ten, further challenging their ability to manipulate decimal values effectively. Fractional representations of division are introduced to solidify comprehension of decimal interactions. Later, the unit transitions into long division where the results are decimals, aiming to solidify manual calculation skills and precision with remainders. Pivoting towards scientific notation, students then practice multiplying decimals by powers of ten, preparing them for converting numbers in scientific notation to standard decimal forms. This gradually escalates in complexity from zero to two decimal places, enhancing students' accuracy and understanding of scaling numbers by powers of ten. The unit culminates with exercises on dividing whole numbers by decimal tenths, reinforcing a comprehensive grasp of decimal division concepts throughout various practical scenarios.
