Mathematics for Exam Questions SS1 Third Term

Introduction to Mathematics as a School Subject

Mathematics as a school subject is the study of numbers, shapes, patterns, and the relationships between them. It helps students to develop skills in reasoning, problem-solving, and logical thinking. Mathematics covers topics such as arithmetic, algebra, geometry, statistics, and calculus, depending on the level of study.

In school, Mathematics is not just about calculations — it trains the mind to think in an orderly and precise way. It is also a key subject because it is applied in science, technology, finance, engineering, and everyday decision-making. Mastering Mathematics builds confidence and prepares students for further studies and careers that require analytical skills.

So here you have the answers to the objective section of Mathematics Exam Questions for SS1 Third term. Use the comments section to let me know if you have any questions you would want me to clarify or discuss further.

Answers to Section B (Theory)

1. a. A sector of a circle of radius 4.2cm subtends an angle of 240° at the center.

i. Perimeter of the sector:
Arc length = (θ/360) × 2πr = (240/360) × 2 × (22/7) × 4.2 = (2/3) × 2 × (22/7) × 4.2 ≈ 25.28cm
Perimeter = Arc length + 2r = 25.28 + 2 × 4.2 = 33.68cm

ii. Area of the sector:
Area = (θ/360) × πr² = (240/360) × (22/7) × 4.2² = (2/3) × (22/7) × 17.64 ≈ 29.44cm²

1. b. If the sector is folded to form a cone:
Arc length becomes the circumference of the base of the cone.
C = 25.28cm, so r = C / 2π = 25.28 / (2 × 22/7) ≈ 4.02cm

2. The diagram below shows a vertical tower TF and an observer at point R.

Given: Distance from observer to foot of tower = 7cm

a. Height of the tower (TF):
Let the angle of elevation be 60° (common value).
tan(60°) = h / 7 → √3 = h / 7 → h = 7√3 ≈ 12.12cm

b. Angle of elevation:
If height of the tower is 12cm and base is 7cm:
tan(θ) = 12 / 7 → θ = arctan(12/7) ≈ 59.74°

3. ABCD is a trapezium with AD||BC, ∠BAD = 90°, ∠ADC = 45°, |BC| = 10cm.

Area of ∆BCD = 35cm²
In ∆ADC, ∠ADC = 45°, so triangle is isosceles right triangle.
Let DC = x → height h = x
Area of ∆BCD = ½ × base (DC = x) × height (from ∠BAD = 90°) = 35
½ × x × x = 35 → x² = 70 → x = √70 ≈ 8.37cm
So, height = 8.37cm, top base AD = 0, base BC = 10cm

Total area of trapezium ABCD:
Area = Area of triangle BCD + Area of triangle ABD (right triangle)
But AB = height = 8.37cm
Area = 35 + (½ × 10 × 8.37) = 35 + 41.85 = 76.85cm²

4. Expenditure of a housewife for a particular day:

ItemsAmount (₦)
Rice120
Yams100
Beans60
Vegetables140
Meat180
Sugar40
Palm-oil80

Total Expenditure = ₦720

4.a. Pie Chart:
Each angle = (Amount / Total) × 360°

  • Rice: (120/720) × 360 = 60°
  • Yams: (100/720) × 360 = 50°
  • Beans: (60/720) × 360 = 30°
  • Vegetables: (140/720) × 360 = 70°
  • Meat: (180/720) × 360 = 90°
  • Sugar: (40/720) × 360 = 20°
  • Palm-oil: (80/720) × 360 = 40°

(The pie chart the a circle divided into sectors with the above angles and labels)

4.b. Bar Chart:

Draw vertical bars with the following heights proportional to the amount:

  • Rice: 120
  • Yams: 100
  • Beans: 60
  • Vegetables: 140
  • Meat: 180
  • Sugar: 40
  • Palm-oil: 80

(Label each bar with the item and amount)

How to Pass Mathematics Exam Questions for SS1 Third Term

Passing your Mathematics exam questions for SS1 Third term requires a combination of preparation, understanding, and strategy. Here are actionable tips to help you excel:

Start by knowing all the topics you are expected to cover in the third term. This includes geometry, algebra, trigonometry, statistics, and word problems. Focus on each topic and master its basic concepts.

2. Understand, Don’t Cram

Mathematics is not about cramming formulas or answers. It’s about understanding how and why the formulas work. Always seek to understand the logic behind every method you are taught.

3. Practice Regularly

Solve different types of questions from your textbook, past questions, and assignments. The more you practice, the better you understand how to apply the methods you’ve learned.

4. Memorize Important Formulas

While understanding is key, you also need to memorize some important formulas, especially in geometry and trigonometry. Write them out and revise them regularly.

5. Work on Your Weak Areas

Don’t ignore any topic you find difficult. Spend extra time on it and ask your teacher or a friend for help. Mastering your weak areas boosts your overall confidence.

6. Use Past Questions

Get past SS1 third term exam questions and try to solve them without looking at the answers. This helps you get used to the question patterns and time management during exams.

7. Avoid Distractions While Studying

Find a quiet place to study and stay away from your phone and social media while studying. Focused study time is more productive and helps you retain what you learn.

8. Believe in Yourself

Don’t be afraid of Mathematics. With the right mindset and consistent effort, you will succeed. Always believe that you can do it.

Conclusion: Passing Mathematics in SS1 Third Term is possible if you plan your study, practice well, and remain focused. Start early, stay consistent, and approach each question with confidence.
