Lesson Worksheet: Adding Integers Mathematics • 7th Grade

In this worksheet, we will practice adding positive and negative integers in both abstract and real-world contexts that do not just involve numbers but also units.

Q1:

Evaluate 𝑥+𝑦+𝑧+6 for 𝑥=5, 𝑦=6, and 𝑧=9.

Q2:

Fill in the blank: 8+2=.

Q3:

Elizabeth recorded some temperatures during the day on a number line. At 8:00 am, the temperature was represented by an integer that is the opposite of 7F. At 3:00 pm, the temperature was 2F. Write an integer that describes the change in temperature.

Q4:

During a five-day cold wave, Daniel recorded the temperature each day at noon. The temperature was 9F on Monday, 8F on Tuesday, 7F on Wednesday, 5F on Thursday, and 4F on Friday. The temperature at noon on Saturday was 13F warmer than the temperature on Thursday. What was the temperature on Saturday?
