Big Ideas: Each time you divide a decimal by power of ten, the digits in the quotient shift to the right. Fifth grade is the first year students’ encounter dividing by powers of ten with decimal numbers. Students should have the opportunity to reason about dividing a decimal by a power of ten. Students need to be provided with opportunities to explore this concept and come to this understanding; this should not just be taught as a procedure. Vocabulary: exponent, powers of ten, division, quotient, expanded form, standard form Special Materials: place value chart
