On a separate sheet of paper, illustrate a sea with the following: a crab 5ft. below sea level, a cliff 3 ft. above the sea level, and a flying bird 4 ft. above sea level. Use a vertical number line to help you out in the illustration.
After making the drawing, study it carefully and answer the questions below.
1. What Number might be a good representation for the sea level?
2. How do you represent the distance below and above the sea level?
3. How far is the cliff from the sea level?
4. How far is the bird from the sea level?
5. How far is the crab from the sea level?
6. What is the distance between the cliff and the crab?
7. What is the distance between the bird and the crab?
Learning Task 2
A. Add the following.
1. (+9) + (+10) = 6. (–3) + (–3) =
2. (–7) + (–5) = 7. (+4) + (–8) =
3. (+5) + (–6) = 8. (–8) + (+12) =
4. (+2) + (+8) = 9. (–11) + (+11) =
5. (–1) + (+10) = 10. 0 + (–9) =
B. Subtract the following.
1. (+7) – (+4) = 6. (–4) – (–4) =
2. (–2) – (–6) = 7. (+5) – (+10) =
3. (+10) – (–3) = 8. (–12) – (+7) =
4. (–6) – (+9) = 9. (+8) – (+6) =
5. (–10) – (+1) = 10. 0 – (–9) =
Learning Task 3 . Solve each problem involving integers.
