In this Grade 5 Eureka Math lesson from Chapter 6 on Dividing Decimals, students practice solving multi-step word problems using decimal operations including addition and division. Using tape diagrams as visual models, students work through real-world scenarios such as splitting costs equally among friends and distributing money as allowances, applying the standard division algorithm to decimal values. The lesson also reinforces fluency with multiplying and dividing by powers of ten (10¹ through 10⁴) and dividing decimals like 0.3 ÷ 2 using place value understanding.
Section 1
Modeling with Tape Diagrams
A tape diagram models the relationship between a whole (total) and its parts. For problems involving equal groups, this relationship can be expressed as:
This model helps identify the unknown quantity and choose the correct operation to solve for it.
Section 2
Solving Multi-Step Decimal Word Problems
Solving multi-step word problems involves translating the problem's context into a sequence of mathematical operations. The solution is found by performing these operations in the correct order:
Section 3
Dividing a Decimal by a Whole Number
To divide a decimal by a whole number, place the decimal point in the quotient directly above the decimal point in the dividend. Then, divide using the standard algorithm as you would with whole numbers.
