Unit 7: Lessons 8-10

Andre looks at a box of paper clips. He says: “I think the number of paper clips in the box is less than 1,000.” Lin also looks at the box. She says: “I think the number of paper clips in the box is more than 500.”

Write an inequality to show Andre's statement, using “p” for the number of paper clips.

• P > 500

• P > 1000

• P < 1000

• 500 < P < 1000

Lin says that the inequalities h > 150 and h < 160 describe her height in centimeters. What do the inequalities tell us about her height?

• Lin is greater than 160 cm.

• Lin is less than 150 cm.

• Lin is between 150 and 160 cm.

• Lin is between 0 and 160 cm.

Andre notices that he is a little taller than Lin but is shorter than their math teacher, who is 164 centimeters tall.

Select all heights that could be Andre's height in centimeters.

If you get stuck, consider drawing a number line to help you.
