Understanding Multiplication in Word Problems
Property
To solve a word problem using multiplication, identify the number of equal groups and the size of each group.
The total amount can be found using the equation:
In this Grade 4 Pengi Math lesson from Chapter 4, students learn how to interpret remainders in real-world contexts by deciding whether to round up, drop, or share them depending on the situation. They use tape diagrams to solve multiplicative comparison problems and tackle multi-step word problems involving all four operations. Students also practice deconstructing word problems to uncover hidden questions and determine the correct sequence of operations.

The total amount can be found using the equation:
Section 2
Interpreting Remainders in Division Word Problems
When solving a division word problem, the quotient is the number of equal groups, and the remainder is the amount left over. The final answer depends on how the question asks you to interpret this remainder: either ignore it, use it to round up the quotient, or use the remainder itself as the answer.
The bakery can make 208 full cakes. The remainder of 2 eggs is ignored.
302 buses are needed. 301 buses will be full, and one extra bus is needed for the remaining 7 students.
There will be 2 apples left over. The remainder is the answer.
This skill involves solving division word problems where the dividend is a four-digit number and the divisor is a one-digit number. After performing the long division, you must carefully read the question to understand what to do with the remainder. Sometimes the answer is the quotient, sometimes you need to add one to the quotient, and other times the remainder itself is the answer. The context of the story problem is the key to finding the correct solution.
