Word Problems — Using Math in God's World

Memory Verse "Suppose one of you wants to build a tower. Won't you first sit down and estimate the cost to see if you have enough money to complete it?" — Luke 14:28 (NIV)

Learning Objective

Students will solve real-world word problems using multiplication and division.

Lesson Content

Jesus told a story about a man who wanted to build a tower. Before he started, he sat down and counted the cost. Math helps us plan, solve problems, and make wise decisions — just as Jesus taught!

When you see a word problem, first decide: is this multiplication or division? If you are combining equal groups, multiply. If you are splitting into equal groups or finding how many groups, divide.

Here is a multiplication problem: 'A farmer plants 6 rows of corn with 8 stalks in each row. How many corn stalks are there?' We multiply: 6 × 8 = 48 corn stalks.

Here is a division problem: 'A church has 36 Bibles to share equally among 9 classrooms. How many Bibles does each classroom get?' We divide: 36 ÷ 9 = 4 Bibles each.

Some problems need both operations! 'Mom bakes 24 cookies and divides them into 4 bags. Then she buys 3 more bags with 6 cookies each. How many cookies does she have in all?' First: 24 ÷ 4 = 6 per bag. Then: 3 × 6 = 18 more. Total: 24 + 18 = 42 cookies.

Hands-On Activity

Write and solve three word problems of your own — one using multiplication, one using division, and one using both. Trade with a classmate and solve each other's problems.

Discussion Questions

  • How do you decide whether to multiply or divide in a word problem?
  • Can you think of a time when you needed math to solve a problem at home?
  • Why did Jesus say it is wise to plan ahead and count the cost?
