Grade 5 - Number
Standard 5.N.6 - Practice dividing 2 numbers with operands up to 12.
Included Skills: Division
Demonstrate an understanding of division (1- and 2-digit divisors and up to 4-digit dividends), concretely, pictorially, and symbolically, and interpret remainders by • using personal strategies • using the standard algorithm • estimating quotients to solve problems. • Model the division process as equal sharing using base-10 blocks, and record it symbolically. • Explain that the interpretation of a remainder depends on the context: - ignore the remainder (e.g., making teams of 4 from 22 people) - round up the quotient (e.g., the number of five passenger cars required to transport 13 people) - express remainders as fractions (e.g., five apples shared by two people) - express remainders as decimals (e.g., measurement or money) • Model and explain the relationship that exists between algorithm, place value, and number properties. • Determine quotients using the standard algorithm of long division. (The multiples of the divisor are subtracted from the dividend.) • Solve a division problem in context using personal strategies, and record the process. • Refine personal strategies such as mental math strategies to increase efficiency when appropriate (e.g., 860 ÷ 2 think 86 ÷ 2 = 43 then 860 ÷ 2 is 430).
