Weight and Ordering Problems

This lesson in illustrative math focuses on modeling with inequalities. It includes two main activities: determining the number of sandwiches that can be ordered with a given budget and calculating how many boxes can be loaded onto an elevator without exceeding its weight limit. The lesson emphasizes understanding and applying inequalities to solve real-world problems.

What is the main learning target of the lesson on modeling with inequalities?

• To calculate the weight of boxes

• To solve real-world problems using inequalities

• To learn about sandwich ordering

• To understand the concept of inequalities

If sandwiches cost $5.99 each, how many can be ordered with $83?

• 13 sandwiches

• 12 sandwiches

• 14 sandwiches

• 15 sandwiches

Why can't the stage manager order exactly 13.86 sandwiches?

• Because the price is too high

• Because the shop is closed

• Because sandwiches are not available

• Because you can't order a fraction of a sandwich

Which of the following is a valid statement about the number of sandwiches that can be ordered?

• Ordering 9.5 sandwiches

• Ordering 13.86 sandwiches

• Ordering 14 sandwiches

• Ordering -4 sandwiches

What is the maximum weight the elevator can carry?

• 2000 pounds

• 2500 pounds

• 3000 pounds

• 1500 pounds

How much does each box weigh in the elevator activity?

• 50 pounds

• 48 pounds

• 40 pounds

• 45 pounds

What is the weight of the mover in the elevator activity?

• 185 pounds

• 175 pounds

• 200 pounds

• 150 pounds

How many boxes can be loaded on the elevator without exceeding the weight limit?

• 36 boxes

• 37 boxes

• 39 boxes

• 38 boxes

Why can't 37.8125 boxes be loaded on the elevator?

• Because the mover is too heavy

• Because the boxes are too heavy

• Because you can't load a fraction of a box

• Because the elevator is broken

What should students do after watching the lesson video?

• Load boxes onto an elevator

• Order sandwiches

• Review the material and prepare for the next lesson

• Ignore the video
