Mastering Integer Word Problems

The video tutorial covers multiplying and dividing integers through word problems. It begins with a football team losing yards over consecutive plays, demonstrating multiplication of negative integers. A model is used to visualize the process. The tutorial then shifts to a division problem involving temperature change, illustrating how to divide negative integers. Key strategies include identifying important information and using models for better understanding.

What is the first step in solving a word problem involving integers?

• Guess the answer

• Draw a model

• Highlight or underline the question

• Write down the numbers
