Understanding Comparisons in Word Problems

The video tutorial teaches how to solve word problems using the comparing model approach. It covers two main examples: one involving masks made by Paul and Joshua, and another involving bowling scores of Rosa and Mark. The tutorial explains the concept of 'fewer than' and 'more than' in comparisons, and demonstrates how to use models and calculations to find solutions. The video concludes with encouragement to keep learning.

What is the main focus of today's lesson?

• Learning about fractions

• Solving algebraic equations

• Understanding geometry

• Solving word problems using the comparing model approach

How many masks did Paul make?

• 123

• 87

• 87 fewer than Joshua

• 210

What does 'fewer than' imply in the context of Paul's and Joshua's masks?

• Paul made more masks than Joshua

• Joshua made fewer masks than Paul

• Paul made fewer masks than Joshua

• Joshua and Paul made the same number of masks

How do we calculate the number of masks Joshua made?

• By subtracting 87 from 123

• By adding 87 to 123

• By multiplying 123 by 87

• By dividing 123 by 87

What is the total number of masks Joshua made?

• 87

• 210

• 123

• 300

How many points did Rosa score in the bowling contest?

• 157

• 824

• 667

• 157 more than Mark

What does 'more than' imply in the context of Rosa's and Mark's scores?

• Rosa and Mark scored the same points

• Rosa scored fewer points than Mark

• Mark scored more points than Rosa

• Rosa scored more points than Mark

How do we calculate the number of points Mark scored?

• By multiplying 824 by 157

• By dividing 824 by 157

• By adding 157 to 824

• By subtracting 157 from 824

What is the total number of points Mark scored?

• 157

• 667

• 824

• 981
