In this lesson, you will learn how to solve two-step word problems involving multiplication using model drawing techniques. By the end of the lesson, you will be able to identify key words like ‘twice’ and ‘thrice’ that signal multiplication scenarios. We will solve examples including a school enrollment problem and a comparative sales analysis between two mini-marts. Follow the steps: read the problem, circle key words, draw a model, and solve for the answer. Gain confidence in tackling multiplication word problems effectively!

Lesson Objectives: • At the end of the lesson, you will • Solve two-step word problem on multiplication using model drawing. • Identify key words such as ‘twice’, and ‘thrice’ in a multiplication problem.
1) There are 746 boys in a school. The number of girls is twice the number of boys in the school. How many pupils are there altogether in the school ? 746 boys ? girls ? 2 746 x 1492 = 1492 + 746 2238 = There are 2238 pupils altogether in the school.
2) Mini-mart A sold 560 food hampers during Christmas. Mini-mart B sold thrice as many food hampers as Mini-mart A. How many more food hampers did Mini-mart B sell than Mini-mart A? 560 ? Mini-mart A Mini-mart B ? 560 x 3 1680 = 1680 - 560 1120 = Mini-mart B sold 1120 more food hampers than Mini-mart A.
Remember… • Read the problem. • Circle the key words or clues from the problem. • Draw the model. • Solve the problem.
