In this Grade 5 Eureka Math lesson from Chapter 13, students learn to divide decimal dividends by two-digit divisors using the standard algorithm, including estimating quotients and reasoning about decimal point placement. Students also explore how whole-number division connects to decimal division by examining problems with identical quotients and remainders that represent different values. The lesson builds fluency with renaming tenths and hundredths in unit form as a strategy for applying whole-number division skills to multi-digit decimal division.
Section 1
Dividing Decimals Using the Standard Algorithm
To divide a decimal dividend by a whole number divisor, place the decimal point in the quotient directly above the decimal point in the dividend.
Then, perform the division as you would with whole numbers.
Section 2
Solving Multi-Step Decimal Division Word Problems
To solve a multi-step word problem, first identify the sequence of operations required (e.g., addition, subtraction, multiplication) and then perform the decimal division.
Break the problem down into smaller, single-step parts to find the final answer.
